The Krogen FAQ (Frequently Asked Questions) Version 1.1.3 - October 29, 1998 Additions, comments, and corrections should be sent to: Bryant Vann, vann@his.com (please be patient, we're "cruisin'") Many Krogen owners have had the experience of folks inquiring about our "salty" boats. Many, like me, never seem to have all the answers on the tip of their tongue. Here's my attempt to describe our boats and some of their characteristics. This FAQ is a collection of information and pointers to other information sources on the boats produced by Kadey-Krogen Yachts and other closely related topics. Please note: I am in no way connected with any company or dealer/broker mentioned herein. It's focused mainly on the 42' trawler, since that's what I own (her name is Salty Lady) and know the most about. Additional contributions are welcomed, and I'll be glad to add details of the others, if you'll send them to me. I am particularly interested in information that would fill in any of the blanks that remain. My special thanks to Ed Buddemeyer, Endurance, for graciously granting permission to reprint his memorandum on Powerboat Characteristics for all to enjoy. Also thanks to Gale Mutum, Just Us Two, and Grant Breining, Carinya, for providing some tough-to-find details. Another special thanks to Grant and his first mate, Astaar, for introducing us to Krogens in the first place. (Krogen, a Swedish word for restaurant, I think!)

Amazingly roomy interior for its length. Many used by live-aboards and full- time cruisers. (Don't let the snub-nosed profile put you off!) 1.2 38' Cutter - A real cruising sailboat 1.3 39' Trawler - a new boat in 1998. Scaled down replacement for the 42' Trawler, for which production ceased in 1997. 1.4 42' Trawler - about 200 made over the past 20 years, no longer in production. Very popular with full-time coastal cruisers and live-aboards. Some used as passagemakers, as well. 1.5 48' Whaleback - recent addition to the line, roughly a dozen made to date, still in production. Called by some a "Manatee on steroids." Incredibly roomy interior. Outstanding live-aboard boat. 1.6 48' Trawler - hull #1 shipped to US in late '95. Hull #2 also delivered (and most likely a half dozen more). Looks almost exactly like a 42' Trawler scaled up. Hull is made from same mold as 48' Whaleback. Same technical and performance specifications as the 48' Whaleback. 1.7 54' Trawler - ketch-rigged trawler. Eight of them built. 2 The 36' Manatee 2.1 Technical Description and Features Full-displacement hull.

Construction: Closed-cell PVC foam cored, full-displacement hull. 2.2 Production History and Variations Over 90 of the boats were made between 1984 and 1991, when production ended. Standard configuration has single stateroom forward. Alternative configuration has two staterooms, with guest stateroom forward and owner's stateroom amidships. 2.3 Operating Characteristics and Discussion Perhaps the most dramatic feature of the Manatee is the large amount of liveable space for a craft of her length. Since she has no side decks, the salon runs the full width of the boat, making it wider than the salon in the 42'. Because her beam is constant to well forward, the master stateroom, which in the most popular option is located in the bow, is also very large. Another excellent feature, especially for live-aboards, is the large, covered, aft cockpit (8' x 12') -- again, larger than the aft cockpit on the 42 -- which has been enclosed with side curtains by many owners, adding an additional room, usable in most weather, warm or cool.

Subsequent deliveries are projected at about one boat per month. Krogen currently (Feb. '98) has 9 or 10 boats pre-ordered. 4.3 Operating Characteristics and Discussion Lacking an existing prototype, some information/data is "Guesstimated". The K39 hull is a computer-scaled-down version of the K42 with some similar layout features, and can reasonably be expected to have similar, but not necessarily identical performance & handling characteristics. The boat has full side decks port and starboard (no wide-body option), and a trunk cabin top forward, giving a slightly lower profile and with less "rake" on the Pilothouse windows than on the K42. Also, the sole of the Salon area is closer to the waterline than in the K42. The Boat Deck and Fly-bridge areas are the same as the K42. Krogen currently intends this boat as a strictly "production" (verses custom) series, and limits builder-installed options to the larger engine, an extra window on the rear Salon bulkhead, the optional swim platform and some fabric color choices, and will offer no alternate layouts or custom configurations at this time. The K39 layout features a large centerline queen Stateroom and Head w/ stall shower forward and down a ladder from the Pilothouse, with a stand-up Engine Room w/workbench aft of the Stateroom, under the Pilothouse. The Galley- Salon area aft and down a half-level from the Pilothouse is a scaled down, but very similar layout to the walk-around version of the K48, with Galley to starboard, Desk to port, and Dinette aft to starboard, full-length settee to port. 5 The 42' Trawler 5.1 Technical Description and Features Full-displacement, full-keel hull.

Closed cell PVC sandwich core used in topsides and superstructure. End-grain balsa-cored pilot house and boat deck. Vinylester resin used in first two laminates below the waterline (not used on the older boats). Exterior finish US Ferro gelcoat. 3M 5200 sealants used at hull-to-deck and boat-deck joints. Marine-grade plywood bulkheads with mahogany stringers and frames. 5.2 Production History and Variations Initially produced in 1979 (or possibly as early as 1977). Although the company says they're no longer producing the 42 as of late 1997, they might just make one or two more on special order, we've heard. On the first few boats the boat deck did not completely cover the after cockpit. Switched from 120 Ford-Lehman to 135SP Ford-Lehman at hull # ____ in 1985. Switched from 135SP Ford-Lehman to various others, including American Diesel 135, Perkins 130, (Sabre 135?) at hull # ____ in 199__, when Lehman stopped producing them. Introduced molded headliners at hull # 66 in 1984. Switched from coated-cable lifelines at bow to teak handrails at hull # 66 in 1984. Switched from teak handrails at bow to stainless steel at hull # _____ in 198__. Switched to solid fiberglass below the waterline from PVC foam core at hull # ___ in 19(93?). Additional construction history information from Kadey-Krogen Yachts: Hulls 1 through 6: Hull: Fiberglass sandwich construction, PVC core - gelcoat finish Main deck: (fore deck, alleyways, aft deck) Wood deck beams, plywood, fiberglass and teak. Boat deck: Fiberglass sandwich with plywood squares 4" x 4" core with teak over, wood overhead beams, painted with teak cap on interior, peg board and later fiberglass sheets on exterior overhead. Pilothouse: Same as boat deck, but no teak Deck house side: Plywood, glass covered Hulls 7 through 65: Hull: Fiberglass sandwich construction, PVC core (gelcoat finish) Main deck: Wood deck beams, plywood, fiberglass and teak. Boat deck: Fiberglass sandwich with plywood squares 4" x 4" core, wood overhead beams, painted with teak cap on interior, peg board and later fiberglass sheets on exterior overhead Pilothouse top: Same as boat deck Deck house side: Single laminate, fiberglass with wood stiffeners glassed to inside Superstructure and deck were all painted with PU paint Hulls 66 to hull #___ in 19__: Hull: Fiberglass sandwich construction, PVC core (more recently solid fiberglass below the waterline and foam core above). Main deck: Fiberglass sandwich with plywood squares as core Ð interior fiberglass overhead liners throughout Boat deck &: Pilothouse: Balsa core, fiberglass sandwich with balsa core House sides: Fiberglass sandwich with PVC core Chien Hwa used plywood squares in boat deck on last few boats built (150's), without KKY knowledge Now foredeck is balsa core. (from hull # 165) Most 42s have two heads, with the forward (owner's) stateroom having a double berth, offset to starboard. A number have a single head with a larger forward stateroom with centerline queen berth. Some have two single bunk beads on the starboard side forward. At least one has the owner's stateroom in the mid- section, with a circular staircase up to the Pilot House. The wide-body variation, initially produced in 1989, has it's salon built all the way to the port gunwale with the starboard side deck as on the others. 5.3 Operating Characteristics and Discussion Cruising speed with the 135SP Lehman is 7.5 to 8.0 knots. Range at these speeds is 2,200 to 2,800 nm. Soft chines and high deadrise give an easy, rolling motion, even with following seas. This is in marked contrast to the many semi-displacement "trawlers" of similar size with broad, flat transoms and flat bottoms near the stern, which reportedly have a harsher, jerky motion. At least two west-coast boats are reported to have been modified to carry flopperstoppers built according to a design by Jim Krogen. Most of the 42s are used as coastal cruisers, including the Bahamas and the Gulf of Mexico, although one 42, CARPE DIEM, has made the trip from Chesapeake Bay through the Bahamas to the Virgin Islands, the Windward Islands, and on to the coast of Venezuela. From there the trip took them to the Panama Canal, up the coast of Mexico, and on to California and Seattle. Several are reported to make the trip from Baja California to Alaska several times a year. Another has reportedly made passages direct from Tortola, BVI, to Norfolk. Yet another 42, SAGE (hull #26), (more recently called YARINEL) went from Lake Superior in late 80's down to Venezuela and returned. Another 42, HELEN M, reported she made an "uneventful" 4-day crosing from Galveston, TX, to Isla Mujeres, Mexico (690 miles). Her favorite places on the cruise included Rio Dolce and Guatemala. The return trip was from Isla Mujeres to Fort Myers, FL (430 miles). The boat is clearly capable of making offshore passages, although prudent skippers will take care, of course, to prepare any boat properly for these voyages -- covering the windows with Lexan plates and considering the addition of anti-roll systems, either active or passive. (Plans are available from the builder for adding paravane-type flopperstoppers.) Visibility from the flying bridge is excellent, especially in tight docking situations. Although the stern cannot be seen directly from this position, the fact that the stern lies directly beneath the edge of the upper deck makes judging close situations easy. Many boats have been equipped with large biminis, and their crews often spend most of their time underway and at anchor on the upper deck. The upper deck carries up to an 11' dinghy easily. Depending on the exact configuration, it may be possible to carry a slightly larger one. The hoisting boom is reportedly stressed to lift up to 500 pounds, although either an upgraded tackle and/or electric or large manual winch would be required. A number of the boats have bow thrusters, and although these provide some finesse in docking, in strong cross-winds and/or current they are no substitute for single-engine boat-handling skills! Coming from sailboats (as many other Krogen owners do), I find the Krogen 42 considerably easier to back down in tight situations than fin-keel sailboats. The raised pilot house is a prominent feature of the boat, providing a completely separate helm station which permits all activities to continue in the salon, galley, etc. without disturbing the safe operation of the boat. A pilot berth (which converts to a double at anchor) just aft of the helmsperson is an excellent place for the off-watch crew in a shorthanded passage to catch forty winks while being immediately available to render assistance if needed. The covered afterdeck is also a key feature, providing, in effect, a lovely sitting porch in warm weather, rain or shine. Many live-aboards have enclosed this deck with doors leading forward to the side decks and plastic side curtains. This provides an extra room in cooler weather and in inclement weather dockside, when the wind won't be coming over the bow as at anchor. It is an excellent live-aboard boat, used for this purpose by roughly 25% of the owners. The foam-filled hull provides good insulation from the cold water in winter. The engine room provides a large space that is more than adequate for maintenance of ship's systems and it has plenty of room for gensets, refrigeration, air conditioning, watermakers, etc. Those of us who came to trawlers from sailboats may have thought of these items as luxuries for years. However, it is remarkable to read the experiences of serious full-time cruisers who eventually want to add all or most of these items eventually. It is certainly pleasant to have the room to comfortably install and maintain these systems.

"Classic" version is similar in appearnce to 42' Trawler. "North Sea" version has reverse-raked pilothouse windshield. It is also available as a "widebody." 7.3 Operating Characteristics and Discussion Looks like scaled-up 42' Trawler with nearly identical layout. Larger pilot house, mid-ship stateroom, after cockpit, and boat deck. Two heads in the version with centerline queen in forward stateroom. 8 The 54' Trawler 8.1 Technical Description and Features LOA..............................54'-5" LWL..............................47'-11" Beam.............................17' Draft............................ 5'-6" Displacement (half load)... ...67,800 lbs Fuel............................1,200 gals Water.............................600 gals Ballast.........................6,000 lbs Engine.......................Super Ford Lehman 225 hp Diesel Hydrostatic data: Displ/length ratio (D/L)........275 A/B ratio.......................2.2 Prismatic coef.

The boats have two aluminum masts and booms with a crow's nest on the forward mast. A 20 KW generator was standard. 8.3 Operating Characteristics and Discussion The cruising range at 7 knots is 3,500 miles -- at 8 knots, it's 2,500 miles. 9 Some General Information on Krogen-like Boats (including single-screw maneuvering) 9.1 Full-displacement Trawlers - A Comparison With Other Boats This is an article written by Ed Buddemeyer and published in the Krogen Cruisers newsletter, Spring 1991 and Summer 1991 issues. MEMORANDUM TO: Yacht Dealers/Brokers FROM: E. Ulric Buddemeyer RE: Powerboat Characteristics Like cars, horses, and women, a yacht may be fast or comfortable, but not both. Unlike the others, a yacht also has to go to sea. The constraints, then, are speed, comfort, and seaworthiness, and the design is a compromise depending upon which attributes are most favored. Before falling hopelessly in love with a fiberglass-lined hole in the water, it is well to have a hard look at the form which necessarily follows the function. When comfort is the leading consideration and seaworthiness can largely be ignored, what follows is a design which does fine tied up securely to a pier. Generally know as "motor yachts," they might as well be described as marine conversions of shore-side motor homes. That's what they're built for and they look it. In profile view, they appear to be a couple of boats high, the better to accommodate fore and aft staterooms with heads and showers, raised saloon, galley, and lounge and flying bridge with extended hardtop covering the lot. Side decks and aft cockpit are sacrificed for the sake of greater room below, so that it is awkward to handle lines when coming alongside. To support all that tophamper, even at rest, they must be broad in the beam and nearly flat bottomed all the way aft to the transom. To persuade such contraptions to move through the water at all requires a great deal of power;to get them to move fast takes even more. Power is available at a price, though, and with enough of it, together with trim tabs to make up for the tendency to squat when pushed hard, even ungainly hulls can be driven 15 or 20 knots over calm waters. On the down side, they behave under way with all the grace and agility that might be expected of a buoyant box wrapped around an apartment. When it blows the least bit, they are dangerous at sea and better off in their slips. I can't put up with that constraint. When speed is the leading consideration, seaworthiness a real concern and the accommodation fitted into the space left over, the result is a sportfisherman or something very like it. At my own yacht club, one such specimen of the breed is named "NO COMPROMISE," a forthright declaration of no-nonsense purpose. To engage effectively in the business of sportfishing, a yacht must necessarily be strong, powerful, fast, and able. While lavish accommodations are always nice to have, the hull and topsides cannot be bent all out of shape for the sake of superfluous creature comforts without spoiling the performance. The yacht is a sportfisherman, appears to be a businesslike vessel and can't be mistaken for a floating condominium. Were I more interested in fishing, or even just getting around in the Bay in a tearing hurry regardless of expense, that's the way I'd go. Where comfort and seaworthiness are major concerns and speed can be neglected, trawler yachts are often thought to fit the bill, but most are disappointing. Real trawlers are pure displacement hulls built to heavy scantlings and designed to keep the sea. Yacht trawlers imitate the real thing in appearance and in that they are ordinarily operated efficiently at displacement speeds, but there the resemblance to their seaworthy sisters ends. Most are built with the so-called "semi-displacement" hulls, a compromise which means that if anyone is fool enough to load them up with excess horsepower, they might struggle up on their broad, flat, heavy behinds onto a laboring semi-plane at a blazing ten or twelve knots. Their behavior in a following sea is, if anything, worse than the faster sort of dockwalloping motor yacht, as the trawler cannot possibly outrun the waves and so gets shoved around by the stern, tripping over the bow and constantly threatening to broach. Such misbehavior is characteristic of slow, flat-transomed, semi-displacement hulls and can get dangerously out of hand in seas of no more than moderate size. I've had quite enough of that. There are a few designs which might be called "no compromise" trawlers. These are full displacement hulls with no pretensions of speed. They can be laden with all sorts of creature comforts with negligible effect on their sedate pace through the water. Since there is no intention of lifting the whole works onto any kind of semi-fast plane, the after sections need be neither broad nor flat. All boats are fine at the bow but displacement hulls may also be narrowed and rounded aft as well so as to yield to overtaking seas without stumbling. At displacement speeds, deep draft is not an impediment, so that the hulls can be fitted with a proper keel having a firm grip upon the water, large attached rudder, protected prop and inherent directional stability. Power requirements are modest, operation is economical and the range is therefore very long. When speed can be sacrificed, the sea-kindly, full displacement hull is the best way to go the distance in reasonable safety and comfort, altogether a sensible arrangement for anyone who expects to spend a considerable amount of time away from the shore. There is yet another alternative worth considering for the man who wants to go to sea in safety, get there and back at a smart pace, and doesn't require all the luxuries of home along the way. That is the yacht version of the "Down East" work boat. Out of that sturdy heritage come hulls built with serious purposes in mind, among which are sea-keeping ability together with a good turn of speed, both obtained in economical operation. They are long, lean, and low with rounded chines, full-length keel, protected prop, and attached rudder. They track hot, straight, and true in following seas. Going to weather, they slice through the waves without much pounding, albeit with a good deal of thrown spray. They are easily driven with a single engine to speeds of twenty knots or so. For use as a yacht, their most significant drawback is that they cannot be heavily burdened with massive creature comforts without spoiling their seakindly behavior. As a result, the accommodations tend to be on the spartan side when compared with other motor yachts of similar length or equivalent cost, certainly not the kind of boat that charms the ladies, say. Even so, if I had the time and money to go through another interlude before settling on the ultimate yacht with live- aboard accommodations, I'd love to try out a handsome, fast and able Down Easter for a spell. Here, then, is the sum and substance of my interest in power boats. Forget the so-called "motor yacht." If I didn't care all that much about how a boat looked or behaved, I'd as soon have a houseboat (which I don't want). A sportfisherman would no doubt be a thrill to bash about in, but I'm not into fishing and don't want to bear the cost associated with that indulgence. A semi-displacement "trawler" is neither fish nor fowl, doesn't ordinarily exceed displacement speeds and even the best of them behave so badly in following seas as to give daunting meaning to the "small craft" warnings that were formerly cause for rejoicing when I was sailing. Find me an able, full- displacement hull with creature comforts (e.g. a Krogen 42) at reasonable cost and my business is yours. A handsome "Down Easter" might be tempting, but the performance* would have to be impressive enough to make up for the limited accommodations, and I'd have to be convinced that the boat could be resold locally without unreasonable loss. ------------ * If it won't go twice as fast as a trawler (a solid 15 knot cruise on a single diesel) then the sacrifice of creature comforts and fuel economy together with the noisier operation and jerkier ride is not worthwhile. Also, if it requires the complications of twin engines to cruise, it is not a Down Easter and has neither market nor operational advantage over a common sportfisherman. 9.2 Single Engine or Twin? - Some Comparisons The following is part of an article I posted to rec.boats.cruising in June of 1996 as part of a thread on Trawler FAQs. A question had been asked regarding the relative advantages of single engines vs. twin -- in a trawler in particular. "> My reading, personal experience, and discussions with other trawler owners have indicated the following regarding twin engines vs. single engines in these boats. Twin engines have twice the purchase cost, twice the maintenance cost, higher fuel cost, and usually, though not always, somewhat higher speed. They also provide greater maneuverability in very tight quarters around docks without using spring lines -- a skill that's not hard to learn but is probably essential in brisk crosswind and/or cross-current situations with single- engine trawlers, even those with bow thrusters. Another vital skill in handling single-engine trawlers in tight spots is "backing and filling," a technique that will allow you to turn the boat 90 or 180 degrees within slightly more than her own length. There are other single-engine techniques as well, but this is a start. It's amazing what you can do with some practice! Still, twin engines should give you better control in these situations. Twin engines may also provide an increase in reliability, though not as much as one might think. This is because the most likely cause of engine stoppage (I am told by engine "experts") is blockage of primary fuel filters which is usually a single-thread failure point -- i.e., both engines usually use a single, common primary filter, so when one engine stops the other does also. The most common method of avoiding blockage (whether the boat has one or two engines) is to add a vacuum gauge after the primary filter to indicate the degree of blockage long before it becomes completely blocked so the primary filter can be changed before the engine(s) stop. Even more elegant is to use a day tank into which the day's anticipated fuel is pumped through a separate filter so you are certain the fuel is clean even BEFORE it gets to the primary filter. Finally, dual, parallel primary filters on a manifold permit rapid switch over to a clean filter without stopping the engine(s), if the filter became blocked before it can be changed. On the other hand, twin engines do provide redundancy for failures of fuel pumps, water pumps, cooling water leakage or blockage, lubrication oil leakage or blockage etc. One of the most serious causes of engine and/or drive train damage and failure is accidental grounding or striking large semi-submerged objects with the screw. Here, the single engine designs usually fare much better than the twins. The reason is that the single screw is usually protected by the keel which is directly in line with the screw and projects below it. In the case of the full-keel, full displacement trawlers (like the Nordhavns and Krogens), the screw is almost totally protected by the keel. On the other hand, most of the twin engine boats, especially the semi-displacement designs, have relatively less protection of this kind. I have seen at least one boat with extended skegs/keels in front of both twin screws to minimize this kind of failure." After reading an earlier version of this FAQ, Andy La Varre suggested I add that the possibility of a broken alternator belt would put a plus sign in the twin-engine column. Certainly here's a case where you could keep her moving with the second engine, if you had it. (The immediate problem isn't the loss of the alternator, of course, but the fact that this same belt often drives the fresh-water coolant pump, as well.) He further suggested that if you have a single engine, be sure to keep the spare fan belt right by the engine (perhaps along with the wrenches for the alternator bolts and the bar for putting tension on the belt), rather than hiding these things in separate spares or tool boxes. Great suggestion! For more thoughts on the relative advantages of single and twin engines, see, "Single or Twin Engines -- Which Is Best?" by Bill Parlatore in the Fall 1996 issue of Passagemaker. Lots of input from a wide variety of engine experts. For additional information on using spring lines for maneuvering in tight spaces -- whether with single engines or twin, see "Boat Handling Under Power - A Motorboat and Yacht Owners' Guide" by John Mellor. 9.3 Backing A Single-Screw Trawler into a "Bare" Slip -- Springing a Pile. (Originally demonstrated to me by the crew of Carinya, Grant and Astaar Breining.) This technique will allow you to back into a narrow slip with no lines previously attached, with cross winds and/or current, and with a fairway barely wider than the length of your boat, using only one fearless line handler aboard your boat and without breaking a sweat. Read on... Keep in mind that this is a LOT easier to do than it is to describe -- especially using ascii "art"!! Have your crew prepare a Spring Line which is as long as the slip plus 10 feet or so. It needs to have a fixed loop or a slip-loop in the end that will be placed over the piling. (It doesn't need to be a "heavy" line, even for a 20- ton Krogen a 1/2" nylon line is fine.) Flake this line down at the stern of the boat so it can run free without tangling. We use a figure eight configuration. For the Slip Configuration and Approach Direction below, place this flaked line on the deck at the starboard stern. If you have hawse pipes by the stern cleats as the Krogen does, run the looped end through the hawse pipe. (Since the Krogen 42 has a hawse pipe/cleat on the side at the quarter, this is the hawse pipe/cleat we use.) Also prepare two bow lines (the longer the better, especially if the slip is longer than the boat) and two stern lines and flake them down by their respective hawses pipe/cleats. Note the piling labeled "A". It's the outer piling in the Target Slip farthest from you as you approach. For this particular slip configuration, this is where the "real" action is going to take place. Slip Configuration: Narrow Fairway Direction of Approach ------> o o o o <- Outer Pilings A o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Step 1. Slowly bring her into the fairway close to the outer slip pilings. -----------\ ~~x Boat > -----------/ o o o o <- Outer Pilings A o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Step 2. Now, as you near your Target Slip, bring her starboard stern as close as possible to Piling "A" and stop the boat. You may need to kick her bow out just a bit to avoid other boats in their slips, but the key is getting your crew close enough to Piling "A" to reach it with the Spring Line loop. There are several methods of using boat hooks to get some extra "reach." Of course, the lasso method (the cowboy technique or underhanded "u-toss") is also a possibility... -----------\ x Boat > -----------/ o o o o <- Outer Pilings A o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Step 3. Have your crew place the loop of the Spring Line over Piling "A" and standby to tie it off at the starboard stern (or quarter) cleat. Back up slowly 6 feet or so, stop, and have your crew tie the Spring Line off. (The optimum distance required will be determined by the width of the slip, but 6 feet is sufficient -- more is better if you have the room.) Now back SLOWLY, and the boat will begin to rotate into alignment with the slip. Don't fret about a few squeaks -- that's what the rub rail is for. The entire process can take 30 seconds or more, depending on the strength and direction of the wind and current -- sometimes they will help, sometimes not. Use your bowthruster to assist the turn if you like, but it's not necessary -- just speeds the process up a little. Carefully watch the port stern side to make sure it clears the other Outer Piling as you make the turn. If it doesn't clear, stop backing, go forward slightly, and have your crew shorten the Spring Line and re-tie it. Then resume backing SLOWLY. -----------\ x Boat >~ _----------/ ~ o o o o <- Outer Pilings A o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Here's what you'll look like part way through the turn. You'll only need to miss the piling with the port quarter by inches. Since you're moving so slowly, there's no need for panic at any point (unless you've left the barbeque attached to - and hanging outboard from - the port cockpit stanchion -- 'nuff said!). _ / \~~ / /~~ / /~~ / / o o x /o o <- Outer Pilings A o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Step 4. When the boat is perfectly aligned with the slip, have your crew release the Spring Line and let it run free. You now begin backing into the slip (using the backing technique described in the following section or whatever you feel comfortable with to control the direction of the boat). : / \ | | | | o o| |o o <- Pilings | |!<- Spring Line x o o o o <- Inner Pilings l-------------------------------- l Dock l-------------------------------- ^ Target Slip Step 5. While you are backing, this would be a good time for your crew to place the loops of the bow lines onto the 2 Outer Pilings -- this is especially important if the slip is longer than your boat -- you may not be able to reach them easily later. Don't tie them off quite yet,though. When you are all the way into the slip, stop, and have your crew tie off the Spring Line to prevent the boat from hitting the dock. It should now be obvious why the Spring Line needed to be so long! (If the wind is blowing (or the current running) from your stern, you may need to keep "bumping" reverse to keep the Spring Line tight so you won't be pushed away from the dock while the stern lines are rigged. Your crew should then rig a stern line to the windward (or up current) Inner Piling and then you or your crew should tie off bow line attached to the windward (or up current) Outer Piling. You are now secure temporarily. Congratulations! You've done it! The remaining dock lines lines can be rigged at your "leisure." o o o o <- Outer Pilings / \ ! | |! | |!<- Spring Line | |! | |! o o x o o <- Inner Pilings l-------------------------------- l Dock with cheering admirers l-------------------------------- ^ Target Slip Step 6. Bow to the awestruck observers and cheering admirers on the dock! Go get a cold one -- you both deserve it -- remember your crew did ALL the hard part! 9.4 Backing Her In -- with Dignity and Grace The following is part of an email message I sent to a fellow powerboater in early '95. We were trading ideas on how to back a single-engine craft into a slip. This technique for coming straight back picks up at the point where you already have her lined up with the slip and her stern just ready to enter. "You'll get the hang of it. Here's MY secret. (discovered quite by accident) Clearly you have to plan ahead or do what's called "springing a pile" to get her more or less positioned correctly and lined up with the slip. That done, I turn the helm ALL THE WAY in the direction she wants to back due to prop torque. I do this rather than try to fight the torque effect for two reasons. (1) There's no way to counteract that effect with the rudder at low speeds no matter what you do because the rudder is almost completely ineffective at low speeds in reverse. (2) BECAUSE it's so ineffective, turning in the direction the boat naturally wants to back doesn't make it turn that way any faster. However, it gives you a terrific ability to "steer" with brief bursts of forward as described below. Now, here's what you do. Give her a gentle amount of reverse to get her started moving backward. Then go back to neutral once she starts moving. (Remember, the prop torque effect only occurs when the prop is turning, so she'll go straight back by herself when she's in neutral.) She'll turn off course a bit, and you correct this with a QUICK burst of forward. Don't be timid about the burst. Because of the prop wash on the rudder, this has the effect of "hopping" the stern back into position without causing any forward motion. (If you have a little extra room, you can overcorrect some here to anticipate the effect of the prop torque during the next operation in reverse.) Now you're ready to apply some more reverse. Repeat the process until she's all the way in. She goes back in a series of small arcs, but the result is a VERY professionally executed maneuver. Throughout this, I depend on the outer pilings to keep the bow from falling off downwind in the event of a fresh crosswind (which inevitably pops up out of nowhere just as the dock becomes lined with well-wishers and hecklers while you try to look "cool")." 9.5 Maneuvering the Single-Screw Trawler: The Art of "Goosing" to Make 360 Turns Back in November, 1997 a lively thread popped up on the Internet Trawler-World mailing list, TWL, on Single vs. Twin engines. This perennial subject quickly evolved into a discussion of how to maneuver a single engine boat -- an art that must be learned by a Krogen captain to be able to look "cool" and avoid serious damage to one's boat and pride (not to mention others' boats). I tried to describe in text form some tips on how to do this, and judging from the responses from others on the list, it seemed helpful. Although this sort of stuff is "old-hat" to the long-time, single-screw skippers, I thought some of the new folks in our club might find it useful It all started with the following two quotes. (In Internet email quotes from some else's messages are usually denoted my the ">" marks at the left margin.) >"October would occasionally simply decide she wouldn't turn to port. We >got tired of doing 270 turns." and >Exactly. My present single engine boat has a keel and a lovely great >rudder but with any wind blowing ( a Mistral can go on for a week) you >can forget about backing her anywhere but left about. The 270 degree >turn is often the only option I've had in a medium wind - and it's >great luck if I've got room for one in a Mediterranean harbour - or on >our narrow canals. At the risk of stating what may be obvious to some of the folks on this list, I'm going to toss my $0.02 into this part of the thread... First of all, I've had this identical discussion with some of the single-screw owners in our marina and the ones who've been bold enough to try these techniques have told me the experience has been very helpful. The first "secret" to tight-quarter maneuvering the single-screw boat is to learn how to "back and fill" to "rotate" the boat, not "drive" her around. Using this technique, you can do 360-degree turns in EITHER direction in less than two lengths of your boat -- and, if you get good at it, it'll be 1.5 lengths or so. This technique consists of stopping completely and putting the helm all the way over and leaving it there throughout the turn. Then shift into forward and give the engine a quick "goose." You really have to hit it hard, so the first time you practice this, try it out in the harbor where you're close enough to objects to see the effect of what you're doing, but not so close you're likely to get into trouble. As soon as you've "goosed her" forward, throttle back, then immediately shift into reverse and "goose her" again -- hard enough to kill all forward motion. You will see that the forward goose has rotated the boat perhaps 30 or 40 degrees and the reverse goose has killed her way again so she's barely moved forward. Repeat the process over and over until you've rotated the boat the desired amount. Of course, because of stern walk in reverse, you'll find this works better in one direction than the other. For example, our boat backs to starboard, so rotating the boat to port is MUCH easier because BOTH parts of the maneuver (forward AND reverse) assist the turn, whereas when you turn her to starboard the reverse goose tends to slow the turn. However, it CAN be done in both directions -- even in a breeze. Start by practicing the "easy" way and THEN work on being able to do it the "hard" way. Leave the helm alone during the maneuver -- it's only effective in forward anyway. The second "secret" to this is that you can NOT be gentle with the power when you "goose." Think of it as handling a mule, not a lover. It will makes LOTS of noise, and if you're in shallow water (say, less than 5 to 8 feet under the keel, you'll kick up a LOT of mud to boot. If you're lucky enough to live in an area where there are watermen (who most all use single-screw boats -- think about it!), watch THEM turning and backing in small spaces. In our area, you can hear their engines a mile away doing this. Observe the action of the stern during the forward goose -- it seems to almost "hop" over several feet in the direction you want it to go. As you watch what's going on during the turn, you'll note that you're effectively moving the stern around the bow -- or at least a point maybe 25% back from the bow. This is quite different from what the twin-screw folks can do by pivoting around the stern -- or at least a point maybe 25% forward of the stern. Nonetheless, it works pretty well. Here's the rub. While you're doing all this, the wind and/or current is causing you to drift. Start by practicing this on a calm day. THEN, when you can do it quickly and smartly, try it in the wind. The quicker you turn, the less distance you'll drift. When trying it in a narrow slipway or around docks, you'll just need to allow for the drift by starting your maneuver a suitable distance up wind or current. You'll also find that this works a lot easier with a semi-displacement boat (with very little keel aft) and with fin-keel sailboats (that's where I learned this), but it will work with the full-keel trawler (or sailboat) -- it just takes more of a "goose" (and MORE gooses (geese?) to make the turn. After you've gotten pretty good at this, take her into a slipway where the boats don't hang out the ends of the slips and practice making the turns in tight quarters. If you have a flybridge, that's the best place to do this from so you can watch both ends of the boat. If you only have a lower station, you'll want to put a spotter on the stern to watch your distance from the pilings. Do this the first time on a calm day. Soon you'll be doing it confidently in a bit of a breeze. OK, so far, we have only talked about rotating the boat, but there's yet another maneuvering requirement that's just as tough for the single- screw boat -- that's backing in a straight line. It's really not all that hard IF you remember secret #2. Always use quick, hard bursts of power when you "goose." This will let you complete the maneuver in shortest order, minimizing the drift due to wind and/or current. OK, let's say we want to back our boat (that backs to starboard due to propwalk) slowly into a narrow slipway. Start by lining up with your stern headed in toward the slipway and put your helm all the way over to starboard (and leave it there). (WHY put the helm to starboard? Because when you're backing slowly the helm has very little effect anyway -- especially with a full-keel boat, so putting it to port won't do much to counteract the natural tendency of the stern to move to starboard anyway, and we're going to need the helm to starboard for the "gooses" -- you knew that had to be coming, right?) Now, put her in reverse and give her enough throttle to get her moving in reverse. As soon as she's moving backward (and starting to turn to starboard), shift into neutral and coast. This will stop the propwalk and let you coast almost straight back. As you start to slow, shift back into forward and give her a quick goose. Because of the starboard helm, this will "hop" the stern to port without moving forward (completely offsetting the propwalk -- plus maybe a little more), and then you can then repeat the process. Now, this may sound a little complicated (you'll be following a slightly "scalloped" path), but you can back as slowly as the wind/current conditions will allow without terrorizing yourself or the other owners in the yard. Now, wouldn't it be easier to get a bowthruster and let the bowthruster do all the work? Sadly, no, at least not with a 20-ton, full-keel boat and most electric bow thrusters (although hydraulic thrusters of, say 25 hp or so, can be very effective). Even in calm conditions, you can only move the BOW with the bow thruster, so offsetting the propwalk is easier with the gooses, since THEY move the stern back into place. We have a bow thruster, but I seldom use it -- relying instead on the techniques I've been talking about here -- they're MUCH more reliable. The bow thruster is a 5-hp, 12-volt model that draws nearly 400 amps from a dedicated 8D battery located about 2 feet away. As I recall, it puts out around 150 lbs of thrust, maybe a tad more. However, it doesn't take much in the way of marine growth to reduce that thrust significantly. On the other hand, the 100+ hp main engine can always be counted on to be sufficient. On the other hand, I only count the bowthruster for a little "finesse" in calm conditions -- in conjunction with these other techniques. By itself it won't prevent a disaster in a fresh breeze. Finally, practice these maneuvers over and over until you feel comfortable with them. Pick a calm day (during the week when nobody's around) and practice backing into every slipway in the marina. Then, when you think you're ready, come in bow first and practice backing out and then doing 180s to get out. THEN, pick out a few empty slips well into the slipway and practice the 90-degree turn to line up with the slip and back in! (Believe it or not -- I find it easier to back into a slip now than trying to come in pointy end first.) If you have sturdy rub rails (let's hope you do), get used to letting them touch the pilings, gently of course -- otherwise you'll need a helper to fend off occasionally. The key is practice and MORE practice (along with quick, hard geese) so you know exactly how YOUR boat handles. For some discussion on backing a single-screw boat into a slip with spring lines (which is even slicker), check out my Website: http://www.his.com/~vann/KrgStuff/Krognidx.htm PS. PLEASE don't let your boat know I likened her to a mule! Later another TWL subscriber made the following comment, in part: >I have a marvelous collection of very fuzzy texts in English, French >and German too, where the GOOSING principle is decidedly not stressed. To which I replied: This comment (and several other similar ones) prompted me to check in the various texts on boat handling I have lying about. Know what? You're right! Only ONE even came close to describing the "backing-and-filling" technique. The one that does describe it is "Boat Handling Under Power," John Mellor, Sheridan House, Inc., 1993. Unfortunately, John doesn't use this term to describe it however. On p. 37, he describes "Turning at Low Speed," where he states, "It is essential to appreciate that a boat with a rudder can best be turned at low speeds by driving a powerful flow of water from the propeller across the rudder; the slow water flow past the boat will produce very sluggish steering. A tight turn can thus be made by using a succession of short, sharp bursts of power, maximizing the turning effect of the slipstream while minimizing forward movement." (For some reason he doesn't mention using reverse to aid in minimizing forward movement.) However, in the succeeding section, "Turning Short," John goes on to state, "A single-screw boat with a rudder can, surprisingly perhaps, be turned more tightly than twin screws, being capable of a three-point turn quite literally on the spot... The secret is to make the initial turn against the propeller effects, giving a brief hard kick ahead to swing her with the slipstream over a fully angled rudder. As soon as the stern begins to swing, put her full astern and allow the increased prop effects in astern gear to continue pulling her stern around; there is no need to alter the position of the rudder as it will only have effect when the prop is going ahead. Then go ahead again as before, and repeat the whole cycle as often as necessary. As long as you never allow the boat to actually gather way ahead or astern, simply using prop effects or slipstream to swing the stern sideways each time, she will turn on the spot quickly and powerfully. The more nearly stopped the boat is to begin with, the tighter the turn." Now if he'd only called it "goosing!" (;^) BTW, I recommend John's book (I have the paperback edition) VERY highly. He describes a LOT of techniques that will be useful for handling trawlers -- like how to move the boat directly sideways (without turning at all) using the bowthruster, docking alongside, maneuvering in wind and current, how to use spring lines and warps (very important, IMHO, when clearance for a turn is only inches, rather than feet -- and a LOT easier to do than it sounds, even short-handed -- especially if you have a sturdy rub rail), narrow-waters handling (including how to "read" your boat's message to you that she's getting too close to shallow water for comfort), an so on. He also describes the Mediterranean moor (including how to do it in a strong crosswind). Only "biggies" missing seem to be the Bahamian moor (more of an anchoring technique than a maneuvering technique, I suppose) and how to cross a bar with a strong following sea that's moving faster than you are (often the case with trawlers). Since the helm responds BACKWARDS under these conditions, I think it deserved some discussion. Another topic which could have used some discussion is what I call "weather cocking," the tendency of a boat that's dead stopped to turn it's bow away (usually) from the wind. It's VERY useful to understand exactly how your boat behaves when dead stopped in a wind, because this turning effect can be too powerful to counteract without heroic measures. Better to understand what she's going to do and then plan wherever possible to take advantage of it. This is particularly necessary with backing-and-filling in tight quarters where you don't need to be battling any adverse forces. (Of course, you'll always have to consider the downwind drift due to the wind -- both in planning where to start your turns and in completing the process smartly to reduce the time you're exposed to the wind effect.) Next time you're out in a good breeze, stop dead in the water with your bow either just off the wind or a right angles to it. Now, watch what happens. Of course, the boat will start to drift downwind. That's expected. However, note that it may TURN also. How she turns and how fast she turns may be VERY useful to account for in tight quarters. For example, a sailboat under power (sails furled) will almost always "weathercock" with her stern toward the wind. With a fin-keel sailboat, this will happen VERY quickly, regardless of her angle to the wind when you stopped. (The reason is that the wind pressure on the mast and above-water portion of the hull acts forward of the spot where the water acts on the underwater portion of the hull, including the keel.) With a trawler, this effect may not be as dramatic and could, I suppose, be exactly the opposite, depending on the design of the hull and deckhouse location. Our Krogen 42, for example, hardly turns at all. (Frankly, I preferred the rapid turning of our old fin-keel sailboat!) Why? Well, when I planned my tight-quarters turn with the sailboat, I would intentionally stop with the bow at least 20 degrees or so off the wind IN THE DIRECTION I WANTED TO TURN ANYWAY. Thus, this turning effect aided the backing and filling rather than opposed it. Now, I have to do ALL the turning work myself. I strongly suggest you find out how your own boat behaves in the wind when stopped -- do it out in the harbor where you won't have to worry about hitting anything as you drift along, and then use her tendencies to your advantage when you can. PS. John also mentions in his book the importance of pausing in neutral long enough for the gears to stop turning when shifting from forward to reverse and back. It should go without saying that the engine should be at idle speed before shifting into either forward or reverse. At the very least, high-speed shifts can cause the damper plate to disassemble itself or, even worse, cause the transmission itself to do so. (:^( To which another TWL subscriber, added: >The video "Single Engine Boat Handling" by Bennett Marine does show and >explain the back and fill turn somewhat.

In early 1998 I received an email message from Anne Morris, M/V Tenacity, GB 32 on the York River, VA, as follows (in part): >May I ask you to post one thing to the list? You mentioned (a while >back) a special trick your wife has for handling spring lines on the >approach to a dock, and said you thought you'd already covered this >elsewhere.

Lessee -- I checked my messages and couldn't find it either (I'm sure I wrote about it somewhere -- maybe on rec.boats.*) Anyway, I'll try to keep it short (ha!). If this is old hat, just hit the delete button... BTW, this sounds like basically the same technique that Jerry & Pam Munson, M/V PassageMaker, use. The "secret" is that the after spring (leading from the mid-ship cleat to a piling near the stern) is the first line on -- always. Of course, it really doesn't make much difference if there's no wind or the wind is coming from any direction except OFF THE DOCK, when it's CRITICAL. Once that spring line is on, going forward slowly (with the helm hard away from the dock) will virutally pin the boat to the dock -- totally immobilizing the boat as long as you're idling forward and giving you all the time in the world to put other lines on. Since we back to starboard, I try to dock starboard side to if at all possible. That's because my wife stands on the quarter to put the spring line on a piling -- and I need to be able to get her close enough to reach the piling. Since we BACK to starboard, I use reverse to bump the stern over to the dock (the helm stays hard to port throughout, so going forward with a quick "goose" also moves the stern toward the dock. All the while I pretty much ignore the fact that the bow is falling off, because once the spring line is secured, it's easy to bring it back. (Of course, if you have 3 or 4 hands on your arms you can use your bow thruster some, but most of the time it's neither required or effective. But I'm getting ahead of myself... Here's the setup. Assume the dock is ahead of you and to starboard and a brisk wind and/or light current are coming directly off the dock. Also, assume that it's just you and your first mate (FM) on the boat, and there is no one on the dock to help. The problem of course, is that if you just make an approach at the usual angle of 20 or 30 or 40 degrees and then smartly cut the helm to port and use reverse to stop perfectly -- parallel to the dock and just 3 fingers away -- your first mate has about a millisecond (if you're lucky) to tie on just one line before you're drifting merrily away into the creek. If your FM misses, you have to be ready to pull her/him closer for another try. Since we have LOTS of power at the stern (and only 5 hp on the bowthruster) and it can be vectored with the rudder, I place my FM on the starboard quarter, at or near the stern, and consider it MY job to get her close and keep her there until the spring line is secured. When I go into reverse (and "goose"), the stern moves closer, and when I go into forward (and "goose"), the stern also moves toward the dock. If I "goose" quickly, I can get the sideways motion of the stern before moving the boat forward or back much at all. Successive forward and reverse "gooses" can keep the stern moving toward the dock without getting into the 7-figure mega- yachts ALWAYS parked only a few feet ahead and astern. With some practice to build your skills and confidence, you can park UNDER their bowsprits this way. Ah, but I've gotten ahead of myself yet again... Back to the approach. This spring line is prepared well in advance. (Also, the bow and stern lines are ready to go ashore as well.) We use a line longer than the length of the boat (I'll talk about why later) with an eye spliced into one end. It's lighter (like 1/2") than our usual dock lines to make it easier to handle during the docking process -- it's usually replaced later with one that's appropriate for the conditions and length of stay. The end without the splice is secured to the mid-ship cleat and then it is led aft to the stern outside all obstructions -- fascia plates, shrouds, whatever. Then the standing part is "tucked" through the eye to make a noose. This is going to go over the piling -- MUCH faster than tying the clove hitch and/or half hitches IMHO -- it's also easier to execute if someone shows up pn the dock at the last minute to "help." Just tell them exactly which piling to loop it over rather than trying to explain how to tie something from Ashley's Book of Knots while your boat "sails" out into the harbor. OK, so now the noose is over the piling, but there's still some slack in the line. Your FM then moves to the cleat (I'll describe an alternative later), takes in all the slack, and secures the line to the cleat. At this point, you go ahead very slowly with the helm hard to port and the boat will parallel park itself against the dock. It's important not to go ahead hard because most mid-ship cleats are going to be too far forward and the bow will tend to come in faster than the stern. That's why you hold the helm hard to port -- to help kick the stern in. If the bow comes in too fast, a quick "goose" in reverse will pull the stern in faster -- you want to keep her parallel to the dock, more or less, as you come in. Then resume going forward on the tightened spring line. (If you're too far forward, a tad of reverse will let the line go slack so the FM can take some of it in.) OK, so now you're pinned against the dock. Your FM can now step lightly ashore, carrying the stern line. Once it's secure, you can toss the bow line ashore for her to secure -- then the forward spring line, etc. Hmmm.... I got ahead of myself once again. Let's go back to the point where you've gotten the stern a few feet away from the piling you want your FM to put the noose on -- but it's still too far away (or too high) to reach without leaning (a BIG no-no). Here's where our "Magic Stick" comes in. This is going to be tough, but I'm going to attempt to describe it in text. The function of this stick is to let her hold the noose out or up 6 to 8 feet and drop it over the piling. There are several designs in the stores, so check the catalogs. Ours is made from a long boat hook. Imagine there are two large clothes pins attached to the boat hook. One is at the far end and the other is about two feet from that end. The "noose" is clipped in to the clothes pins and the standing part is led back to the end of the boat hook you are holding. The noose is open and "loose" -- probably draping down about 3 feet or so -- big enough so you have a BIG hole (2 feet wide and maybe 2 to 3 feet long) to loop over that piling on the dock. Now we don't actually use clothes pins, since they wouldn't be large enough to hold the line, but you can devise something that has the same function that's bigger (I don't think I could manage an explanation of what we use). The key, of course, is that the two clips should hold the line tight enough so the noose won't drop off, but not so tight that the noose won't pull away when it's dropped over the piling and the stick is pulled away and back onto the boat. If all this sounds too involved (like a lot things, it's a lot easier to do than describe), you can practice Jerry Munson's technique, which is to put Pam on the swim platform and move the stern close enough to the dock that she can get off onto the dock and attach the spring line from there. Choose your poison... OK, one last thing. The Krogen 42 has a side deck on the starboard side (on BOTH sides if she's not a widebody model). The midship cleat is built in to a hawse pipe. we usually run the spring line through the hawse pipe and BACK to the starboard quarter cleat (just forward of the stern -- that's what the extra length is for). The FM can then take the slack out of the spring line after the noose is on the piling without having to move forward to the mid-ship cleat. If I'm running the boat from the flybridge, I can see her working the lines, and we can talk without "yelling." Of course, we NEVER yell (;^). Riiiight! At least we TRY never to do that -- "secret-agent" radios help a lot with this -- with those we can yell QUIETLY! I hope all this makes some sense... I hope it's what Anne asked for... I also hope you're still awake. (3<) PS. If the wind is REALLY strong and/or the current is strong (and BOTH off the dock), the approach is going to have to be modified some (the approach is going to have to be more aggressive) -- by either backing straight toward the dock near that elusive piling OR, probably better, by taking the spring line FORWARD to the bow and bringing the bow straight in to the piling. Once the Magic Stick puts the noose on, the throttle is eased and the bow is allowed to fall away while the slack in the spring line is taken in. Once the bow falls off and the boat is roughly parallel to the dock as before, going forward slowly will haul her in tight. Clearly under extreme conditions, there is going to be a LOT of tension on this line. It is critical that there be clear communication between the helmsperson and the FM. You will have to work closely together to make sure the line is secure and hands are clear before power is applied. 9.7 Choosing a Slip: On Port or Starboard? And Going In Pointy End First... Late in 1997 I received an email from Ted Grave as follows: >Just picked up ( last week ) a 32' Grand Banks. Previous biggest boat >was 24' I/O. Only had time for two marina approaches. No dents, >deaths, or injuries, but certainly not elegant! > >I believe I have a choice in slips next year, and would welcome your >input. I have a LEFT rotating prop, so she will pull to starboard in >reverse. It seems to me that, for a beginner, I will be better off >having my slip to my right as I pull into the marina. That way I can >pull up slightly past my slip, and the starboard prop walk will help >spin me around as I back into the slip. > >Your thoughts and recommendation would be greatly appreciated. >P.S. I don't have a bow thruster. I agree. We also back to starboard so I prefer a slip to starboard if we're backing in -- for two reasons -- the starboard propwalk turns you in naturally as you back, AND the starboard propwalk makes it easy to "snuggle" up to the far piling to slip a springline on to make the turn even easier -- especially if the slipway is narrow and theres a stiff breeze or current (see my Website for more on this). If you want to try it without a springline, come in close to the slips on the starboard and then make a turn to port (it will take some practice to figure out when to start making this turn). Do the "backing and filling" as necessary to complete most of the 90-degree turn, leaving enough undone so that the final backing toward the slip will straighten you out the rest of the way. The trick is to get the BOW lined up with the slip (you can always move the stern around with prop thrust). If all fails and the bow ends up too far off to the side, practice "backing and filling" to complete a 180 and go out and try again. BTW, the "free turn" will take a lot of practice, whereas the springline technique will work perfectly the first time and every time. The first time we did it (and it was with the K42), our slipmates all came rushing out to fend off and pass lines and so on. We did it with such grace that they all felt rather foolish, I'm afraid. Later, one commented that it looked like we'd been doing that all our lives. I tried to be gentle when I said it was our first attempt. From then on they never even looked up. BTW, I say all this not to claim we're all that good, it's just that spring lines make just about EVERY docking situation look easy. Whenever we approach a dock (especially with a brisk wind or current coming from the dock) the after spring line is the FIRST line to go on (my first mate uses a clip arrangement on a long boathook to put it on without having to get onto the dock). After it's on, I idle forward with the helm turned hard away from the dock (to hold the stern in tight), and when we're snuggled up against the dock, I get off and handle the dock end of the other lines while my wife handles the boat end (or vice versa). Oh yes, always try to approach a dock starboard side to -- that's because reversing will pull the stern closer to the dock. On the other hand, if you're planning to come in to your slip "pointy end first," I'd rather have the slip on the port side, again, especially if the slipway is narrow. That's the configuration I currently have. The slipway is so narrow that on approaching the slip I can only turn about 45 degrees to port before I run out of room and have to stop. When I put her in reverse (with a goose) to stop, the propwalk continues the turn to about 70 degrees or so. When I go back into forward (with a goose), I get the rest of the way around to 90 degrees and then straighten the helm to go straight in (which is the REALLY tense part, since we only have about 8" on either side in the slip and the boat is too wide to see the separation -- my first mate stands on the side and "calls" the distance in inches to help my know where I am). Now the REAL trick is to stop in the slip without bumping on the starboard quarter because of the propwalk -- here I try to reverse gently and if I get too close anyway (the wind always seems to push us that way to boot), I turn hard to starboard and give her a tiny goose to get the stern away from the pilings on the starboard side. The trick again is to move the stern without moving forward -- tough with only inches to spare. This is where your rub rail is MOST useful! (;^) 9.8 Lassoing a Piling -- A LONG Way Away! I went down to the boat a couple of days ago to set up some lines to make installing the ice eaters a little easier later in the winter. Naturally, one of the pilings is too d*#n far to reach without untying the whole boat and moving her back (WAAAY too much work except as a last resort). OK, so let's try to lasso the piling -- out maybe 15 feet away and 10 feet tall. Of course, the cowboy-style approach is a possibility, but not only is that something I've never taken the time to practice, but I'd end up with a slipknot wrapped tight around the piling, when what I REALLY wanted was a doubled line that would allow me to adjust the depth of the ice eater from the boat. Remembering a article from a few years back from Coastal Cruising (boy, I really miss that magazine -- sure hope those folks can get that going again...), I gave the two-handed, underhanded-toss a shot, and it worked the first time. Whew! I thought there might be a few folks here who might find it useful, so I'll take a shot at explaining it. The reference is "Solutions," Don and Gael Steffens, Coastal Cruising, April/May 1994, p. 52. They learned the trick from Frank and Marjory Moyer aboard Halcyon, their 25-foot Fisher motor ketch. The coolest thing about this is that your 1st mate (or even guests) can learn to do it easily. Heck, "he'll" probably end up being better than you are... Here's the deal, slightly modified from the description in the mag. OK, you need a line that's a good weight for throwing. I use 1/2" twisted nylon. My 3/4" docklines are too heavy, and lighter ones are hard to toss in the wind (but you find the size that's "right" for you). The line needs to be a LOT longer than the distance to the piling and back. The one I used in the example above was 40 feet long, and it wasn't ANY too long. Hold one end in your hand and use the other hand to coil the line, putting a 1/2 twist in every coil so it's nice and round and open and even. When it's all coiled up, split the coil equally between your two hands, AND (here's the hard part to describe) grasp the end of the line between your thumb and forefinger and hold the 1/2 coil in your other fingers (same hand). If you're still with me, do the same thing with your other hand for the other end and 1/2 coil. Now with your other hand... (no, I'm just kidding...) OK, the rest is easy. Stand, facing the piling and stare at the top. From the article, "Both hands now hold coiled line with the two ends held tightly. Staring intently at the piling, throw up your hands as you would toss a basketball underhand and flip the line (both hands at once) over and beyond the piling." Continuing, "The trick in tossing the line is to aim farther than the piling itself. This ensures sufficient line to reach the target." I would add that it helps to toss the coils several feet to the sides of the piling (one on the left, one on the right, obviously), as well as, high OVER the piling top. This makes your aim far less critical. I've passed this tip along to a number of folks. I've NEVER seen anyone miss on the first try. If your tossing line isn't strong enough to use directly as a dock line, tie your dock line onto one end and pull it around. This will free your tossing line for another piling, if needed. 10 Ritual Cocktail Equal parts cranberry juice, orange juice, and Myers Rum (with a dash of ground cinnamon on top?) -- to be imbibed precisely at sundown (+ or - an hour or two). 11 The Owners Clubs 11.1 Krogen Cruisers An informal group formed in 1990, this is largely an East Coast club, although it has members from Michigan to Texas, Canada to Florida (25% of the members), and the Chesapeake Bay (33% of the members) to California and Oregon, plus Canada, Singapore, Hong Kong, and Dubai. As of November 1997, it had well over 100 member boats and over 185 memberships altogether. It publishes a 25 to 50 page newsletter quarterly (back issues are available and all contain highly useful information on operating, maintaining, upgrading, and generally enjoying Krogens) and sponsors several get- togethers, both afloat and ashore, throughout the year. Its motto is "A group of serious cruisers who don't take themselves too seriously." No president or commodore and NO by-laws! Although for many years it was open only to current and previous owners of Krogen boats, increasing interest by Krogen "wannabes" has persuaded the owners to open membership to them, as well.

Flash Alert: As a result of a number of factors (The new edition of Voyaging Under Power, the inception of Passagemaker Magazine, the inception of the Trawler-World website and mailing list on Internet, the growing number of "wannabe" members in the Krogen owners clubs, the outstanding TrawlerFests being held each year in Poulsboro, WA, Solomons, MD, and Stuart, FL,and the cessation of production of new Krogen 42 trawlers), "previously loved" Krogen 42s have become VERY difficult to find (AND their prices have risen more than 40% in the last 4 years! -- and leaving price guides like BUC way out of date, since many sales are private).

NOTES and DEFINITIONS: D/L ratio is the displacement in long tons (2,240 pounds) divided by the *cube* of (the length at the waterline in feet divided by 100) - should be greater than 270 for sea-going trawlers. A/B ratio is the ratio of the area of the vessel above the waterline to that below the waterline - 2.1 to 2.6 desirable, the lower the better. PC is the Prismatic Coefficient - the ratio of the volume of the hull underwater to what it *would* be if the largest section were carried the full length of the waterline - value must be matched to the D/L ratio. L. C. B. is the Longitudinal Center of Buoyancy L. C. F. is the Longitudinal Center of Floatation. This is the point around which the boat effectively pivots when weight is shifted fore and aft. GM is the distance from the center of gravity (G) to the metacentric height (M). (Note, it MUST be positive!)
