Ostkust (Pub. No. 5168)

by A. Mason.

She’s 24 feet from stem to stern, large enough for limited cruises and roomy enough for day sailing.

"Ostkust" was designed to be an ideal day sailer, with a large cockpit that is almost 6 ft. 6 in. long, but yet has a comfortable snug cabin that would be perfect for two people for short cruises or for much longer cruises for two young people who don’t mind roughing it a bit. However, as most of the sailing time is in reality day sailing where ease of handling is desirable, greater emphasis has been placed on designing a roomy cockpit so that a few congenial souls can find ample room for their utmost comfort while enjoying the sunshine and air of a day on the water. In contrast to most so-called day sailers, provision has been made for the installation of one of the many small inboard air or water-cooled engines. The one shown on the plans is a Lauson 21/2 horsepower water-cooled engine with magneto ignition, which is ample to get the Ostkust into port after the wind has fallen to a flat calm at night or when it is necessary to make a train.

Note: Ms. Mason tells us that when her father was on a vacation in Hawaii, he was astonished to see one of his Ostkust's lying at the dock. She had sailed there from Los Angeles!

Tabu- A Planing Sailer (Pub. No. 5169)

Designed by William Jackson

By combining new materials with improved techniques of water dynamics, this sports sailer brings about a new concept of high-in-the-water speed sailing

Speeds of up to four times faster than conventional sailers of comparable size are possible with the "Tabu". To achieve this speed, it rides over the surface instead of forcing its way through it. It performs much like the outriggers made by the Polynesian Islanders whose handmade craft often exceeded 20 mph. Several years of research have gone into designing this sailer. By following the designs given in this article you can build a craft just like the one that we came up with and proved to be a successful planing sailer.

Nugget (Pub. No. 5172)

by Arthur Piver

This 24-ft. trimaran can be built at rock-bottom cost.

The  trimaran  has proven to be not only fast and safe, but inexpensive and easy to build as well. It possesses the ideal sailing characteristics of great stability with light weight. The 24-foot Nugget, shown here, is easy to build, being almost all sheet plywood. It was designed especially for the amateur craftsman and has numerous building short cuts. There are no critical bends, and the construction has been simplified to the point where no lofting is necessary. A table of offsets is not even required. Here we have a boat which can sail at a speed of twenty knots (it is also extremely fast in light airs) and is apparently seaworthy enough to go around the world. The boat is easily trailed, as the side decks and floats fold compactly. It can sleep four people on short cruises, and the 14-foot beam provides loads of useful deck area. Draft (board up) is only 17 inches, so it is easy to beach.

Lazybones (Pub. No. 5174)

by Donald H. Smith, SSCD

This comfortable 24-ft. sloop accommodates two.

Befitting her name, "Lazybones" is a simply rigged, small cruising sloop with an auxiliary engine. She will not be a fast sailer and is capable of only seven knots under power. However, her very significant virtues relate to her simplicity of rig and maximum comfort for her small size. She carries 293.4 square feet of sail with 218.4 in the main. Her gaffheaded rig will require a minimum of effort to handle, even for the novice. From the standpoint of accommodations, "Lazybones" has a small cabin, housing two berths forward, a small toilet enclosure, and a galley. Her cockpit is roomy with two longitudinal seats on either side. Both the tiller and engine controls are within easy reach when sitting on either seat. Under the seats are lockers for the multitude of gear which eventually finds its way aboard small craft of this type. Her forward hatch is a little unusual for this type of small sailboat but is there for good reason. In any cabin boat, especially where there is a galley and stove, more than one means of exit should be provided. "Lazybones" is of stout seagoing construction, which features a round bilge and lead keel. She is not a difficult boat to build, but her construction will be time consuming in that she is carvel planked and the planks must be carefully spiled and shaped. She has steam-bent oak frames and some hefty deadwood in her keel assembly.

Frostfish (Pub. No. 5175)

by Cal Smith

For top speed thrills on ice build this 161/2 footer.

If you’ve never experienced the sensation of flashing over the ice at 40 mph, you’re really missing a thrill. Building "Frostfish" will put you into this exhilarating winter sport and you can do it for $100— less if you already own a sailing paddleboard, dinghy or canoe. "Frostfish" was designed to be quickly and easily built. Ordinary lumber and construction grade steel are used throughout and hardware store fittings are specified rather than more expensive marine hardware. The sail and spars are adapted from the Alcort Sailfish but lateen or Gunter canoe rigs and dinghy spars and sails of 40 to 65 square feet can be used. Completely portable, "Frostfish" can be taken apart or assembled in a few minutes. The body weighs 65 lbs., the runner plank is 40 lbs. and the rig is 15 lbs.—any of which can be handled by one adult. The total 120-lb. weight is easily carried on top of a car or station wagon. This is a fun craft, easy to sail and highly maneuverable. Carrying one adult or two youngsters, she’ll do 35 to 40 mph in 20 to 25 mph winds. And she’s safe. With the low lateen rig, she stays down on the ice where she belongs.

Bantam (Pub. No. 5177)

by Leslie E. Bailey
Secretary, Rhodes Bantam Class Assocation

A 141/2 footer wonderful for racing or day-sailng.

Many experienced skippers have stepped into a Rhodes "Bantam", wondered aloud about the room and comfort in its fourteen feet, exclaimed about its exceptional stability and then found a boat with a real challenge to their sailing ability. For all its good performance, the "Bantam" is an ideal boat for family sailing, one which doesn’t penalize the inexperienced. Another beauty of the "Bantam" is its simplicity. You don’t have to be the best shipwright in the world nor do you need a shop full of special tools. A comfortable chair, a good standard text on boat building and the usual tools of a home shop combined with patience and care and you’re on your way. The "Bantam" is a strict one-design class where home built boats are on a par with factory boats, and there are no “goldplaters.”

Sea Flea (Pub. No. 5187)

by William D. Jackson

Two plywood panels sandwiching a bare minimum of inner framing make up the unusual constructipn of this demon midget sailer. Also out of the ordinary for today’s sailing craft, though the type goes back about 1500 years, is its sailing rig—the lug rig—which is better suited to a small craft such as "Sea Flea" then the more usual Marconi rig. The Marconi rig would require a taller mast with many stays and spreadera; the lug rig utilizes short, easily dismantled spars that can be carried atop an auto as conveniently as the boat itself.

Cat's Paw (Pub. No. 5188)

by David M. Swartout

White, sails, two hulls, and cat-quick speed with this 12-ft. catamaran sailer

Old-time, dyed-in-the-wool sailors sometimes look askance at sailing catamarans because of their unorthodox design. But these same sailors are usually looking ahead at them in a race because of the cats’ speed. For their length, catamarans can carry extra large sails aloft due to the wide, stable platform of the two hulls. More sail area to pick up the wind means more push, and any horsepower jockey knows that more push means more speed. But for the individual who just likes to spread white sails against blue water and isn’t worried about winning races, "Cat’s Paw" has other advantages. She’s easy to build because of the straight-sided hulls. The sheer line is flat and that simplifies building the form. Bow and stern are straight, so there’s no cockeyed bevel to fit and fuss with. "Cat’s Paw" is an ideal boat to learn or practice sailing in, because she will forgive so many mistakes. Operators of boys’ camps should consider building a fleet of these catamarans to add sailing to their water activities program. Boys will get a feeling of speed, learn the rudiments of sailing without worrying about capsizing if a gust of wind hits them at the wrong angle or if they mishandle her in a stiff breeze.

Restless (Pub. No. 5197)

by Gerald Taylor White

LOA 17' 4", BEAM 4', 91/2" DRAUGHT 61/2", SAIL AREA 100 SQ. FT..

Want speed under sail? Here is your answer, for "Restless" was designed with just that requirement in mind. Her shallow V-bottom, short overhangs, and tall inboard rig are all earmarks of a fastsailing racer. The object of the double cockpit is twofold: first to provide strong cross bracing to take the strain when she is sailing with the crew hiked out to windward, and second to keep the helmsman and sheet tender from getting in each other’s way. As all sheets belay on the deck between the cockpits, it is possible to sail the boat singlehanded without getting a tangle of lines in the cockpit. If you are wise, you’ll put that deck in just as it is shown. When you aren’t racing and want to carry some extra passengers, there is still room for them—-in fact, the deck itself makes an excellent seat for those who don’t mind ducking at the order, “Ready about!”

Build the Crosby 16 (Pub. No. 5202)

by Wm. F. Crosby

This little sailboat was designed with several definite ideas in mind. The first was to have a boat that would be so extremely simple to build that almost anyone could do the job with the minimum amount of work and cost. The second idea was to produce a boat that would be virtually impossible to capsize. The third was to combine a hull and rig that would be capable of sailing faster than most boats of its size. That all three objectives have been achieved was shown pretty conclusively by Crosby 16 No. 1, which was built by a New York amateur. First, he did a thoroughly workmanlike job, encountering no difficulties. Second, the resultant boat was stable. Once she was caught in a heavy puff with a jammed mainsheet. One crew member was down to leeward, another was standing on the forward deck, and the skipper was catapulted to leeward as the little boat was knocked down. Despite the force of the wind and the tremendous upsetting leverage exerted by the crew members, she recovered without capsizing. And third, she was fast. In one free-for-all 20-mile race, dead to windward, she finished second in a fleet of over 20 boats. The boat that beat her was much longer and had a great deal more sail area. The boat that came in third was more than a mile astern at the finish. She has a flat bottom, which allows the entire boat, when reaching across the wind in fairly good breezes, to rise and plane, sometimes for as much as a half a mile at a time. Total sail area is 133 square feet, with 88 square feet in the mainsail and 45 in the overlapping jib. The rigging consists of just a jibstay and two shrouds. You need no other wires or spreaders.

Sandpiper--Auxiliary Schooner for Two (Pub. No. 5204)

by William Garden, Naval Architect

LOA 24' 0", BEAM 8' 0", DRAUGHT 3' 0", SAIL AREA 36 SQ. FT.

In a day of flat-sheered, uninteresting sloops, there seems to be a rapidly increasing trend toward small cruising boats with some character. The schooner presented here should catch the fancy of a boy of any age who has a drop of adventure in his blood. Think how she will look anchored off some remote dune or tidal creek with the setting sun picking out the rake of the spars and the lazy drift of smoke from the galley stack. With her black topsides, white wale strake, white trunk, varnished weatherboards, and tanned sails, she will be every inch a little ship and will catch the eye in any company. The first of this model was built by a boy just finishing high school. The photos show her upon completion, the owner having done all of the work by himself in about one year’s spare time. She has sailed and cruised many thousands of miles and has given her owner an endless amount of pleasure. The type is about the simplest sort of boat to build and, with proper handling, can do any sort of sheltered-water cruising.

Jitter-Bug--A 17.5' Cabin Sloop (Pub. No. 5206)

by Hi Sibley

Here is a sloop almost made to order for the amateur builder who wants a boat with a cabin, capable of offshore ocean cruising, with more speed than the average and one that will not run into a great deal for material. It is a sturdy vee-bottom design, and the original boat built by Francis W. Straight of Pasadena, has made numerous trips to Catalina Island., 27 miles offshore from the home port.

Naomi--A 22-Ft. Hooper's Island Skiff (Pub. No. 5208)

by Sam Rabl

Down where Chesapeake Bay begins to get pretty thin as far as its depth is concerned, the boys who catch the delicious soft shell crabs that you get at the high class hash joints—-when you have the money to visit them-—have developed a type of boat that will run in pretty shallow water. The fact that these crabs must be gotten in to the shipping crates in pretty quick time has also made speed imperative in their makeup. The resulting boat is so fast that the boys really go in for racing as a daily diversion and get pretty adept at it. Every once and a while they get so argumentative about the speeds of the various boats that a supervised race has to be staged to settle matters before blows are resorted to. The construction of these boats is so simple that the boys in most cases build their own and many are sold for day sailing to the furriners who visit the Island on vacations. Strange as it may seem the side planks of these boats come from the opposite side of the continent, being of fir, the only lumber at present that is available in lengths long enough to make the sides in one piece. The sailing rig is simpliàity in itself.

Pixie--A Plywood Auxiliary Cruiser (Pub. No. 5211)

by Sam Rabl

From the first line of "Pixie’s" design to the final layouts it was kept in mind that she would be built by amateurs and to this end all difficult work that usually appears on other boats was eliminated. The lines of her construction were faired full size on a mold loft floor to insure that you would get the correct full size dimensions, and a boat was built from these measurements to prove them. Stock size timbers were used throughout and they lean a little to the heavy side so that the boat will be able to take it wherever she goes. She was designed to be built with hand tools and while the power tools will save some labor they are not a necessity. Nowhere in her construction is it necessary to steam a piece of wood, and the bending of a large apron timber as is usual in these types of boats is eliminated by the use of cheek pieces on the sides of the keel. Instead of bending a piece of 2x8 as would usually be the case, it is only necessary to bend the 11/8" by 13/4” oak cheeks and then you can fasten them as you go. Moreover she was designed to take advantage of the increased strength of waterproof plywood, and is built on a system of longitudinal framing developed especially for this planking material. Where the usual boat would employ numerous transverse frames and a sawed deck beam to match at each one of them "Pixie", it will be seen, is framed around six simple frames, each one forming a complete belt around the boat and tied by its own particular deck beam.

Pirate Too--A Flattie Cruiser (Pub. No. 5213)

"Pirate Too" is a versatile little craft capable of going places without a lot of fuss. As a week-end cruiser for two people who are willing to inject a little “roughing it” into their pleasure, she has proved to be a boat which can get into places where no other boat can go; a boat that is beachable in the event of a severe storm, and that, with a log found on the beach, may be rolled away from the angry breakers. In this event, instead of riding to anchor her crew are snug and dry in their little tent cabin and can sleep it off until the storm subsides. The advent of waterproof plywood and air-cooled motors broaden the field of this type of cruiser and are utilized to advantage in this particular boat.

Sea Rover--A 24-Ft. Auxiliary Cruiser (Pub. No. 5216)

by J. J. Fanta

LOA 24 ft., Beam  6 ft., 11 in., Draft, 48 in., Sail Area 302 sq. ft.

The advantage of this size and type of craft is chiefly roominess and rugged seaworthiness. "Sea Rover’s" construction is all for besting heavy weather. Her 300 square foot sail area is substantial for light wind and weatherable in a blow. A 5 or 10 horsepower engine, which is optional, fits compactly under the cockpit floor behind the companionway ladder. The gas and fresh water tanks are strapped alongside the, cockpit. Forward there is stowage for rope, anchors, etc. Behind this on the port side is a clothes locker, a built-in berth and galley stove. Th starboard side has a berth between the toilet forward and the sink and refrigerator opposite the stove. Space above the berths and fixture is well utilized for lockers and shelves for dishes clothes, spare gear, etc. Turning out "Sea Rover" is entirely within the scope of the amateur builder. If you’ve built smaller craft, the experience will prove handy. Two or three to share the work and cost will find this a fascinating pay-as-you-build project.

Plover--A 15-Ft. Auxiliary Knockabout (Pub. No. 5220)

Here are plans and details for building "Plover", a snappy knockabout sailer that meets the demand for a sturdy, well-built craft for comfortable going. Fifteen feet long, "Plover" is a lot of boat for her size, and yet ideal for single-handed sailing. The five-foot beam makes for a commodious cockpit and the safe pleasure of five or six persons. The sloop rig of 121 square feet handles easily and is very efficient. The entire rig is balanced so that stability is at a maximum. Weighing between 450 and 500 pounds, depending on materials, this sailer is conveniently rowed if necessary, and is light enough to be transported by trailer. A model “B” Briggs and Stratton air-cooled motor is installed to ork the boat in a calm, and in and out of tight harbors or creeks. The little motor is self-contained, needs no batteries to operate and being air-cooled does away with water cooling troubles, a boon where heavy grass or muddy water conditions are encountered.

Meow--A Plywood Catskiff (Pub. No. 5224)

by Ernest A. Johnson, N. A.

"Meow" is a plywood cat-rigged skiff that can be rowed, sailed, or powered with an outboard motor of 11/2 h.p. It was designed especially for the amateur builder, and has proved to be a fast and dry sailer. Its cost is reasonable as the bottom, sides and deck can all be cut from 2 standard plywood panels of 12x4-ft. x 1/4-in. There are no butts and the only seams are at the keel and chine.

Carin--A Fast Auxliary Sloop (Pub. No. 5233)

by A. Mason, Naval Architect.

If a survey were ever conducted on the subject, it would probably reveal that the majority of small auxiliary cruising sailboats are used primarily for day-sailing. Despite the fact that these craft take relatively few cruises, a surprisingly large percentage of the boating public seems to feel that even a small boat has to incorporate all the gimcracks and conveniences that we have come to regard as necessities ashore. And for equally unfathomable reasons, some will cheerfully sacrifice stability to be able to stand erect under the cabin beams. Unfortunately, elaborate accommodations and full headroom just can’t be properly designed into a small boat and still result in an able, seaworthy craft. "Carin" is as close to an ideal compromise of these factors as you could hope to find. She’s a smart little sailer that will prove a source of satisfaction to even the most discriminating skipper. The plans were developed from an earlier design which has been built in many parts of the world and whose owners have enthusiastically reported speed, seaworthiness, and general ability to outperform many larger and well-known designs. "Carin" is only slightly larger than her prototype and can be expected to yield an even better turn of speed.

Southwind--A 22-Ft. Dory Sharpie (Pub. No. 5235)

by H. I. Chapelle

Here’s a small, shallow-draft sailing craft which combines sea-worthiness with economy and, with power, will make moderate speeds.

There is sometimes a need for a seaworthy, small sailing boat of very shallow draft. The “Southwind” was designed to fill this need at relatively low cost and with little labor. The old round-sided sailing dories of New England, and the Seabright Skiffs of New Jersey prove that the flat-bottom may be combined with rounded topsides to make a seaworthy small boat. However, these are usually rather narrow on the bottom and thus can carry only a small area of sail, so to make “Southwind” faster in summer weather her bottom was made wider and approaches the sharpie in proportion. She can be built with or without a cuddy, as indicated in the plans.
