Veep--A Hickman Type Sea Sled (Pub. No. 5296)

by William D. Jackson

This roomy 15-ft. Hickman-type sea sled is one that you can build at home.

An inverted-V in the forward cross section of the sea sled stands for victory over the hydrostatic forces that tend to keep ordinary.hulls slogging through the water. With each turn of the prop, the craft leaps forward, taking a huge gulp of air in its maw to lift the hull and keep it riding on the broad planing surface aft. This efficiency, plus the absence of centerline turbulence commonly found in catamarans, allowed 35-mph performance with a single Mercury 45-hp outboard engine clamped on "Veep’s" transom. Construction is as simple as possible for a boat offering performance and roominess. A minimum number of sawn frames are enclosed in a tough stressed-skin of 3/8-in. plywood.

Ace--A Speedy 2-Cockpit Outboard Runabout (Pub. No. 5297)

By William D. Jackson, Naval Architect

Brand new hi-lift bottom design and high-strength longitudinal beam construction make "Ace" years ahead in outboard runabout speed and performance.

Propelled with a 16 hp stock Evinrude, "Ace" has easily outrun conventional boats powered with 25 hp outboards. We found the one we built could do 50 mph—when teamed up with a 40 hp Mercury that had a quickie lower unit. The wetted or planing area of the hull with one person aboard is only about one square foot! With five persons aboard and powered with a 25 hp outboard, "Ace" planes on the after quarter portion of hull bottom. Chines are beveled for safe turns at high speeds. "Ace" is an ideal boat for backyard builders because no building form is required to make it. This feature also makes it an excellent boat for pre-cut boat kit sales if you are interested in going into the boat building business on a part or full time scale. Its sub-assembly construction also lends itself to mass production of completed boats by the assembly line method.

Blitzen--A Utility or Racing Boat (Pub. No. 5298)

by William D. Jackson, Naval Architect

The first "Blitzen" design we built was bought by a boat manufacturer who wanted to win some Class B runabout races. And, by golly, he did just that, with a speedometer clocked top speed of 47 mph, using a Mercury with a special lower unit. Actually, this "Blitzen" design makes either an ideal fast utility boat or a racer hydroplane for Class B competition. Its hull does all right for itself with the more powerful 25 hp Johnson and Evinrude motors in smooth and rough water, and on either the utility or racer hull, its beveled chines give you an easy maneuverability. It also lends itself to quantity production in case you want to make and sell some extra ones for profit.

Hydro-Kart--A 3 Pt Hydro-Dual Kart Engines, The (Pub. No. 5299)

by William Jackson and Wayne Ison

In one week’s spore time, you can build this 50-mph competition-type hull. Powered by those air-cooled high-speed engines, it offers a new thrill afloat.
Have you been wondering what it would be like to run your kart engines on a small three-pointer at top speed with so little of the boat in the water the sensation is that of flying? Here’s your opportunity to get in on karting fun afloat. If your goal is competition, you’ll want to keep the weight of your "Hydro-Kart" below 100 lbs. The best way to do this is to use l/8 mahogany plywood over spruce framing with bronze or monel fastenings. For economy, however, you can use fir exterior plywood and galvanized fastenings which may put you just over the 100lb. mark, but will not noticeably affect nerformance.

Sea Fury-A 15 Ft 3-Pt Hydro Runabout (Pub. No. 5301)

by William D. Jackson, Naval Architect

Now, for the first time, you can build a sleek sports runabout, using a threepoint racing-type hull similar to those that have captured championship trophies in hydro-class competition year after year. With ordinary 35-40 hp motors, "Sea Fury" will begin to plane in her own length and becomes practically air-borne at speeds of 45-50 mph. This, along with the full-length hard chines to dig in on turns, make "Sea Fury" an exciting boat to handle and a money saving project for the back-yard boat builder

Ella-Mae--A 17-Ft. Outboard Cruiser (Pub. No. 5304)

Economical and easy to build, this tough little craft answers the need for a comfortable cabin boat on a budget.
Anybody who can use the simplest of carpenter's tools can build the Ella-Mae, and make an excellent job of her. The trim lines of the hull with its simple V-bottom give the boat a surprising turn of speed, even with a small motor. The original boat shown in the photographs had a 3 H.P. outboard. Despite her enviable performance and obvious ruggedness, the Ella-Mae is probably easier to build than any other boat of her type. She's ideal for the campiing trip or for ordinary pleasure cruising close to home, and can be built in a fairly short time by the man who gets more fun out of cruising than out of construction. Ella-Mae can float in heavy dew; note the circle on the photograph below; that's grass growing just astern folks!

Sportster--A Speedy 12.5-Ft. Outboard Runabout (Pub. No. 5306)

Here is an outboard runabout especially adapted to plywood fabrication. Construction is simplified and easy, while building costs are low. The completed boat is fast, light in weight, safe and sturdy, giving its best performance with outboard motors from ten to thirty horsepower. Sportster may be built with a single open cockpit or with two cockpits as indicated. If high speed is not an objective, air cooled inboard motors may be used.

How to Build Peetee--A 22' 6" Cruiser (Pub. No. 5312)

by Oscar T. Thomas and S. S. Rabl

Her lines and appearance inspired by the Navy's fast motor-torpedo boats (known as PT's), the close-coupled Peetee is a smart, economical craft designed to provide good all-around cruising for the small family, or for two or three friends who want to chip in and build an inexpensive week-ending and fishing boat. She will run you out to the fishing grounds in jig time, and her raised deck gives ample protection from rough seas and spray. This raised deck has the added advantage of providing extra roominess and comfort in the cabin, and it carries out the graceful, sweeping sheer that makes Peetee look as though she were leaping ahead even when standing still.

How to Build Kingfisher--An 111/2 Ft. Utility (Pub. No. 5315)

by William Jackson

Kingfisher is a universal type of outboard rowboat that rows easily but gives its best performance with outboard motors of from 1 to 20 H.P. Despite its rowboat appearance, Kingfisher rivals speedboats of comparable power. It also performs proportionately well with smaller outboard motors. The hull is soft riding, maneuverable, and stable at high speeds, and due to its size and light weight may be transported atop an auto. Built of waterproof plywood, it is simple, cheap, and sturdy, and may be constructed in the minimum of time.

Bluefish--A 21-Ft. Motor Cruiser (Pub. No. 5318)

by S.S. Rable

There's plenty of room aboard this trim little cruiser, and she's fast and stable, too. If you've always hankered for a good rugged cruising boat at a reasonable figure, she's just what the doctor ordered.

In these days of priorities, conservation, work, and worry for national defense the small boat fan has assumed a new importance. The spirit of the small boat men that saved the day at Dunkirk is alive in the breast of the American boatman and when he builds a new boat he realizes the great service his boat can render. Before the days of all the modern contraptions, ships were being built and they can still be built, along good old-fashioned husky methods and trimmed in modern settings. Bluefish is this sort of boat, just a good old-fashioned craft of the type that was popular ten years ago and of which many performing service today are as sound as the day they were built.

Hotei--A Family Boat (Pub. No. 5324)

by Hal Kelly

Here's a 23-ft. family boat with three bunks, two cockpits, all conveniences.

Hotei is 23 feet long with an 8-foot beam and every inch a family boat. Menfolk can ride in the forward cockpit where the helmsman has a clear view. Youngsters can sleep or amuse themselves safely in the large cabin which has 5-foot 11-inch headroom, bunks for three, galley and marine toilet. The gals can sun themselves in the roomy aft cockpit. All are well distributed, not crowded together near the stern. And with passenger weight shifted forward, Hotei levels off for speed under power of a Merc 800. The 80-hp motor drives her at 25 mph with six aboard! With only two aboard, Hotei does better than 27 mph and she gives a comfortable ride at this speed even in a three-foot chop. She also banks into a turn like a fine runabout--not digging in on the outside to throw passengers all over the boat like many a small cabin cruiser. Nor is she a wet boat We've been out in five-foot waves and stayed dry. A lot of thought went into storage space construction. There's a large compartment in the forward cockpit for charts and other items. The cabin has several shelves for small items and storage under the bunks for water skis, life jackets, etc. The aft cockpit has a 19x24-inch storage bin over six feet long that doubles as a seat. On each side of the motor well there's storage for battery, bumpers, line and spare props with six-gallon gas tanks below. The well itself is designed to take two Merc 800's or 500's if you wish and there's room for a 25-gallon long-cruise gas tank below it.

Perky--A Fast and Handsome 12-Footer (Pub. No. 5327)

by Henry Clark

Fast and handsome, this 12-footer proves the adage that good things come in small packages.

Luxury and looks on a low budget. That's the current commercial cry, and it applies perfectly to Perky. For a modest cost, the builder of this boat launches 12 ft. of style, utility and zip. Why 12 ft.? Well, we thought the 14 ft. Chipmunk was just right, but spacewise this 12-ft. hull is almost the same for much less effort and materials, along with the following advantages: Low cost of building; low cost 10 to 18 hp motor able to haul a skier slalom; uses smallest trailer built; easy into and out of water; a snap to drive, to beach, to dock, to store and maintain. Carries a family of five, with safe freeboard, wide beam, and soft ride. Long sweeping fins are not fins, but side panels, forming a built-in spray rail all around. Solid stock harpin eases forming the rounded bow, affording wide deck and smashes down the largest cruiser waves you can ram into. Simple plywood transom is edged with solid stock front and back, and braced with unique corner knees, another Clark gimmick to eliminate the chunky floor knee. Corner knees double as storage trays. Frame "ribs" are all straight stock, another Clark trick to ease building and still get an exacting bottom curvature for a soft ride. Ribs are easily assembled over the full size paper layouts. Stem is oak, shaped with plane, joined to forefoot with bolts. Forefoot lies right on keelson top. No notching. The gunnel, or sheer line is straight, making for a flat jig setup. Sheer line parallels keel.

Septa--A 12-Footer (Pub. No. 5331)

by Robert and George Schleier

This interesting 12-footer has a novel convertible top and foredeck anchor hatch.

Septa, the seventh boat built by this father-and-son team, is a 12-footer, with a 54-inch beam, having a foredeck with a hatch, a cross deck amidships and a novel convertible top. With an 18hp outboard motor she does a good 22 mph which is sufficient speed for skiing, not to mention getting to your favorite fishing grounds in a hurry. When the going is rough, her vee forward section cushions the impact, taking large waves without pounding. The flaring bow tends to make her a dry boat. She has simple, clean lines and her seaworthiness was proved to us during hurricane "Donna" when we found it necessary to buck the elements in her to get out and check the mooring lines on our 25-footer. The teeners like her because of her neat appearance, speed and her roominess which provides plenty of storage space for such gear as the necessary boat equipment, skis, scuba equipment, and, of course, there must be the radio and the refreshments. Three can comfortably seat themselves in the fore cockpit and have adequate protection from the elements or enjoy the cool shade under the convertible top.

Building the Cruiser Baby Betty II (Pub. No. 5334)

by Sydney M. Higgins

A completed detailed design, specifications, and building instructions for an attractive 42-foot vee bottom cruiser.

Baby Betty II is an enlargement and refinement of a Vee-Bottom cruiser designed some years ago, from which five known boats were built, with the idea in view of being purely a family boat which could be easily and cheaply built and at the same time have the required cruising radius, seaworthiness, and boaty appearance. It is an original design and has ben carefully worked out for the theoretical and technical data, such as stability, center of buoyancy, trim, etc., and the weights have been distributed os that the vessel will trim at its designed raft, as sown in the profile plan.

Comet--A 16-Ft. Runabout (Pub. No. 5336)

A fast 16-ft. runabout with plywood-plunked hull and inboard power, using a regular marine engine or a jeep conversion.

Modern in design and smooth in performance, this smart looking runabout will carry five passengers with speed and comfort, and yet be suitable for an occasional day of fishing or general utility use. The V-bottom hull is 16 ft. overall by 5½ ft. beam and has a forward cockpit seating two, an engine compartment amidships and an aft cockpit with room for three, plus space for fishing gear or supplies. Plywood planking makes the boat practically leakproof, light enough for trailer carrying and yet gives it ample strength to stand reasonably hard service.

Flyer--A 12-Ft. Outboard Utility (Pub. No. 5338)

A 12-ft. V-bottom outboard with simple, plywood hull that can be built as a decked-in sport runabout or open utility for fishing.

Double duty is the word for this fast outboard that combines the speed of a runabout with the carrying capacity and general all-around usefulness of a utility boat. A composite V-bottom hull with semi-convex bottom section and moulded non-tripping chines makes this combination possible. The simple, plywood construction produces an attractive boat that is light in weight, sturdy, and permanently leak-proof. If a hull of the double-cockpit type is desired, the regular construction procedure is followed, but when the boat is finished, deck beams are added and openings cut for cockpits. The deck is then covered with ¼ in. waterproof plywood. For utility use, a small outboard from 1 to 6 h. p. is recommended or an air-cooled inboard may be installed.

Flying Fisherman (Pub. No. 5341)

A fast, outboard utility. 11 1/2 feet overall, with an easily-driven bull, plunked with plywood or thin cedar.

Whether you like flashing speed or a leisurely trolling pace, this all-around utility boat will fill the bill. With one of the big twenties hung on the transom, she’ll plane smoothly along at high speed and give you all the thrills of riding in a regular speedboat. Or, if you’re one of Izaak Walton’s followers and prefer a more leisurely speed, a lightweight outboard kicker will still get you and a friend or two, plus all your gear, to your favorite fishing grounds in good time. The versatile hull is soft-riding, turns on the proverbial dime and because of its size and light weight will ride on top of your car. Although it was designed for regular plywood planking, you can use thin cedar stock, backed up with seam battens and canvas covered.

Eclipse, A Hand 40-foot Express Cruiser (Pub. No. 5343)

Designed by William H. Hand Jr.

Now all you speed motor boatmen, here is your chance. The variety of boats for which we are publishing the plans is complete. We have had little boats, big boats, runabouts, cruisers, and auxiliaries. Here is a brand new one. Eclipse is an express cruiser of the utmost refinement and most up-to-the-minute features. In 40 feet of length Mr. Hand has succeeded in securing every desirable advantage of the much larger boats. Complete accommodations are provided for cruising with four or more persons and the necessary facilities are ample to care for the full personnel with every comfort. This boat follows along the lines developed by the famous express cruiser Flyaway III. This cruiser established many enviable records in competitions of all sorts. Long-distance races had no terrors for it. Inland waters, or the open Atlantic, it was all the same. Flyaway was always on deck and most generally the first to finish. Our cruiser this month follows the conventional V-bottom practice developed by Mr. Hand. The sections have been designed to give the maximum of speed and seaworthiness for the minimum power installed. Working on the theory that the outside deck and cockpit space is the portion of the boat which the majority of boatmen use the most, this design has been particularly developed to allow the utmost possible outdoor space. The interior has not been neglected, however, in order to accomplish this. The arrangement inside is as follows: Storage for lines and deck gear is arranged in the forepeak. A roomy lavatory comes next with a pair of good sizable wardrobe closets close by. The cabin proper is fitted with a pair of sliding transom berths which afford ample sleeping accommodation. Some more closets are provided just adjacent to the galley compartment. This is completely equipped with stove, refrigerator, sink, dishracks and all necessary fittings. The motor selected for this boat is a model F. S. six-cylinder Sterling which is compactly installed under the bridge-deck floor and just aft of the aftercabin bulkhead. Plenty of room is provided on all sides in order to allow of easy access to all parts of the motor and also to give it some breathing space. A motor which is hidden away in an inaccessible corner is neglected and when it is treated this way its usefulness is soon impaired or destroyed altogether. Roomy seats are provided on each side of the bridge-deck space for the operator and some guests to remain comfortably seated while the boat is under way, and a further seat the full width of the after end of the cockpit makes an ideal place to sit and snooze while the boat drives along at a merry clip.

This Is What Mr. Hand Says About Eclipse

Here is a safe, sane, and wholesome motor cruiser of a type which has been developed to a high degree of efficiency, and is exceedingly popular. The predecessor of this V-Bottom is the old “Flyaway Ill,” probably the first real express cruiser, and a boat responsible for a marked change in the development of the express cruiser type. The arrangement is one which seems to use the space to beet advantage. The cabin provides sleeping accommodations for four with adequate toilet and galley. The cockpit is large, and there is, plenty of deck space. The average motor boat user spends at least 75 per cent. of total time on board in cockpit or on deck, therefore, it is believed that sufficient deck space and cockpit room is quite as desirable as the maximum sleeping accommodations, something which is frequently overlooked in planning small cruisers. With the power plant designated, this little cruiser will maintain a speed in excess of twenty miles, and be able to go anywhere along the coast In the summer months quite as safely, and far faster, than the average boat.--WM. H. HAND, JR.

Handy Andy--A 13-Ft. Power Scow (Pub. No. 5345)

by Hi Sibley

An inexpensive 13-ft. power scow with an air-cooled engine: for hunting, fishing or use as a workboat.

Designed to take any one of the low priced, air-cooled engines that are on the market today, this husky scow is about the cheapest and most practical form of power craft that you can build. An though she's no beauty for appearance, there's a world of utility packed in her snub-nosed hull. If you're interested in low cost transportation for fishing, and want to take along a friend and all your gear, Handy Andy is the answer. On the other hand, if pintails or greenheads are your game, you'll find the 12-in. draft of the scow ideal for poking about in marshes and the shallow waters where ducks feed. And last but not least, if you work for a living on or about the water, you'll find a dozen different uses for the scow, such as clamming, tending lobster pots, hauling supplies and towing larger craft in a boat yard or yacht club.

Snuffy--A 12-Ft. Utility Boat (Pub. No. 5347)

A 12-ft. utility craft that’s light enough for one man to lift yet ruggedly built for rough going. The simple plywood hull is leakproof and requires little upkeep.

If you've got a car and live within driving range of a lake or river, then Snuffy will solve the problem of having a boat for fishing or camping trips without paying costly mooring or storage rates. Because she’s light in weight, you can get her on the roof of your car without a lot of fancy tackle and with the outboard tucked away in the trunk, take off for your favorite spot. For her compact size, the boat has a surprising amount of room and even with a full load aboard, is easily rowed or driven by any small outboard from 1 to 10 hp.
