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.

Building Roamer and Rambler (Pub. No. 4904)

With any of the larger motors, this 733-lb. hull which is 51/2 ft. wide and a full 16 ft. long, will average 26 miles per hour, while giving you maximum safety and comfort. Dry, safe, fast and comfortable—what more, with the tang of the sea and a blue sky, could any man desire? "Roamer" is worth building well; and it has been especially written in simplified form so that you can build it well in six to eight weeks time without hurried, slipshod workmanship, although the time required for building will, of course, depend largely upon your own skill and the number of working hours each day.


RAMBLER: An Inboard Runabout

(Uses the same hull as the small cruiser, Roamer)

Rambler! And she does just that—rambles! With a light four of about 40 H. P. doing 283100 r.p.m., this variation of the “Roamer” hull will scud along at 26-8 miles per hour with a load of three passengers. Moreover, the generous freeboard overall, and the pronounced flair to the forward sections makes the boat safe and dry in any kind of seaway. “Rambler” is a double-cockpit affair, with each seat easily accommodating three passengers. The motor is under a hatch between the two while the gas supply is fed from the rear of the boat. All controls are of the positive rod type, but simpler installations can be effected if expense and labor are an important consideration.  Building the hull for this craft is much the same as building the hull for “Roamer”—the same number of frames and the same dimensions are used, the keel is the same, the stem is a duplicate—the whole construction work up to and including part of the decking can be taken from the “Roamer” description. The only difference is that the transom board can be left vertical if desired, instead of being raked as is necessary for the outboard job. (We have combined both booklets into one Handi-Book since they use the same hull. Individual booklets are still available).

Falcon--A trim Strudy 18 ft Inboard (Pub. No. 4909)

by Don B. Pederson

A Trim and Sturdy Inboard Runabout

Incorporating the latest developments in boat construction and eliminating many problems which usually confront the average, novice in boat building, “Falcon” is an all-around utilify runabout which can be transformed easily into a sleek cabin .cruiser if desired. The cost of building the original boat as a runabout was $125 at Newport Beach, Calif. The hull is adapted for use of almost any marine engine from 5 to 20 hp. Total depth .16 in., beam 66 in., draft 42 in., passengers 7 or 8 and speed 17 m.p.h. with a 20 hp. motor. The boat planes at 7 m.p.h.

Fisherman (Pub. No. 7003)

by Charles Bell

LOA 12', BEAM 5'

Fisherman was designed with one purpose in mind—fishing.

Although she has a planing type bottom, she is not intended for high-horsepower motors—10 to 15 will do nicely and some of you, undoubtedly, will use a 20. Only 12 feet in length but of good beam, she will be easy to get in and out of the water and will be comfortable to work a line in, in most sheltered lakes and rivers—no rapids, please; leave those to the professional stunt men and the boats designed for them.

Mackerel--A 16-Foot Family Type Outboard Runabout (Pub. No. 7050)

Designed by Charles G. MacGregor

LOA 15 ft. 8 in., BEAM 4 ft. 3 in., DEPTH 1 ft. 11 in.

This is a design of a popular type of small family runabout, using any one of the small outboard motors from about 6 hp, up to 10 hp. This little craft will carry as many as eight passengers, and if not overloaded will attain speeds up to 15    m.p.h., depending on the power used. By making slight alterations to the hull-structure a small air-cooled inboard motor can be used. Waterproof plywood is used throughout where possible and feasible. Panels can be obtained -in 16' lengths without a splice or butt, and this is recommended. However, if these panels are not readily available in your locality, do not hesitate to use shorter lengths and make a butt.

Pioneer (Pub. No. 7052)

Designed by Charles MacGregor

LOA 15 ft., 6 in., BEAM, 5 ft. 7 1/2 in., Draft 1 ft. 4 in.

The possibilities of the trailer-cruiser as a companion to the automobile in opening up more extensive cruising vistas to the man of average means will be more and more apparent as time goes on. The remarkably enthusiastic reception given to resin bonded plywood boats by the boating public in the last few years will go far toward making this possible. We can now build stronger, lighter and in many ways better boats than was possible by the old-fashioned conventional method. We have at hand new material and methods of building small boats, scorned by some old time builders but readily accepted and adopted by the more progressive and younger element of far-seeing builders. Further than this, the construction can be made so simple as to make it possible far the home builder to construct his own boat without any previous experience as a boat builder. It is possible for him to butld a small floating home, one that can be stored in a garage, hauled overland on a trailer to practically any part of the continent over our splendid system of highways; then from a chosen point launch this little cruiser and explore rivers, and-bays hitherto inaccessible. We will then have for such summer cruising the coast of Maine, the St. Lawrence River, the Thousand Islands, Georgian Bay Bay and its 30,000 islands (a cruising paradise) Muskoka Lakes, the Minnesota lakes, Mississippi River, Florida and the inland waterways route and the new huge man-made lakes formed by the dam projects in the west. It is with all this in mind that I have prepared this design. It is one that can be built by an owner-builder and that will he capable of carrying him safely on many happy and delightful cruises in unexplored territory. This boat which I have chosen to call Pioneer is built of waterproof plywood where practicable. As an open launch it is roomy, strong, yet light enough to be handled on a trailer. It will be very suitable for use as a fishing boat or for a party of about six persona for day cruising. The form is such that it can be easily and economically driven at speeds up to seven miles an hour with either a small outboard motor or one of the many air-cooled or water-cooled inboard motors now on the market at very moderate prices.

Crawfish--A Tunnel Stern Motorboat (Pub. No. 7056)

Designed by Wifliam F. Crosby

LOA 15 ft. 6 in., BEAM 4 ft. 8 in., DRAFT 4 ft. 1/2 in.

The little boat shown here is designed for protected waters where the bottom is close to the top. The draft figure includes the rudder and propeller.
As you can easily see she is a tunnel stern boat equipped with a little marine engine not to exceed 4 hp, at the outside. The engine shown is only 21/2 hp. She is not built for speed as no tunnel stern boat can be driven at high speed. Being a flat bottom type, she is not meant to go to sea in either. She would make an ideal fishing boat for some shallow pond or lake. She should weigh a little over 600 pounds complete with engine, propeller, etc. The weights of engine, tanks, seats, etc., should be placed in the hull as shown in order to have her trim properly. The tunnel for the propeller is large enough to take any wheel up to twelve inches in diameter--which is more than ample. The angle up to the top of the propeller and down to the stern should be as shown. Do not make the mistake of running the tunnel directly out to the stern even with the highest point of the tunnel. If you do, it will not pick up the water and your propeller will be revolving mostly in air. The construction offers wide possibilities in choice of materials: The materials specified are those most suited. Others may be used but don't try to use a soft wood such as redwood and expect fastenings to stay in it. Plywood; (waterproof) may be used almost throughout with the exception of frames and the bed pieces to which the engine is actually, mounted. If you use waterproof plywood, you can reduce the thickness by about one-half from the material specified as it is at least 40 per cent stronger than ordinary wood.

Skua--An 8-Foot All Plywood Outboard Skimmer (Pub. No. 7061)

Designed by Charles G. MacGregor

LOA 7 ft. 9 in., BEAM 3 ft. 10 in.

To those who love the thrills of speed on water we submit here a small outboard skimmer which if carefully built will give her owner a great deal of pleasure. There is a splendid choice of suitable outboard engines developing 3 to 30 hp. Most of these motors run efficiently at speeds between 3,500 and 4,000 r.p.m. and as high as 5,000. It is not necessary to use a steering wheel but it is a great convenience. Keep the tiller lines well clear of the open cockpit so that they will not be in the way when turning from cranking to steering position. The seat should be arranged to suit your own needs or eliminated

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.
