Water-Wagon--A 20-Ft. Outboard Houseboat (Pub. No. 5238)

"Water Wagon" is the first member of a new family of boats designed to appeal to outdoorsmen everywhere. She combines the best features of a fishing cruiser, house trailer, hunting lodge, family picnic boat, and exploration vessel. As a boat, she is surprisingly seaworthy. Her 51/2-in. draft will enable you to explore behind islands and in coves no other boat can reach. You can go right across sand bars, thus sometimes cutting in half the running time on a trip. Adequate speed is provided by one or two outboard motors. With the remote motor controls now available, one person can handle "Water Wagon"; but she’s fun to run even if you don’t have remote controls—simply use a seagoing bell system and have one person in the bow to act as pilot and another in the stern as engineer. Elimination of bilges allows 6 ft. 6 in. headroom. Two people can sleep in the cabin. Hinged upper berths could be added to accommodate two more. On the house top, two more can bunk down on the utility box and still two more can sleep on folding cots. A well-appointed toilet room and an enclosed shower add luxury to utility. For lovers of the rod and reel who can’t take the sun, the wheel wells can be used as inside fishing wells. Included in the accommodations are a comfortable dinette and a galley that has running water, a gas stove, and a 50-lb. icebox.

Vixen--A 21-Ft. Runabout (Pub. No. 5243)

by George E. Meese

Here’s a craft with an underwater form specially designed to move at almost PT boat speeds, whether the water is smooth or choppy.

Were you ever out boating with some friends when a runabout slipped past causing everyone aboard your boat to remark about its speed? After a few words along that line, one of the supposedly water-wise characters comes up with the sour-grapes remark, “Yeh, but he can only do that on smooth water!” That remark might have been true in the past. However, naval architectural research has developed an underwater form that will give a high smooth-water speed and still allow the boat to be pushed at nearly those same speeds in rough water. "Vixen" was developed from these lines in order to give maximum performance in both smooth and rought water, and still be easy enough to build by the amateur.

Lily Pad--A 16.5-Ft. Outboard Cruiser (Pub. No. 5246)

by A. Mason.

Specially designed for amateur builders, this boat is suitable for an occasional overnight cruise and will do 18 mph on 22-horsepower.

“Lily Pad” is intended for those amateur builders having only a fair knowledge of woodworking tools and who want a safe boat that they can successfully complete without expending too much time and effort. While the hull form of a squarebottom scow permits the most simple type of construction, this form does not keep out spray when waters are choppy, and consequently the modified scow hull form of "Lily Pad" has flaring sides to partially overcome this fault. Also to simplify construction the bottom has no deadrise to facilitate the use of athwartship planking, but "Lily Pad" may have a slight tendency to pound as she is not intended for shallow waters. However, this tendency has also been somewhat alleviated by having the bow cut away so that it can be run right up to steep banks and permit passengers to step ashore dry-shod. This eliminates any need of a dinghy. However it must never be thought that "Lily Pad" is intended only for calm quiet waters since she will be as safe and seaworthy as the majority of other small boats intended for semi-sheltered waters.

Waterman--A 19-Ft. Heavy-Duty Outboard Cruiser (Pub. No. 5247)

by H. I. Chapelle

No playboy, this cruiser can be utilized for fishing, lobstering, etc. With moderate power, she will do up to 12 knots economically.

This boat is intended for use in open waters where a small boat must meet both sea and wind. She is intended for moderate power to give economical operation at those speeds usually associated with cruising, say up to 12 knots; it is unfortunately true that a boat capable of performing well at high speeds with great power does not perform economically at low speeds with either small or large power. “Waterman,” then, is a cruising boat as far as speed is concerned. The lift-top cabin has two advantages; it gives a low superstructure but allows useful headroom in the cuddy when at anchor. The deck box forward of the trunk is for anchor gear which is more readily stowed in the deck box than passed below deck in so small a boat. The cockpit has been made as large as possible and if this were covered with an awning or cockpit-tent, with the lift-top cabin in use, the cockpit is converted into usable “cabin space.” The cockpit seats may be made as lockers for supplies, fuel, etc.; the engine when not used can be stowed in one of the seat lockers aft or, if too bulky for this, in the cabin. The hull form follows rather closely one that has been popular in some of the workboat launches on the Chesapeake; it is basically a “modified sharpie” in which the chines and rabbet meet at the heel of the stem. This allows a V-bottom to be used without the difficulties in construction caused by the use of the common V-bottom forefoot.

Heron (Pub. No. 5248)

by Wm. Garden, Naval Architect

The first little cruiser constructed from this model is owned by Dr. Russell Jackson of Anchorage, Alaska. Anchorage is situated on Coon Inlet, a body of water well known for excellent fishing. A shallow-draft yet seaworthy boat was needed, for the Inlet has miles of shoals and terrific tidal currents, rips, and over-falls. Since Heron was designed to be a backyard project, construction has been kept simple.

Sea Craft-A 25-Ft. Cabin Cruiser (Pub. No. 5250)

Ideal for use on large lakes or rivers, and fully seaworthy for offshore ocean cruising, “Sea Craft” is a smart cabin cruiser designed with an eye toward simple, low-cost construction for the inexperienced boatbuilder. During World War II, the original boat was given severe tests for seaworthiness when it was used by the United States Coast Guard to take highranking officers from ship to shore. The boat has an over-all length of 24 ft., 71/2 in., and a breadth at sheer of 7 ft., 81/2 in. A converted Chrysler “75” auto engine easily pushed it along at a cruising speed of 15 knots. However, any marine or converted auto engine of similar horsepdwer may be used. Although this article describes the building of a sedan cruiser, this particular hull, with a few changes in the cabin construction, is readily adaptable to a sport fisher, express cruiser or utility boat. The cabin design of "Sea Craft" was selected because it offers one of the best all-around accommodations. Its open cockpit is large enough for fishing, lounging or sun bathing and the roomy cabin provides comfortable living quarters on a long cruise. It is equipped with a fresh-water tank, sink, cooking stove, toilet and two bunks. Two additional upper bunks can be fitted to sleep a total of four. In addition, there is plenty of cabinet and stowage space for gear.

Sea Jet--A Hickman Sea Sled Type (Pub. No. 5253)

Designed by William Jackson

Any number of control and seating arrangements are possible with this spacious 17-footer whose design stems from the old familiar Hickman Sea Sled.

"Sea Jet" is an “inverted vee” runabout based on the highly successful Hickman Sea Sled principle. The tunnel formed by the inverted vee funnels air under the hull to provide extra lift, while reducing wetted surface and its resultant drag. Extra stability, a softer ride, and greater load-carrying capacity are also benefits claimed for this type of design. While construction of "Sea Jet" is relatively simple, it is not recommended as a project for the beginner, due to its compound bottom structure.

Float-A-Home--A 21-Ft Houseboat (Pub. No. 5254)

Designed by~Ernst Lanzendorfer

A luxurious 21-footer, this houseboat is very stable, relatively easy to build and interior arrangement can be varied to suit your needs.

A Houseboat is a unique water craft in that it combines most of the comforts of home with the mobility of a boat. Of course, use is limited to sheltered waters, and speeds are slow in comparison to more seaworthy vessels. "Float-A-Home" is a 21-footer that provides plenty of living space for three or four persons. An extremely simple houseboat to build, it features a strong hull with a heavy keel and close-spaced framing. This, coupled with a relatively low profile, makes it a very stable craft. Features include a conning room designed to provide an unobstructed view forward and to the sides through glare-proof, swing-away windows. The settee behind the helm extends to make a full length berth, and in the main cabin, steps at the companionway can be removed to make way for a fold-away berth. Of course, the entire interior arrangement can be worked out to best suit your individual needs. Shown is an arrangement where a section of the after deck is left open to provide a patio effect on the starboard side, while the galley is to port.

Robin--A 12-Ft Utility Boat (Pub. No. 5255)

Designed by William Jackson

A 12-foot utility, it can play many roles, and very well indeed. Power by a small outboard motor, it moves along briskly.

"Robin" is a 12-foot utility runabout that’s suitable for use as a hunting and fishing skiff, yacht club tender, or work boat. An extremely simple boat to build, it is rugged, and will step along nicely with motors in the 7- to 10-hp range.

Skeeto--A Ski Boat (Pub. No. 5256)

Designed by William Jackson

Water-Ski enthusiasts, who rate their pleasure in mph, learned early that towing skiers behind an ordinary runabout is something like running the family jalopy in a sports car race. Their next step was to design a craft especially suited for their use and that’s how SK runabouts came to be. The first requirement was that SK’s be able to convert hp to mph in a way that runabouts never learned to do. Secondly, they had to be able to take the beating a ski-tow boat regularly gets, and, of course, the SK had to have clean lines, safety, and comfort.

Playboy (Pub. No. 5260)

You can build this high styled and speedy planing outboard runabout.

Sharp! Styled like a sporty inboard—that’s "Playboy". >From her wrap-around spray rails to the walk-through entrance to the forward cockpit, Playboy simply shouts class. With a 25-horse outboard, "Playboy" will step around lively at 32 mph. Extras include a “glove compartment” for fishing gear, charts, odds and ends, smooth floor to save scrambling over frames and mahogany planking and deck. Ideal for sports, "Playboy" packs plenty of power for skidding aquaplanes or water skis or hauls up to six persons—seated. Even with the convex bottom, you can plank Playboy with plywood sheets that keep it dry and take all the punishment a fast ride on a choppy lake can dish out.

Sea Gal (Pub. No. 5266)

by William D. Jackson, Naval Architect

Tradition has it that it’s the strong, broad-beamed heavyweights who are more stable when the going gets rough. Sea Gal’s ample beam and 300 lb. weight make her ideal for the rough waters along the east or west coasts, the Gu1f or inland lakes. With a 14 hp Evinrude, this versatile utility outboard boat will, do 25 mph with one aboard and plane with 3 persons aboard. That reserve stability and safety, built into the "Sea Gal" depend in part on how well you build her. If you use good white oak framing, exterior A-A plywood sheathing, and,, after it’s finished, coat the entire hull with two coats of Kuhl’s Three Way Preservative, this fine hull will serve you for many years to come. "Sea Gal" uses the minimum number of both transverse and longitudina1 framing members but they must be somewhat heavier than the type used on planked boats whose closely spaced frames prevent the plank edges from flexing.

Fire Ball's a Funster (Pub. No. 5267)

by William D. Jackson, Naval Architect.

Here are complete plans for building a high speed sportster.

"Fire Ball" is a streamlined speedster that seats 4 or 5 passengers and can use outboard motors of from 10 to 50 hp. Exterior waterproof plywood is used throughout to produce a sturdy craft in a minimum of time. Cost of construction will vary but should be reasonable. If well built, completed value should be much greater than the cost of the material

Ideal Scooter for Hire (Pub. No. 5271)

by William D. Jackson, Naval Architect

There's good money to be made in the renting of boats, providing you own the type of boat that meets the needs of a majority of the boating public. Here is a sturdy, dependable livery scooter that’s ideal for fishermen and small family outings. It can be powered by a small, air-cooled inboard motor such as the 1¾ or 2 hp U.S. Motors Corp., Clinton, Briggs, etc.) which costs little and will operate all day long at 5 to 10 mph on a minimum of fuel. You’ll find that a fleet of these serviceable scooters is easy to build and may provide you with a profitable boat rental business. In constructing this scooter, if you keep plywood patterns of everything, you can use them over again to help you build as many of these boats as you think youcan use.

Ranger (Pub. No. 5272)

by William D. Jackson, Naval Architect

All the facilities you need are wrapped up in this 17-ft. outboard cruiser.

When powered with larger outboard motors such as the Johnson 25 or the 33 or 50 hp Evinrude, "Ranger" will plane at speeds of 20 to 35 mph. She’s easy on fuel and maintenance costs, too, and you can transport her most anywhere by trailer. Run the trailer into the water to float the boat and you’re on your way up your favorite waterway. Two persons may sleep aboard and there is room for a small stove and a few pots and pans with which to fry those fresh fish. Although a bandsaw will help when sawing out such parts as the stem and an electric drill will speed up the job of fastening the "Ranger" can be constructed with ordinary hand tools.

Buzz (Pub. No. 5275)

by William D. Jackson, N.A.

"Buzz" is a versatile, planing outboard runabout measuring 11 ft. in length with a beam of almost 56 in. It is lightweight with strong and sturdy constructional features, seats four passengers and uses such outboard motors as the Evinrude 9.7 hp; Johnson 9.9 hp, and the Mercury 10 hp. "Buzz" will plane a remarkable load at high speeds, equaling other boats with twice the hp. It also maneuvers well in rough or smooth water, making turns easily at wide open speeds. As a lightweight, portable boat "Buzz" may be loaded atop any auto for sport trips. The same building forms you make for "Buzz" may be used repeatedly to construct one or one hundred replicas of "Buzz" so that an individual, in one community can furnish the form for any number of these boats or an individual builder may construct as many boats as he can take orders for and make.

Chug-A-Tug--A 21-Ft Little Ship (Pub. No. 5286)

by Donald LI. Smith, N. A.

This 21’ cruiser is a “little ship” with jaunty tugboat lines.

The roving nautical eye will be sure to catch the tug-like silhouette of "Chug-a-Tug" against any waterway backdrop, for here indeed is a most unusual small boat profile. To those who have always hankered for the feel of a real ship, "Chug-a-Tug" is the next best thing. When you step into the wheelhouse, start the engine, grasp the spoked mahogany ship’s wheel, and give a blast on the air horn to get under way, a new dimension in pleasure boating is suddenly presented. An excellent vantage point is provided the helm by virtue of the forward location and large open pilot house. A glance toward the stern reveals a sizable portion of the craft aft of the helm and as the wheel is turned, a quaint feeling of moving a larger vessel accompanies the visual aspects of a swinging stern as the craft comes around. Heading up to a dock is a dream, and there is positive vision right up to contact with a pier, when you can reach out from the pilot house to “fend off” or handle lines. The forward cockpit is, in itself, a real pleasure for up here there is only the sound of bow waves and a gentle throb from the engine exhaust astern. Sunning, fishing, or lazy cruising can be yours with "Chug-a-Tug". Her walk-around decks and two cockpits afford luxuries not often found in craft this size. Anglers who prefer still fishing or casting can appreciate being able to move around the open decks, with protection in the cockpits or as provided by the handsome bulwarks. No tackle boxes lost overboard or getting fouled up in a companion’s gear, because of sharing cockpit space. In this sense "Chug-a-Tug’s" two cockpits give her a quality of being almost two boats in one. With two berths, a galley, and a head, she is a real cruiser throughout.

Sunbeam--An 11 Ft Outboard Runabout (Pub. No. 5290)

by Edwin Monk, N. A.

Here’s 11 ft..3 inches of beamy, easy-to-build boating pleasure.

Making a full-sized drawing of each frame simplifies building the skeleton of your boat. You can use one of the fir plywood panels ordered for planking as a layout board, with a long edge of the panel serving as a baseline. Lay out a centerline at right angles to this edge with a large steel square, and plot the water line, setup line and buttocks as shown in the plan.  If you number each drawing to avoid confusion, you can superimpose all frame layouts on this one set of reference lines.
