Sandpiper--A 22-Foot Shoal Draft Runabout (Pub. No. 5424)

An attractive design and specifications for a shallow water craft of excellent appearance and a fine turn of speed

Designed by Chester A. Nedwidek

Sandpiper is a double cockpit runabout of the V bottom type, designed with a tunnel stern, this being done to cut down the draft so that she can be used in places where the water is plentiful but spread out over a large area. The extreme draft to the bottom of the wheel is only about eighteen inches. If a heavier engine using a larger wheel is installed the draft will be increased slightly. The engine shown on the drawings is a 35-50 horsepower Kermath weighing about 700 pounds, which should drive Sandpiper at a rate of about 22 to 25 miles per hour. Sandpiper will carry about six people very nicely although her seating accommodations allow for more. She is handled entirely from the forward cockpit, here the helmsman will sit at his steering wheel, with the reverse lever and all other necessary items for the control of the boat near him. This double cockpit arrangement makes this boat ideal for a yacht tender as then the crew is kept separate from the guests or the owner as the case may be. With the decks painted green, which by the way is much easier on the eyes in the sun than if painted the usual buff color, mahogany transom, mahogany covering boards in the way of the after cockpit, mahogany top strake and the rest of the topsides painted white, with a green boot top, you should have avery handsome job.

Shark--A Deep Water Runabout (Pub. No. 5425)

A substantial design and building description for a heavy duty runabout able to go out to sea with ease

Designed by Chester A. Nedwidek

This runabout which was designed for real service such as fishing in open waters.  From her lines it will be seen than she has plenty of displacement and is not just sitting on top of the water as the usual speed type of runabouts are. Straight V sections to simplify the building as much as possible and plenty of freeboard to make her a good seaboat. The plans of Shark show a boat that is twenty-three feet over-all, twenty-two feet one and three-quarters inches water line, six feet six inches beam and two feet draft. The lower sheer line is a straight line running from a height at the stem of twenty-seven inches above the designed load water line to a height of twenty-one inches at the transom, the upper sheer is comprised of two straight lines, with a break at station 10, the upper plank between these sheer lines if made of mahogany and finished bright will give a very snappy appearance to the entire job, the sheer moulding should also be of mahogany.

Compact--An Outboard Cruiser (Pub. No. 5426)

A smart little boat designed for economical driving with the popular outboards for a power plant

Designed by C. A. Nedwidek

Compact in name and compact in reality, is this little raised deck cruiser, the plans of which are shown herewith. Twenty-five feet in overall length and every inch of these twenty-five feet is used for some practical purpose. Designed with the idea in view to give the utmost in a boat for a small outlay, she has also been kept to a simple type of construction for the amateur to build himself. In the forward cockpit we have something novel but not new, this makes an ideal place to sit and sun oneself, the forward cockpit idea has worked out real well on larger boats and there should be no reason that it will not work as well on a small boat. Access to the cockpit is gained by going over the raised deck, but if a hatch is desired one can be easily fitted, in fitting a hatch one can make the back of the seat in the forward cockpit to hinge down, then one can get to the cockpit from the interior of the boat. For the arrangement of the boat we have the cabin with two transom seats which are to be made so that they extend to give a good width for use as berths, the extension idea was used so that when the seats were not being used as berths more floor space will be available and a table can be used in the cabin. On the port side is the toilet room, to be equipped with a small corner wash basin and a toilet. The basin is to be equipped with a pump and piped up to the fresh water tank. Opposite the lavatory on the starboard side is a space laid out for a galley, dish lockers, dresser with ice chest under, sink fitted in dresser top, sink also to be fitted with a pump for fresh water, an d a space for a single burner kerosene or alcohol stove, of a type that is generally used for camping. If this is not desired a Sterno stove might do for the purpose.

Sturdy--A Utility Boat (Pub. No. 5427)

Designs and specifications for a most useful type of small boat intended for many kinds of useful service

Designed by C.A. Nedwidek

This is a small round bilge boat primarily intended to be used as a general service boat. She also would make an ideal club tender, for with the small cuddy house shown aft, she would afford shelter for passengers in inclement weather. She has not been designed with speed or fancy finish in mind, just a plain little real boat. Her general layout and arrangement consists of a short forward deck under which is a general stowage locker, for anchors, chains, ropes, lights, etc. Next we have a large open cockpit with full length seats on each side. The steering wheel is located at the forward end as shown. All engine controls shou1d be brought to the wheel, to make her easily handled. Two gasoline tanks, rectangular in shape and of a size as shown on the plans are to be installed under the seats one on each side as shown. Aft of this cockpit we have a small cuddy house, which houses the engine and is also fitted with two seats, one on each side. Then there is a good after deck. Two Sampson posts are shown, one fitted forward and one aft. These can be used for towing purposes.

Ethel--A 27-Foot Trunk Cabin Cruiser (Pub. No. 5428)

by Chester A. Nedwidek

The design for the cruiser "Ethel" is approaching the class of work which will require a pretty experienced amateur builder with a good shop. It is not recommended that amateur builders without previous experience at boat building attempt to build this cruiser, for they will find its construction more difficult than their experience and facilities will allow. A job like this is really more than a one-man job, so that if you decide to build the boat yourself, make certain that you have plenty of willing help, otherwise you may find that you are still working on the boat next summer.

Shallow Draft Cruiser, Turtle, The (Pub. No. 5429)

Designed by Chester A. Nedwidek

Attractive design for a little boat designed particularly for amateur boat builders and arranged to accommodate several persons

Turtle, a smart little Cruiser, designed for service in very shallow water, will make an ideal boat for exploring creeks and shallow rivers. As designed she can accommodate two people on the berths in the cabin, as the hull is sheathed in the back of the berths no uppers are provided for; if wanted these can easily be installed, giving her sleeping accommodations for four instead of two. The forward cockpit is an ideal place to sit and enjoy the scenery while cruising up some winding creek, when one never knows what view will greet the eye next. In regard to the design of the hull this has been kept as simple as possible, vee bottom, the sides have been given a little shape that is a flare forward and tumblehome aft to take away some of the boxy look that a straight section boat would have.

Janet--A Double-Cabin Cruiser (Pub. No. 5430)

Designed by C. A. Nedwidek

Small cruising craft of popular type, completely designed and described, ready to begin construction

Several years ago I was commissioned to design a thirty-six-foot double cabin cruiser with a center cockpit. This design proved very popular and the owner of this particular boat was very well pleased with the layout; it proved very comfortable and convenient. Knowing this and feeling that a boat designed along her ideas might prove popular, I proceeded to design the boat shown here. Six feet were cut off of the length, but still leaving a boat that should prove roomy enough for the average man and still small enough for him to handle and keep up. One other item was changed, the original design was of the round bilge type while this is of the V bottom.

Magnet, A Hand 28-foot Cruiser (Pub. No. 5431)

Designed by Wm. H. Hand, Jr.

All aboard! Now that vacation time is here and, rapidly becoming, a memory, it is well for those of us who had to sit on the club porch and watch the other fellow have the good times to consider plans for a boat of our own. This series of plans from the drawing-boards of Wm. H. Hand, Jr., are designed with the particular object in view of encouraging those of us who wish to own a boat to undertake its construction from well-studied and properly executed designs. The proper design of a boat is more than half of its future success. Stand on the banks of any river in the country and watch the procession of boats as they pass. How many of these were sponsored by a competent designer. One can tell without a second glance all those that were just built by hit-and-miss methods. Notice the difference when a properly designed and kept boat appears. Everything is in its proper place, and where it was intended to go by its designer. The engine is located so that the boat trims properly. She is not down by the head, neither does the bow aim at the sky; rather, the trim is properly proportioned so that the boat is correct in all particulars. The arrangement of the boat is in general similar to other small boats of this type. A pair of transom berths forward, with the customary galley and ice-box amidships, followed by the motor under a raised cockpit floor just aft of the cabin bulkhead. The cockpit is roomy and of ample size. The seats have been purposely omitted in order that more comfortable wicker chairs or furniture of a like nature might be used here. For the amateur builder this should be an easy boat to construct.

For the man with moderate means who desires a smart up-to-date cruiser that will give a good account of itself in rough or smooth water, this design should make a favorable impression. There is ample cockpit room for day trips and comfortable cabin accommodations for a small party while cruising. The power plant designated, though small, should drive this little cruiser better than 13 m.p.h. Simplicity is the keynote of this design as noted by the absence of doors,small useless cupboards, etc., that usually hamper the elbow room in a boat of this size.--WM. H. HAND. JR.

Broad Bill--A Sword Fisherman (Pub. No. 5432)

Designed by C. A. Nedwidek

Complete plans and specifications for the construction of a typical and popular craft among new england fishermen.

Broadbill has been designed for the Yachtsman who has had a taste of that sport of sports, Swordfishing, and who now wants to try his skill with his own boat. In size and type she is typical of the boats fishing out of Block Island. The layout is slightly different in that the motor has not been put in the cabin but occupies the space generally used for hold space. The cabin is small but ample, having two hinged pipe berths, Shipmate stove, sink, ice box, and toilet. Also, a clothes locker at the forward end with the rope locker in the bow. A small pilot house over the companionway with steering wheel, and compass shelf, provides protection for the helmsman in bad weather. The fish well is aft of the motor with a flush hatch on deck. The 100 horsepower motor will give Broadbill a little more speed than the average boat of her size and type and the 220 gallons of gas will give her ample cruising radius. The construction has been kept simple and the amateur should not find any great difficulty in building her.

Comfort--A Scow Houseboat (Pub. No. 5433)

by C. A. Nedwidek

Design and building instructions for a popular type craft adapted to summer service and arranged to accommodate the entire family with a few guests   

Comfort, according to some may not be what they would call a boat, in one sense of the word she is not, bu~ she is a comfortable floating home, one, that if one should by any chance get tired of the scenery or locality can be moved to another. The actual construction of this scow houseboat is simple. No line to be laid down and faired up, as would be necessary on any other type of boat. Just straight away simple work, all square joints. With the possible exception of the hull itself the rest of the work is about the same as would be encountered in building a small frame house. If this job is tackled by the amateur boatbuildei the biggest problem he wifl be up against is to find a place~to build. This should be as near the water as possible for when completed it will be a very heavy and cumbersome craft to handle, particularly out of water.

Shark, A Hand 21-foot Utility Runabout (Pub. No. 5434)

Designed by Wm. H. Hand, Jr.

The last runabout in the series of Hand plans is presented herewith. Only twenty-one feet long but combining in a small space all of the conveniences and utility of a larger boat. The arrangement is well planned and provides a pair of individual seats forward at the steering position. Additional seats in the after end of the cockpit will accommodate five or six more people and adapt the boat to ferry service and other utilitarian purposes. The motive power is one of the simple little 9 to 12 h.p. Universal motors. It is capable of driving this boat at a sufficiently rapid rate to comply with all reasonable requirements for speed. This boat is within the range of construction by the amateur builder.

One desiring a smart little runabout suitable for use around the summer home, lake or camp, should find this design interesting. The described motor, though small, will drive the boat at a good clip, and be very economical with the present high cost of gasoline. The divided forward seats and auto steerer provide a convenience not usually found in a runabout of this type, and the cockpit provides ample room for ferrying to and from camp, fishing, or any use a small boat might be put to.--WM. H. HAND, JR.

How to Build a 20-Foot Monoplane (Pub. No. 5435)

The regular hydroplane, although possessing great speed, is nevertheless a very disagreeable proposition to ride in, and it is doubtful whether, below certain lengths, the step is of any importance. In the design of the little boat described herein, use has been made of the bydroplane principles by combining the hollow V-bow with the concave stern section. In this way a boat of maximum speed is obtained with freedom from pounding. Two arrangements are shown: one open, with seating capacity for six or eight persons; the other, a regular auto runabout arrangement.

Building a 25-Foot V-Bottom Cruiser (Pub. No. 5436)

Probably the best thing to do first is to lay the boat down full size—that is, such part as the frames with floors that connect them: the stem, stemson, keel, stern post, shaft log, stern transom and rudder; the figures for doing this are given on the offset sheet and keel plan. If a floor sufficiently large to take the whole boat cannot easily be obtained, different parts of the boat may be laid down separately on a small floor or on, piece of paper. For instance, the stem, frames transom, rudder, etc., can be laid out on separate pieces of paper; so, also, the keel can he laid out on a long, narrow piece of paper.

How to Build a 22-Foot V-Bottom Runabout (Pub. No. 5437)

Generally speaking, the building of a motor boat is a bigger proposition than an amateur should tackle single handed unless he has plenty of time and patience to give it, and unless he happens to be a good mechanic, he is liable to make a poor showing for his pains, for the building of the launch requires skill and knowledge that can not be gained even from the reading of the best articles on” How to Build.” And so it would seem wise to select the least difficult type of boat and make a creditable job and this, too, with less expenditure of labor and material. This not only applies to the amateur builder but also to those building boats for a living, for it is evident that if an equally good, boat can be built for a smaller expenditure of labor and material, it can be sold for less, and other things being equal, price talks. The type of boat described herein is a type too well known to need many comments, as it has been used for years along the coast for the roughest kind of work being an ideal sea boat, but it is only of late that it has come to its own in the motor boat field as a pleasure or racing proposition; and a good part of the credit for this is due to Mr. Hand, who has been experimenting with it for a good many years; and has turned out boats along these lines, that could show their sterns to their round bottom brothers of equal size and horse power without any undue exertion. The general dimensions of the boat are length over all, 22 feet, beam 4 feet 7 inches.

Note: What a great little boat this is and what a fine showing she would make at antique boat rallies. Note the large steering wheel, the searchlight, and best of all--the whistle! With a little tank of compressed air for the whistle, some brass polish on the searchlight and some mahogany, she would be the talk of the marina!

How to Build a 20-Foot Knockabout (Pub. No. 5438)

When working up the design of this little craft the intention was to produce a capable, seaworthy boat, able to stand its share—and more—of bad weather, and at the same time to be an easy and inexpensive boat to build and maintain. A glance at the plans w111 show the flat dory keel, which dqos away with much of the framing and fitting necessary when the conventional keel timber is used and the difficult operation of cutting a rabbet in the keel. Above the keel plank the lines are very similar to the V-bottom model. To simplify the construction the bottom planks are put on vertically, from keel to chine, this doing away with the use of frames and making the planking much easier to fit. This method of planking the bottom also eliminates the necessity of cutting a rabbet in the chine, as is necessary in the true V-bottom type. The motor is installed way aft, as is usual in dories, leaving a large cockpit free from all obstructions. Following the general dory practice the engine compartment iè separated from the cockpit by a bulkhead with a removable section and is decked over. A sliding hatch is provided over the motor of sufficient size to give free access for making the necessary adjustments and repairs.

12-Foot Bangabout, A (Pub. No. 5439)

Just about a year ago at this time, all slicked up and resting quietly in its crate was a nifty little 21/2 h.p. Lockwood-Ash motor which a prize article had previously helped me obtain. Knowing how eager the little putter would be to commence its chug-chug with the advance of spring days, I began to feel as if it was time to get busy and build another little boat if its young hopes were to be realized. While the war was not over at that time, yet I realized that after it did end boating would come back stronger than ever so I laid plans accordingly. As a primary step I began to make sketches and what I had in mind was a neat, stiff little boat, easy and inexpensive to build, capable of carrying a party of three or four people and to be used solely for week-end fishing trips on a good sized open lake. It was a howling cold Saturday night when the final lines were sketched out on paper but with the appearance of those promised nice warm days Jingo was complete in every detail and ready to take on gas and oil. After a successful launching and a summer of continuous use in all kinds of weather on fishing trips lasting from daylight until dark (and well nigh midnight On one or two occasions) I had ample opportunity to test the little outfit thoroughly and it was certainly with reluctance that I gave up to November’s chilling winds and hauled her out. Fur the man who already owns a summer cottage at the beach or the chap lucky enough to possess a camp beside the shore of an inland lake a little boat of the Jingo type is just the craft. Whether it be a clamming trip to a certain distant point way up the beach, a flshing excursion for bass or perch way down in the favorite cove, or a berrying party to the hillside just up the shore, to Jingo it’s all the same, it will take you safely there, then bring you back. Then, too, it is just the kind of craft a couple of kids delight in tinkering about and keeping shipshape.

Minuteman (Pub. No. 5448)

by Charles Bell

LOA 16+', BEAM 8', 42" DEPTH OF HULL

Here is a fast cruising catamaran.

Although she is only 16 feet long, this boat can be made into a comfortable cruiser for two and a good weekend camper for four. Contrary to general belief, catamarans and sea sleds do not afford as much inside room as conventional-type boats. The big tunnel through the middle of the bottom raises the floor and cuts down on the effective headroom that can be safely built into these types. The floor can be lowered on the outside on the larger types and some arrangements which give more room are practical, but on a 16-footer one must make the most of what is available and use the catamaran for its many advantages of hull type. Most of the hurriedly built factory models are simply two long, narrow boat hulls connected by a bridge and any performance advantages are sometimes accidental. Minuteman is the result of long study of catamaran cruiser behavior and her bottom is designed to give the smoothest ride, speed and stability, both on runs and turns, that can be expected of a light water plane. There is a nontrip outer chine and some deadrise to each plane to allow controlled turn without excessive skid or digging in, which could cause a roll over on a tight, high-speed turn. I will say right here that there is no real need for sharp, high-speed turns in any circumstance and this is a stunt practiced by the weak-minded. Minuteman gets the most room out of her 16 feet because in this design I have not allowed the motors to invade the boat but have provided a motor mount as a projection of the hull where the outboards can really be outboard. The transom bulkhead carries the height necessary to a hull of this size and the motor mount provides the dangerously low cut demanded by outboard motors. The motor mount has three large scuppers which drain off water taken into them in a hurry. The bottom of the motor mount is filled with urethane foam poured in place and is covered with plywood to provide a safe place for the gasoline tank or tanks. Any fumes or spillage from them will go overboard through the scuppers, too.

12' 6" Outbard Runabout (Pub. No. 5449)

by Edson I. Schock

This runabout was designed for a general utility, fishing, or family boat. Her carrying capacity is large, and she is steady. Around a camp she is particularly useful, serving as a towboat, grocery truck, marine hayride, or what-have-you. She is not quite as easy to build as the type used for sailing, since the bottom planking has a sharp bend at the bow. This type of bottom, however, is better for a power boat. The bend does not require that the plywood be sprung or steamed, as the bottom is a true developable surface. You should not have any real trouble building her.

16' Utility Runabout (Pub. No. 5450)

by Edson I. Schock

This launch was designed for general all-around usefulness. She may be used for fishing in fairly rough waters, as a small club launch, a family day-boat for rides, picnics, watching races, or whatever other duties you may have to attend to on the water. The little shelter cabin will provide a place to keep things dry and will also be a place to sit in during a shower. A couple of young fellows might even sleep aboard for a weekend cruise. Before attempting to build this boat you should have some skill with tools, and preferably have already built a simple boat, because a boat of this size represents a lot of work, and the complete novice may become discouragd before he is finished. Her construction differs from that of most of the boats in this book as she is not suited for plywood planking, and the narrow plank, or “strip plank” method is specified. This is an easy planking system for amateurs, and it has the further advantage of wasting a minimum of planking lumber. While she was originally designed to carry an outboard motor, she could easily be fitted with engine beds and a skeg so that an inboard engine of about 5 horsepower could be installed.
