Flyer Utility Runabout--A 13-Ft. Outboard, The (Pub. No. 5386)

by Willard Crandall. Design by Bruce N. Crandall

The Flyer Utility Runabout is designed as an all purpose outboard runabout—for family use, fishing—its’ use is unlimited. New features of construction give strength with lightness—thereby creating a boat excellent for all-around use and still a Flyer. It is no longer necessary to have a heavy, slow boat for a utility boat. The Flyer Utility Runabout is strong enough and safe enough for all kinds of use; still it has speed that approaches that of a racing runabout. Bevelled chines the whole length of the boat, with a double bevel toward the transom, make the boat extremely difficult to upset. The bottom is so designed that the boat will not pound excessively in rough water. The V toward the bow will break up the waves when the boat is not planing—the boat performs perfectly with a motor of less than twelve horsepower, the only loss in using the small motors being that of speed. The factors that have given this boat the unusual combination of safety, strength and speed have not made it a boat difficult to construct. There are very few curves to be laid out: only the two last frames on each side and four deck frames. The decking and seating arrangement is very simple. The strong, yet light construction which give the boat the combination of speed, ease of handling and durability is a feature of the design. The boat is light enough so it will plane with a smaller motor than will the average outboard runabout. The main dimensions are: overall length 13 feet 1/2 inch; overall beam 4 feet 2 inches; and beam of the planing surface 3 feet 2 inches.

Toto--An Outboard Motored Runabout (Pub. No. 5387)

Designed by Chester A. Nedwidek

A complete design and building instructions for a substantial little boat of an increasingly popular type which can be easily built

An easily built runabout of a type which is becoming more popular every day, is shown in the present design. Intended particularly for use with any of the larger sizes of outboard engines, it will make an ideal boat for use around a camp, or for general utility service wherever a handy boat is necessary. While Toto is not of the real high speed type of outboard motor boat, such as is generally used for racing alone, it will still be sufficiently lively to suit most people. As can be seen from the drawings, it has been arranged with two separate cockpits or wells, the forward one of which serves as a passenger cockpit, being equipped with seats to accommodate four persons, two on each seat, while the after cockpit is reserved for the use of the operator or helmsman, where he will be alone and undisturbed, so that his entire attention can be centered on the operation of the boat.

Whiz--A 16-Ft. Outboard Speedster (Pub. No. 5388)

A design for an exceptionally fast boat designed to be driven by six to ten horse power outboard engines

For the particular benefit of the speed bug, who must have speed under any consideration, this design for a fast little boat, has been prepared by the engineering department of the Johnson Motor Company. Intended to be propelled by one of the new and exceptionally powerful six horse power, outboard engines, such as that used experimentally last summer by the Johnson Outboard Motor Company, this boat will produce startling results in the way of speed. Similar boats to this were successful in winning many of the competitions, and speeds of 16 m.p.h. were every day events. This little boat follows in general the hydroplane type of design and construction, and in building it, care should be exercised to keep all excess weight down to a minimum point. This boat is sailing under its own colors, as a fast craft particularly adapted to racing. it is not intended to be a family row boat, to take all hands, the children and the dogs out for a day’s outing, as it is too narrow to be a suitable boat for these conditions. When used with one of the big engines, and loaded with not more than two passengers, the results will surprise you.

Baby Buzz--An Outboard Runabout (Pub. No. 5389)

Designed by L. J. Johnson

A design for a fast little boat suitable for family service and purposes other than racing.

Many devotees to the sport of outboard motoring enjoy the speed which is possible with these little boats but still are not anxious to secure the maximum racing speed from their engines. They prefer to have a little more comfort in their boats and for these a design such as the sixteen foot Baby Buzz runabout described below will prove interesting. A boat of this kind is somewhat more substantial than the extreme light racing hulls and is intended to carry several persons in comfort and speed. When built by the amateur builder, care should be exercised to shape all parts carefully and accurately according to the drawings.

Utility--An 18-Ft. Work Boat (Pub. No. 5390)

by Captain W. Mack Angas (CEC) U.S.N.

When several small boats were needed for the Public Works Division of the Charleston Navy Yard, it was considered worth while to try and fine or develop something better than the traditional bateau. We therefore decied to adopt the basic idea of a punt type outboard driven utility boat and design a boat of the size needed. The result was Utility, as handy and useful an eighteen foot work boat as could be desired for the multiudinous odd jobs that fall to the lot of the survey party and waterfront gang at a shipyard. To facilitate beaching, to give working room in the forward end of the cockpit, and to promote stability when heavily loaded forward the boat was given an unusually wide forward transom or stem, but she nevertheless has easy lines and should not be confused with the shapeless boxes that only too often masquerade as punts. Though not built or intended for speed, Utility slips over the water with surprisingly little fuss and has proved considerably faster, when driven by a 5 horse power service motor ahdna 16 foot flat bottom row boat driven by a similar motor.

Sure Mike--A New Idea in Cruisers (Pub. No. 5391)

Designed by E. Weston Farmer, N. A.

The design and specifications for a rough water hydroplane for big outboards which carries a shelter cabin and which can cruise in any water safe for any boat of her inches.

Sure Mike is a he-man’s boat. If it’s bang-and-go-back runabouting you want, something which at low speeds can take the knocks of rough water—a boat that’ll carry quite a load and still be about 10 miles an hour faster than present big outboarders of her size, Sure Mike will not disappoint you. Or if it’s cruising you want—say, let me tell you!—that’s really the thing Sure Mike is designed to do, and do well: to carry a large outboard, utilize its power efficiently and to be able to carry at least two people with abbreviated equipment on a cruise of short duration. There’s a sunken cockpit forward and a big cockpit aft—ample for all rough and tumble runabouting. Her cabin resolves itself into nothing more than sheltered sleeping space, yet it is roomy and comfortable for two. It might have been more, but low freeboard is tantamount to good performance with outboards, largely because of windage although weights too must be kept low for stability when turning. Hence you see no boxcar topsides or other cabin effects in this design. She is fitting and in keeping with the sea. There is no galley. There is no plumbing, nor does there need to be, for her function is to do what a canoe does, only to do it more adequately: carry the duffle and furnish reasonable shelter. She will go anywhere a little boat could possibly go, and she will do that in one sweet heck of a hurry. That’s Sure Mike, and by Joe, that’s enough for any boat!

Dragon-Fly--An Easily Built 181/2-Ft. Cruiser (Pub. No. 5392)

By C. A. Nedwidek

Reliability and power of the new outboard engines adapts them readily to driving larger and abler craft. Complete plans and specifications for a smart little cruiser.

There are presented here the plans and specifications of a small outboard boat, designed so that it is easily adaptable for use as a cruiser. Many outboard cruisers have been designed, but none such as this one. All in all, she is a flat bottom hull with a slight V forward, equipped with seats as shown on the plans, to give a seating capacity for six for day use. The backs of these seats are so arranged that they drop down forming two full length berths on each side of the boat, giving sleeping accommodations for four. A light standing top is shown on the outboard plan; this is to be fitted with side curtains that button along the coaming, closing in the entire hull and giving absolute privacy for the cruising party. Aft on the starboard side the toilet compartment is shown, a light wood partition being built up to a height of thirty inches above the floor line. Directly in this compartment a regular marine toilet fixture is to be installed. The wash basin is fitted on the short leg of the L part of the partition. Putting it in this position will serve the dual purpose of a wash basin and a galley sink, the basin is to be fitted with a small basin puthp that is to be connected to the water tank forward. A curtain or curtains are to be fitted to close in this compartment up to the top of the awning. Opposite the toilet room the galley or cooking portion of this miniature cruiser is to be located and to consist of a built-in ice chest with the top of it acting as a stove platform. The stove itself is optional but the type most practical to use on this boat is one of the folding spirit stoves. They fold up pretty compactly and when not in use, can be stowed under one of the seats. The tanks are to be located forward, one twelve inches in diameter and thirty inches long with a capacity of fourteen gallons, to be used as a fresh water tank, and the other twelve inches in diameter and twenty inches long with a capacity of eight gallons, to be used as the gasoline tank. Both tanks to be filled from deck, with the fill pipes located on deck as shown. The side curtains are to be fitted with windows and screens as shown. The upper rectangles, shown dotted on the outboard plnn, with one of them cross hatched, are intended for screens, while the lower ones are windows, either of celluloid, or just flaps that can be hooked up. Windows are also to be fitted in the forward and after curtains, three windows in each.

Doodlebug--A 12-Ft. Inboard Monoplane (Pub. No. 5402)

by John L. Hacker

The current interest in motor boat racing, more particularly in boats of small size, has led to the design of a brand new little boat. Abler and more sturdy than like outboard types, it will provide great sport and competition among the growing generation of youngsters. The idea for this little Doodlebug was conceived during the recent Motor Boat Show in New York. John Hacker, the designer, was much taken with the possibilities of marine plywood as a boat building material. The tests and demonstrations of its use were very impressive. Later during the show he found a small motor which was being introduced by the Arnolt Motor Company under the name Sea-Mite. The combination of a little boat built of plywood and powered with one of these engines was immediately apparent. Mr. Hacker accordingly set about the preparation of a design and the construction of a boat. This first boat was later exhibited at the Chicago Show, where it met with universal approval and favor.

Slippery--A 135-Class Hydroplane (Pub. No. 5403)

by John L. Hacker

The racing of small hydroplanes is becoming one of the major sports of the boating world. Many excellent and skillful drivers who have acquired their experience in the hard way of the outboard, are turning to the inboard as a means of satisfying their craving for speed and excitement. Small inboard hydroplanes, while not so extremely fast, are still capable of relatively high speeds and offer equally good competition, particularly in the standard racing classes such as the 91, 135, and 225 cubic inch types. The little design presented herewith is intended for the 135 cubic inch class. Other designs published previously take care of the smaller and larger classes as well, so that this design rounds out the series. The design of Slippery is based on numerous successful small hydroplanes in these several classes. While the design is conservative the boat will give a good account of itself in competition, and at the same time serve as a smart sporty runabout when desired for such use. It is a small boat, 14 feet 31/2 inches in length, with a maximum beam of 4 feet 91/2 inches. There are several racing engines suitable to the class now on the market so that no difficulty will be experienced in securing a satisfactory engine.

Jane, A Hand 18-footer (Pub. No. 5409)

by Wm. H. Hand, Jr.

Our plans this month are for a fast little runabout of 18 feet in length. When equipped with the Specified 20 h. p. Kermath motor this outfit should be able to do 17 to i8 m.p.h. without any difficulty at all. The design of this little boat is in a general way similar to the one published last month. When it comes to power plant, however, we see that the design is entirely different. The engine is more nearly amidship and the cockpit aft is entirely clear. This location of the power plant shifts the weights further forward and compensates for the weight of passengers in the cockpit. When under way the tendency to lift out forward or plane is counteracted to the proper degree by the selected motor. That explains to some measure why the naval architect is so particular in the selection of the power plant. Having designed a boat and figured on its speed and angle of planing and a lot of other things, he does not like to see his calculations entirely upset by some smart novice who decides to put in a bigger engine and get more speed. The inevitable result of this is to bring the boat down by the head, interfere with the lifting out forward at speed, and the creation of a tremendous fuss at the stern, while, strange as it may seem, the speed does not improve at all. The valuable lesson to be learned from this is that the naval architect has very good and sufficient reasons for everything that he dopes in the design of a boat. The weights are calculated, and the engine is located at a particular point. The seats are located with a reason, and any attempts to improve on the design on the part of the novice are certain to result in failure as far as satisfactory performance of the boat is concerned. Mr. Hand has had ample experience and skill in turning out fleets of small boats, and his designs should be followed without changes.

Flyer--A 91-Cubic Inch Racer (Pub. No. 5410)

by Willard Crandall. Designed by Bruce N. Crandall

A new design inboard hydroplane

Ninety-one and a half cubic inches—the smallest of the inboard hydroplane racing classes. The very size of the class guarantees its eventual popularity. Smaller racing classes have steadily gained in favor as improvements in engine and hull design have consistently raised the speeds in each class. The 91 cubic inch class, for which this new Flyer was designed, has several unique rules which will, aid in popularizing racing in it to a marked extent. A price limit is placed on the motor; $450, retail, is the highest price that can be affixed. Superchargers are barred. The waterline length of the hull must not be less than twelve feet; the chine beam at the widest section must be at least four feet. A total minimum weight for the hull and motor is prescribed—600 pounds. While it has been borne in mind that many persons will wish to build the 91 cubic inch Flyer not exclusively for racing, no element of speed or handling qualities has in any way been sacrificed. Yet features of this craft will make it an excellent speedy runabout for use in more sheltered waters. Such features consist partly in the double seat and provision for use of starter, following racing rule requirements. The design as shown also provides for reverse gear and hatches over the motor. These are not called for by the racing rules but the builder who wishes to leave them off should be careful that in doing so he does not lower the total weight of the outfit below 600 pounds. Total weight will, of course, vary with the motor used.

Speedo--A Novel Outboard Boat (Pub. No. 5413)

Designed by Harold Tapken, N.A.

A sixteen foot outboard engined runabout with the engine mounted amidships.

What do you think, of putting the motor in the thiddle of the boat and the driver further back toward the stern, so that the boat might trim on an even keel when at rest? The engine, of course an outboard motor of the usual form, must be placed in a well, so that it can be removed at need, if anything happens to the propeller or a shear pin breaks. Now this well would have to be rather large, say 11/2 feet in length and about one foot wide. The water would rush into it, as soon as the boat started, and the faster the boat went, the more the water would shoot into the well, causing great resistance. So one would have to fit a lid to the bottom of the well in order to make it watertight and prevent the water from rushing in. This now presents some great difficulties, for the underwater parts of an outboard motor are rather awkwardly shaped and the lid would have to fit perfectly tight, while on the other hand it should be easily removable. The more we thought about the details, the more complicated everything seemed to get, so that we soon began to look about for another way of fitting the motor, or at least another form of well, if one could not do without this. Well, what about fitting a step? Even if the motor were not very powerful, its power would just be sufficient to push the boat along at planing speed, so that a step would not add to the resistance in any way. As the water tears off at the step a good part of the boat's bottom is clear of water as soon as a certains peed is attained. If, now, the well is placed at this point, no water could possible run into it, as soon as the boat is under way. The top half of the motor was turned around so that the carbureter pointed backwards towards the driver, who only had to stretch out his hand to make any necessary adjustment. It was a great idea to lead the exhaust gases through a flexible pipe into the step, where they could expand readily, as there would not only be no back pressure to overcome, but where they would be drawn away by the vacuum, which occurs just behind the step. In order to give the exhaust a free passage, the muffler was removed, with the hope that enough silence would be obtained by the gases expanding under the bottom of the boat, metal fins being fitted to prevent the sound from taking the shortest way out. In this way we hoped to get rid of the back pressure, as well as the noise, and the arrangement proved to be a success in every way. Instead of the clumsy motor hanging at the transom, it was neatly tucked away and visible only from behind. The boat therefore had the appearance of a real motor boat with inboard engine, but had the advantage, that the motor took up hardly any space inside the hull, the entire bow portion of the boat being left for useful purposes, even being spacious enough to permit an afternoon’s nap.     A second virtue of the boat is that it always trims well, at rest, at slow speed, and high. This fact makes the boat easy to handle and very seaworthy.

Hoocares--A Tabloid Houseboat (Pub. No. 5414)

by E. Weston Farmer, N. A.

Plans and specifications for a miniature floating home which is driven by an outboard motor and which can cruise safely where the water is spread thin.

Some people seem to think that a small boat on the tabloid order, to be worth anything, must be the kind of hooker into which one can throw a dozen muffins at a moment’s notice, and with a beautiful slant of wind sail down to Cape Horn for afternoon tea. Along with numerous others, this humble writer has long differed with that contention. I am a firm believer in boats for a purpose. I believe that the most satisfactory boat to own is the kind of boat which actually fits the water in which she is nominally at home when roosting time comes and the hook slops overside into its usual resting place. Sailing tabloids have their mighty interesting points. In fact I am working right now on a salty little deep water lady and would be the last soul on earth to condemn them. But too much emphasis cannot be laid on the fact that a tabloid design, appealing to a man’s sense of economy coupled with the itch to own a boat, may often lead him to building a boat he has no particular need for, as after all, the great majority of boating done in these anxious days confines itself to day boating an hour or two from moorings. Ergo, we have Hoocares, patterned for sheltered waters and ditch crawling after the manner of the Holland hoogarts. She was designed for the man who knows that the bulk of his adventures will confine themselves to sleeping aboard a bit, to readings and mug-ups of a chilly Saturday afternoon, and to making use of her comfortable mobility in avoiding monotony of anchorages. Her name Americana of course, for hoogarts, which is Dutch for, well, it’s in the dictionary—and because of the adaptability of the general idea of the hoogarts to the uses this needed tabloid might be put to, I have swiped the general idea and made our little hooker something of a Dutchman—beamy, housed across her midriff, blunt of snoot and thin on the underfoot side. Lets have a look at her from the cruising standpoint. About the first novelty you’ll notice is the fact that you don’t have to grease your hide to get in and out of her accommodations. They’re actual instead of alleged. And paradoxical as it may seem, there’s absolutely full headroom, I don’t care how tall you are. The only place there is room enough for two man-sized feet is right under her ample hatch, although there is good footroom all along the face of the bunk, from the pail which acts as a sink, to starboard, past the Shipmate near the companionway over to the hinged lid which nonchalantly burns a Murad over what’s under. Hoocares in her culinary and sewage departments is as neatly arranged as I believe is conceivable.

Flyer--A 135 Cu. In. Class Hydroplane (Pub. No. 5415)

by Willard Crandall

Designed by Bruce N. Crandall

Absolute maximum speed, is the cry of many race drivers. For a race, they want a boat that will go fast--sufficiently fast to win; and if it will, other features of it do not matter. The 135-Class Flyer is designed to give maximum speed, but maximum speed under normal competitive conditions. Factors of design giving straight-away speed, turning ability, and ability to ride rough water have been so proportioned that in an actual race a high peak of speed is reached. As can be seen from the profile drawing, a perfect stream-ling has been achieved. The 135-Class Flyer has been designed on the principle of carrying most of the weight on the foreplane, so that a wide afterplane is not necessary. While length and beam are somewhat over the minimum prescribed, because of its shape it is, really, a small boat. Construction is much more simple than it might appear offhand. The pointed stern is built similar to an upside down bow. The transom is used the same as ever, and serves as an additional bulkhead. No rabbeting, except in the stem, is required. The type of construction called for is about as light as is practical considering the strength necessary and it is not advisable to build the boat lighter.

Zephyr--A 135-Cubic Inch Hydroplane 16-Ft. Overall (Pub. No. 5416)

by A.A. Apel

Motor boat racing is always popular and these plans are made with the man in mind who is enthused with racing and prefers to build his own boat. Although the building of a high-speed racing hull is of a particular nature and fairly complicated, it is the endeavor of the designer to simplify the instructions and plans as much as possible. As will be noted in the design, the boat has an over-all length of 16 feet with a beam of just about 5 feet. To make it easier for the amateur to build, the construction has been simplified without sacrificing strength where it is necessary.

Katherine, A Hand 30-foot Cruiser (Pub. No. 5417)

Designed by Wm. H. Hand, Jr.

Continuing the presentation of plans of famous Hand V-bottom boats, we publish this month a complete set of plans and specifications for a 30-foot cruiser, Katherine, which is as complete and able a boat as it is possible to find on the seven seas. The enthusiasm which greeted the appearance of the two Hand V-bottom runabouts will be redoubled with the publication of the plans of this 30-foot cruiser. This boat is a sizable, well-constructed and thoroughly able little sea boat. Fast enough to get anywhere and back again before the trip becomes monotonous, and comfortable enough to enable a small, congenial party to undertake a lengthy cruise far from the beaten paths, its cruising range being ample for several days’ cruising before the item of fuel becomes troublesome. The construction of this boat is of course more difficult than the runabouts published before. Undoubtedly a professional builder would make the most satisfactory job of this boat. Whether it is advisable for the unskilled amateur to undertake its construction is a serious question. While 30 feet is only twice 15 feet, the amount of work involved is nearer ten times as great. There is decking and flooring and ceiling and plumbing and finishing and many other items to be done and the amateur to tackle a job of this kind should be quite certain that he is possessed of the requisite skill and ability to see it thçough. As our arrangement plan shows, this boat is provided with a lavatory in the bow, next are some very, useful full length lockers to hang clothes and oilskins. Everyone will admit that lockers of this type are just the kind they have been wishing for. A ventilating hatch in the deck above the cabin is a further useful addition for comfort. Two transom berths in the cabin provide comfortable sleeping accommodations for two people, and if necessary swinging backs could he installed to provide berths for two more. The galley is large and commodious, the platform for the stove is over the refrigerator and all heated air can readily flow out through the companionway hatch. The cabin can be kept cool and comfortahle and odors due to cooking are readily disposed of. The port side provides place for the sink, and pantry with dish racks, etc., close by. In the large cockpit ample space is provided for easy wicker chairs which can be left behind if the party is to be a small one.

How to Build Consort II (Pub. No. 5418)

The accompanying illustrations are those of a small cruiser that was designed primarily with the idea of being easily constructed, in order that the average amateur who has some practical knowledge of the use of carpenter’s tools could build a boat. No doubt many will criticise same; the stern should be different, the stem should have more rake, etc., but the èxpIanation given above should be a sufficient excuse for the general shape of the boat not meeting the requirements of all. If the instructions for building this boat are followed carefully, the builder will be surprised to find out how much he has learned about building by the time he has completed this craft. Then later on the knowledge he has gained will be of material assistance when he again considers the building of a larger boat. Some of you will smile at this and no doubt think that a boat of this size would be as large as you would ever need, but I have been there, and know how natural it is for one to realize quite often that the boat which he thought so large and commodius is just a trifle too small.

Gull--A 16-Foot Runabout (Pub. No. 5420)

by Chester A. Nedwidek

An attractive design for a small vee bottom runabout or yacht tender which has been simplified to permit of construction by amateur builders.

The design for Gull which is presented here, is that of a small Vee bottom runabout, which will serve equally well as a yacht tender for a boat which requires a tender as large as this. The shape of the hull has been kept as simple as possible, in order to make it easier for the amateur builder to undertake and complete.

Skeeter--A Fishing Skiff (Pub. No. 5421)

by C. A. Nedwidek

Design, specifications and building, instructions for a most useful shallow draft tunnel stern utility boat of an economical type.

This little boat was designed for the use of those who like to prowl up little creeks and bays where the water is spread out, those places where a deep draft boat cannot get by. She also will be useful for duck shooting to tow the duck boats and equipment to the shooting blind. Many localities are blessed with an abundance of water but it is spread out so thin that the ordinary type of motor boat is useless. For these conditions the only satisfactory type of craft is a shallow draft and tunnel stern job. The little boat designed here will suit such conditions exactly and will operate in from 9 to 10 inches of water. An economical little engine and a simple form of construction will make the entire job very inexpensive. For many places and conditions this will be an ideal craft and will answer fully every requirement for a useful little pleasure craft.Being of a very simple design no difficulty should be encountered in the building of her. She is absolutely flat bottom with slightly flaring sides. The tunnel construction is of the usual box type, easy to build; in the design of this tunnel the sides have been carried down to form a skeg, this will give a sled effect in that two of these skegs will drag over the bottom should a real shoal spot be encountered, and still give protection to the wheel and rudder. As designed, these extend down nine and one-half inches below the water line giving the boat this draft. The interior arrangement is just that of an open boat, with a short deck forward, two athwartship seats, engine with a box over it and a short after deck, outboard rudder with the tiller carried through the transom and connected to a side steering wheel with the tiller lines.
