Icicle--A speedy 2-seat Ice Boat (Pub. No. 5025)

This smart front-steerer, an up-to-the-minute adaption of the 1937 Class C champion of the Northwestern Yachting Association, will appeal at once to the man who loves to build as well as sail his iceboat. A proven success, it carries 125 square feet of sail, is cat-rigged and has double fore and aft cockpits. The hull is streamlined aerodynamically for real speed. “Icicle” is 24 feet long and the runner plank spread of 16 feet provides a full 14 feet between cutting edges. The after end of the hull or backbone is swept upward to eliminate suction, which retards speed. The original sail area has been reduced slightly to increase iceworthiness in heavy weather but the rig recommended in the drawings makes 50 to 60 miles an hour speed possible in average winds.

Whizz--A fast Class-E Ice Yacht (Pub. No. 5072)

Building this ice yacht, you start by carefully going over the drawings to get acquainted with all constructional details. The six bulkheads, dimensioned in Fig. 5, are cut out of a 5/8 by 24 by 72-in, panel of fir plywood. Centers of all bulkheads except No. 4 are cut out and from the cutout stock of the larger bulkheads, the smaller ones are made. There’s no need to make paper patterns— just lay out the outlines directly on the plywood.

Swordfish--A Racing IceBoat (Pub. No. 5073)

Plans and construction details for racers and non-racers who want to build their own ice craft.

After acquiring the knack of racing with a small iceboat, the average iceboater is ready for a larger and faster craft. With such a craft, he is equipped for an active racing schedule and perhaps for a share of triumph in races. To provide the ambitious racing skipper with a craft equal to his sailing and construction ability, the plans and details, for "Swordfish", a highly capable racing craft, are presented here. At the same time, "Swordfish" is suitable for joy-riding and ordinary sailing by non-racers also. "Swordfish" fills just such a bill, as the original won the Eastern and North American Class B championships. With 250 square feet of sail, "Swordfish" comes under the Class B classification of both the Eastern and Northwestern Ice Yachting Associations, and is qualified to compete in all races of clubs governed by these associations. Thirty feet long, this craft is a front-steerer, which is the spin-proof type. There are two cockpits, with the compartment for the helmsman aft and the sheet-tenders, forward. The breadth of the runnerplank, 20 feet, is ample for weather ability. Safeguards against up-sets are the noncapsizing buffers.

Frostfish (Pub. No. 5175)

by Cal Smith

For top speed thrills on ice build this 161/2 footer.

If you’ve never experienced the sensation of flashing over the ice at 40 mph, you’re really missing a thrill. Building "Frostfish" will put you into this exhilarating winter sport and you can do it for $100— less if you already own a sailing paddleboard, dinghy or canoe. "Frostfish" was designed to be quickly and easily built. Ordinary lumber and construction grade steel are used throughout and hardware store fittings are specified rather than more expensive marine hardware. The sail and spars are adapted from the Alcort Sailfish but lateen or Gunter canoe rigs and dinghy spars and sails of 40 to 65 square feet can be used. Completely portable, "Frostfish" can be taken apart or assembled in a few minutes. The body weighs 65 lbs., the runner plank is 40 lbs. and the rig is 15 lbs.—any of which can be handled by one adult. The total 120-lb. weight is easily carried on top of a car or station wagon. This is a fun craft, easy to sail and highly maneuverable. Carrying one adult or two youngsters, she’ll do 35 to 40 mph in 20 to 25 mph winds. And she’s safe. With the low lateen rig, she stays down on the ice where she belongs.

Iceboat Scoot, The (Pub. No. 5252)

The unique arrangement of the sail and rigging plan of "Scoot" will be apparent as soon as you begin construction of the parts. This special rigging is the secret of the extraordinary sailing qualities that make "Scoot" a top-flight performer

Featuring rudderless steering and a flat, shell-type hull, here’s a unique 15-ft. racing iceboat, the original of which dates back historically to early days when it was used in lifesaving work on New Jersey’s Great South Bay. Born of the necessity of being able to cross the bay even when it was only partly frozen, "Scoot", in addition to its high speed and extraordinary maneuverability, is noted for its ability to take to open water, if necessary, in hurdling large patches of broken ice. Speeds greater than 80 m.p.h., achieved with as many as four passengers, put "Scoot" in the racing class. As a result of its fourpoint runner suspension, its maneuverability is extremely flexible, permitting sharp turns without danger of capsizing or skidding. Steered by manipulating a large-size jib sail, "Scoot" can be held on an arrowstraight course or turned almost literally on a dime. As designed and built by Bill Harless, noted racing champion, this version of the scooter-type iceboat is the result of prolonged experimentation and development. The hook sail rig used is, in effect, a highperformance airfoil and, because of it, Scoot glides along effortlessly in the mildest breezes and really scoots past competition with a strong wind. The boat is moored by merely tipping it on edge with the sails flat on the ice. Except where modified to simplify construction, the plans presented here were taken directly from the actual boat. Original hardware, which was especially designed and cast in brass, has been replaced with less expensive fittings that can readily be improvised from common parts easily obtainable.

Polar Bear--A Ten-Metre Ice Yacht (Pub. No. 5320)

Organized ice yacht racing is increasing rapidly. As with sailing yachts, successful competition in racing depends largely on restricted classes or one design boats. And what a thrill there is in racing at a mile-a-minute! The Polar Bear was developed for class racing at the Maumee Bay Ice Yacht Clubs, Toledo, Ohio, and has proved to be a very popular and successful boat. In general appearance it is somewhat similar to the larger and more expensive 15 metre class, and these speedy little boats will doubtless be widely adopted elsewhere for class racing.

Build Mercury--A Hudson River Iceboat (Pub. No. 5488)

by J. Julius Fanta

If you're looking for a thrilling iceboat design, you’ll like Mercury, the latest creation of the Hudson River type and a fast, trim racer with a moderate rig. This craft is a departure from the usual “banjo” cockpit model in that the crew sits upright and steers as in a car. A comfortable boat in heavy winds, Mercury is 20 feet long and carries 90 square feet of sail. No jib is necessary, as this sail has proved useless on iceboats. There are two cockpits, one located in front of the other. The T-angle iron runner blades prescribed are designed for sailing in snow as well as on clear ice. The laminated backbone construction, which is relatively simple, makes the hull extremely staunch and checkproof. Mercury is steered by remote control, with the steering quadrant coming back into the fore cockpit. Specifications given here provide not only for a weatherable craft but an attractive one.

Build Ice-Sprite--A Four-Runner Ice Boat (Pub. No. 5489)

by J. Julius Fanta

The four-runner iceboat is here for those who demand the most up-to-date innovation in this thrilling sport. The four-runner “Ice-Sprite” design has several features embodying greater safety. With four-cornered support, it rears up and hikes less. Moreover, the hull and sail does not tip forward or backward, as do other types. Because the position of the sail is stationary, capsizing is less likely to occur. In straight going, the rear runners track in the cuts of the fore runners. Thus with two tracks instead of three, friction is reduced and more speed is possible. As it weighs only 210 pounds, it sails and rides easily with added comfort from two runner-planks. The cockpit is large enough to accommodate two or three persons. Ice-Sprite will not spin. Designed with even balance, it requires no anti-capsizing skids on the runnerplank ends. The hull is symmetrical so that it can be steered in front equally well by reversing the direction of the runners and stepping the mast reversed on the after deck. The sail area is only 75 square feet.

Crawfish a 21 ft Streamlined Ice Boat (Pub. No. 5606)

by E. A. Doty

Fast front steering craft with a snug, teardrop cockpit that will protect you from bitter winter winds.

An innovation in front-steering ice-boats is this aerodynamically streamlined cabin craft for those who desire protection from the frigid blasts. Graceful in line and appearance, "Crawfish's" body hardly interferes with fast sailing qualities, because it is ultra-streamlined so that air resistance is minimized to the utmost. Lightly built, its weight is neglible. With an overall length of 28', "Crawfish" has 175 sq. ft. of sail, classifying her as a Class C racer. The cockpit has room for one person beside the pilot.

Portable Ice Boat, A (Pub. No. 5620)

You can carry this ice boat on the roof of your car, and assemble it at the lake. It's fast and safe under sail.

The ice boat described in this article was designed to be transported on top of an automobile using a regular boat-carrier. It also provides a winter use of small dinghy and canoe type sails and rigs. The weight of the boat does not exceed seventy-fve pounds. It steers from the rear, and the cockpit is roomy enough fo the average man or boy. Safe load capacity is 250 pounds.  The material required is low in cost, easy to secure and with the one exception of welding the steering rod to the steering plate the work can be done in the average home workshop.

Quad--A 4-Runner Ice Boat (Pub. No. 5621)

by J.J. Fanta

Those whose interest in building, a four-runner ice boat has kept apace with constant improvements, will find "Quad" just what they had wanted to build and sail.  "Quad" is the near-ultimate of its type, with increased efficiency throughout. Although not as tippy as other types, the four-runner craft hikes safely without throwing the design out of balance. The four-cornered hull prevents the sail’s tilting forward or backward, when heeling; while hiking is lessened by hull precision. Rigid truss-type runner-beams improve the steering functions of this 16’-9”-foot craft. Whereas resilient, springy runner-planks vary the runner adjustment by flexing, rigid runner beams maintain true steering alignment. Riding comfort is provided by mounting the four runners in balanced spring-action units. Steering is by remote control with a wheel in the cockpit operating another forward, which is connected to the rudder-runners with tie-rods. Spreading 75 square feet of sail, this is a single-seated craft for racing in Class E or Skeeter events. "Quad" is light and fast, weighing 290 pounds.

How to build a Motor Ice Boat (Pub. No. 5697)

by Charles H. Guthrie

Terrific speed and the exhilaration of the out-of-doors in winter are fascinating elements of ice boating in its various forms, and particularly is this true of the sport when a strongly built motor ice boat is used. On very smooth, long stretches of ice, the speed is limited only by the power of the mechansim and the endurance of the driver. The possessor of such a mechanical craft will find much more satisfaction in it if he is both owner and builder. The boat described in this article and shownin use and constructional detail in the illustration carries two passengers and the driver.

Ice Boating (Pub. No. 5718)

by Edwin J. Schoettle

The past of ice boating, like much of history, is very obscure. It is generally believed that the Dutch were the first to indulge in the sport and that it came down to them through a long line of ice-loving forefathers. For when one thinks of Holland in winter, does not one always picture the Holland of Hans Brinker—with the ice-covered canals, and the joyous children skating to school or their more dignified elders going to work in like fashion? It is indeed not hard to visualize the same people sailing their crudely made ice boats in ancient times over their well-frozen inland waterways. It is more difficult to imagine the pigtailed chinamen sailing over the ice, but it is almost certain they used ice boats in the days of long ago. In Russia, Norway, and Sweden it is also a favorite winter pastime. The Rudder, February, 1910, published an article on Ice Yachting in Sweden, from which we take this: “Ice Yachting has taken a strong hold in Europe, particularly in Sweden—-the Stockholm Ice Yacht Club, for instance, having a fleet of over thirty-six boats, divided into classes as follows: First Class: For yachts of more than 250 feet of sail—six boats. Second Class: For yachts With 200 to 250 feet of sail—eleven boats. Third Class: For yachts 150 to 200 feet of sail—six boats. Fourth Class: For yachts of 150 feet of sail and under—thirteen boats, four of which used lateen sails.

How to Build a Class E Racing Ice Yacht (Pub. No. 5852)

by T. E. Mead

LOA 18 ft., span 13 ft., MAST HEIGHT 19 ft., SAIL AREA 75 sq. ft., WEIGHT 250 lbs.

The two side planks of this class E ice yacht are of 9/16" x 11y2" x 18' clear airplane spruce. Don't make substitutions on these vital members in order to save a few cents or a few days' delay. The runner plank is also of the highest grade of airplane spruce and, as it is subjected to violent strains, should be of the very finest quality. Select the best two sides of the side planks to be on the outside and then nail them together at the corners with these two good sides together. Mark out the outline of the side planks and frame stations on one side accurately according to the drawings. Use a stiff batten to lay out the curve on the top edges. Be sure that the nails holding the two planks together are in the waste portion and not in the planks themselves. Save the waste portion because you can make some of the deck stringers and miscellaneous small parts out of these pieces. The nose block should be laminated of several pieces rather than cut out of a solid piece because this reduces danger of checking. In all joints of every kind, use "aircraft joint" casein glue. This glue is a white powder and should not be confused with the chocolate colored powder sold in most hardware stores. Its strength and water-resisting properties are far superior to the ordinary household type of casein glue.

Build a South Bay Scooter (Pub. No. 5861)

by Charles R. Meyer

LOA 13 ft to 16 ft., BEAM 4 ft to 6 ft.

Originally designed by the Coast Guard as an amphibian, these rudderless ice boats are now sleek racing machines for winter sailing thrills.

Faster than the wind and trickier handling than any sailing craft afloat, the South Bay scooter was originally an amphibian. Designed and developed by the United States Coast Guard to hurdle patches of broken ice and to supply units of the Lifesaving Service on Fire Island when those personnel were virtually marooned by floating ice, the scooter was refined and eventually evolved into the sleek racing machine found on Long Island today. Featuring rudderless steering and a flat, shell-type hull, today’s scooter is a highly individualistic vehicle. There are no rigid class restrictions to date—scootermen merely differentiate between big and little boats, depending on the canvas carried overhead. SPORTS AFIELD Boatbuilding’s set of plans, drawn by Jesse and Dave Fishman, may be followed exactly, but are usually used as a general template by experienced boatmen and builders. The scooter's performance is determined by the canvas and the sharpness and placement of the lengthwise runners—the hull is more of a platform used to carry passengers and support the structural components. Designed for competition rather than broken-ice navigation, this hull operates well over the ice, but will not give much performance if dunked in a pothole. She will do 40 to 60 mph over the ice under good wind conditions with the proper handling. Your scooter can be from 13’ to 16’ long, with a beam of 4’ to 6’ conventionally.
