How To Build A Firefly Boat Plans

How To Build A Firefly Boat Plans

FIRE FLY is a high speed, stepped, outboard hydroplane. A new but thoroughly proved method of venting the step for top speed, and a new bottom design, make this sporty craft fast,efficient and seaworthy on smooth or rough water. Fire Fly will exact every bit of speed possible from the power utilized. Outboard motors of 15 to 50 horsepower are best adapted to this super speed runabout. With this hull, the Evinrude Big Four (rated conservatively at 50 horsepower), can plane six persons with ease, haul aquaplanes, and attain speeds approaching 60 miles per hour. However, an outboard motor such as the Johnson Twin (developing around 25 horsepower), will give very satisfactory performance. Fire Fly measures 14 feet long with a beam slightly over 5 feet. The completed weight of this hull is close to 275 pounds. Cost of construction will average about seventyfive dollars. The speed of Fire Fly will range between 15 and 60 miles per hour, depending on which power unit is being used.
