These plans are for a small bicycle powered craft. The catamaran design gives more stability.
Bouyancy and speed are two features
of this bicycle boat. It consists of
two pontoons and an old bicycle frame,
held centrally above and between the pontoons.
Propulsion is obtained by the use of a ring and pinion gear, bolted to the pedal and sprocket, and a small three blade propeller connected to the gears with the appropriate gearing.
The pontoon is provided with two air vents
made up of pipe fitting's, to prevent the
pontoon from bursting when the air inside
expands in the heat of the sun.
Be sure
to apply glue to the fittings before screwing
them in place over small holes drilled
through the deck, to make them watertight.
The pontoons are finished with a
priming coat of shellac, four coats of good-quality
exterior paint and finally a coat
of spar varnish....
