Abstract

The vessel is mounted on a skid base (2) which supports a framework. The frame supports the float (3) between end bearings and a deck (1) which carries the pedal and saddle and steering mechanism. The craft may be fitted out for several crew members. The pedals are connected by a chain drive to the float cylinder (3). The float has a helical rib (6) wound round it entire length. This provides the forward motion for the craft. The rudder (5) is connected to the front handlebars. Several floats may be joined in parallel.
