A boat driven by paddlewheels equipped with v-shaped voluminous blades

摘要

A boat where propulsion is provided by the use of paddlewheels 3 equipped with v-shaped voluminous blades and where the said paddlewheels are positioned to utilize water displaced by the hull 1 in order to increase the effectiveness of the paddlewheel. Power to turn the paddlewheels may be provided by means of a pedal drive arrangement 5, 6, 7 and 8 or by means of a motor. The output of water from the paddlewheels 17 is able to fill in areas 16 at the rear of the hull to minimise suction on the hull.
