ABSTRACT:
A propulsion drive system for boats that is operated by wind power is disclosed. Upon initial observation of a boat equipped with the invention, it looks like a conventional boat. However, after closer inspection, it can be seen that a mast located at the rear of the boat supports a windmill structure. The windmill operates in a horizontal manner, similar to that of an anemometer. The central drive shaft is routed down the mast where it terminates in a gear box which increases the revolutions per minute by a factor of approximately 20 to 1. The output of the gearbox, complete with a clutch, is then routed to a propellor on the rear of the boat which is then used in a conventional manner. The features of the invention provide all of the advantages of a wind-powered boat without any of the disadvantages.
