ABSTRACT:
A wind powered vehicle including an operator platform having tilting and stationary sections coupled together via a plurality of hanger bearings and a longitudinal pivot axle. The platform section tilts with foot pressure applied at a stirrup to direct a forward steering assembly. The stationary platform section includes a resilient suspension and supports an opposite foot of the operator. The forward steering assembly provides a tilting, center biased steering turntable and axle. Adjustable axle bearing collar support and shock absorbers support forward and aft pairs of skis, wheels or runners which are tilted at opposite caster angles. The steering assembly, hanger bearings, cable truss supports and a sail coupler are each longitudinally adjustable along the length of the platform. In alternative configurations, wheels are mounted to the fore and aft axles; the platform includes spray guards; or the vehicle is constructed with water skis and the platform is constructed to provide flotation.
