ABSTRACT:
A wind-propelled craft having at least two elongated, low-profiled, flat-bottomed floats. The floats are parallelly and distally connected by a framework adapted to support the wind propulsion structure. The framework and floats are connected by fore and aft articulated joints which allow for arcuate travel of the framework and propulsion means relative to trim while maintaining level positioning of the flat-bottomed floats in relation to the medium being traversed. The floats, therefore, do not heel into the water. Resistance to the craft's speed and manueverability is thus diminished because the craft planes upon the water rather than heeling into it as is the case with conventional hulls and float assemblies.
