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.

A wind-propelled craft comprising: at least two elongated, semi-flexible low-profiled and flatbottomed floats; a framework adapted to support wind propulsion means and at least one user, said floats being distally and parallelly connected by said framework; on each float, at least two articulated joints each having fore-and-aft rotational axes rotational independently of the joints of the other float, and transverse axes, said joints connecting said framework to the central fore-and-aft line of each of said floats such that said hulls are free to rotate about their fore-and-aft axes in response to changing heel angles of said craft, and free to adjust about the transverse axes in response to pitch flexure of said hulls; and said floats containing openings medially positioned and lined with resilient bushings to house anti-slippage means which move with said framework when same heels such that said anti-slippage means enter the water at the angle of heel of said frame rather than straight, and said resilient bushing permits the non-orthonormal passage of said anti-slippage means through said openings while securing same against loose motion in said openings.
