ABSTRACT:
A sailboat having a tetrahedral frame formed of six beams, three of which form the triangular deck with three hulls disposed at the vertices of the triangular deck extending outward from the plane of the deck. Two masts are formed by two of the three beams extending upward from the deck. The third beam completes the tetrahedral space frame structure and makes the assemblage rigid, and allows for easy folding of the sailboat space frame structure.
