1. A truss-supported ski-borne watercraft, comprising:
a. at least one body having a deck and surface;
b. a first horizontal longitudinal ski set below the at least one body and at least a first vertical truss support member, said first horizontal longitudinal ski supporting a watercraft via a truss comprising:
i. said first vertical truss support member, and
ii. a first diagonal support member;
c. a platform set above a top surface of said first horizontal longitudinal ski, said platform supporting at least a first motor in a motor box;
d. a second horizontal longitudinal ski below said at least one body, said second horizontal longitudinal ski supporting the at least one body via at least a second vertical truss support member, and a second diagonal support member, said second horizontal longitudinal ski positioned starboard, relative to first horizontal longitudinal ski, and further coupled to said first horizontal longitudinal ski via a truss connecting member, wherein said at least one body is at least partially supported by said truss connecting member;
e. wherein said first and second horizontal longitudinal skis comprise a height, a thickness and a width, creating a volume, wherein a combined displacement of water from said volume is sufficient to support the at least one body above water when the watercraft is loaded at rest; and
f. a propulsion means for propelling the watercraft, said propulsion means powerful enough to provide lift to raise said first and second horizontal longitudinal skis above a water surface, each of said first and second horizontal longitudinal skis comprising a lower planing surface adapted to mate with the water surface and to support said watercraft and provide for planing against the water surface and wherein when planing, a propeller mechanically coupled to said motor box remains below said lower planing surface.
