ABSTRACT:
A semi-submerged ship which has twin, parallel submerged lower hulls spaced apart at least two hull widths, a strut structure extending upwardly from the hulls on each side of the ship, and a cross-structure connected between the upper regions of the strut structure to connect the opposite sides of the ship together. The strut structure on each side consists of at least two spaced lower struts extending upwardly from the hull on that side, and a single, full length upper strut attached to the upper ends of the lower struts, the upper struts lying above the design water line at rest.
