The idea was taken from the principle of semi-submersible offshore rigs, designed to provide a working platform with minimised motion in open sea.

Splet01. jan. 1989 · Meyerhoff LOADS The structural design of a SWATH hull deviates from that of a conventional hull in that the primary loads are the side loads acting on the lower hulls and the struts. SWATH side loads may well be compared with the longitudinal bending of conventional hulls. SpletThe designers shrunk the waterplane area until it was a small strut, just wide enough to fit a crew member down. All the buoyancy got concentrated into deep submerged hulls, which looked more like a submarine hull. And the SWATH was born: a vessel with excellent seakeeping because waves exert very little force on it. (Figure 1‑2) The force of ...
