A multi-hulled vessel having two submerged streamlined pontoons (10) extending parallel to one another having propulsion units (15, 17) and each having two upstanding structural columns (11) supporting a deck (13) carrying a playload above the water surface. The normal vessel waterline (8) extends through the columns which are of streamlined and preferably are of elliptical cross-section to minimise fore and aft and also transverse drag. |
