DELVIS NEDDYKKET KATAMARAN.

摘要

A semi-submersible catamaran comprises two lower hulls (11), always located below the waterline, which are parallel to one another and lie in the normal travel direction. Vertical plate-like struts (12) are mounted on the lower hulls (11) and an upper hull (13) is supported on the struts (12). The upper hull is always above the waterline. The invention provides particular ratios between the submergence depth (f) and the average diameter of the lower hulls (11) and between the height HL and width BL of the lower hulls (11). The invention also provides a particular fin arrangement (16, 16') provided on the lower hulls (11). The catamaran may be used, for example, as a passenger ship, a cargo boat or a floating factory ship.
