摘要

The catamaran hull module (1) may have an elongated oval shape as seen in plan view. It has symmetrical bow (3) and stern-sections (9) joined to symmetrical midships sections (5,7). The hull module has a non-load- bearing skin made of two hull half-shells joined together along the centerline by a girder acting as a keel. An internal frame supports each hull skin which may be of oval or part-oval cross-section. The frames for the two hulls are connected together.
