PCT No. PCT/GB95/01515 Sec. 371 Date Dec. 20, 1996 Sec. 102(e) Date Dec. 20, 1996 PCT Filed Jun. 28, 1995 PCT Pub. No. WO96/00680 PCT Pub. Date Jan. 11, 1996A twin-hulled boat (1) is constructed from three individual parts being two parallel, relatively narrow and relatively long hulls (2) each individually connected, at releasable joints (13,9), to a central, rigid bridge section (3), and separable, upon release of the joints (13,9) into three individual parts. Each hull (2) has a bow section (4) and a stern section (5). The hulls (2) have virtually flat bottoms (6) apart from the bow sections (4). The releasable joints are two-part metal-to-metal friction joints with one-part (13) of each of said joints located within, and at a lateral side of, said central bridge section (3), and the other part (9) of each of said joints located at inner gunwales (21) of each hull (2), with, for each of said joints, individual independent, screw-incorporating means (26),(24),(27),(29), (33) operable on both parts (13,9) of each joint to urge the parts (13,9) of each said joint together into tight frictional engagement with one another.
