Abstract (en)
The invention relates to surf-board or the like gliding vessels which surf-boards are almost or entirely identical and are shaped in such a way that the stem portion (12, 52) of a surf-board (1, 50) fits into a recess (8, 51) of another surf-board which preferably is identical so that two or more surf-boards can be interconnected to a tandem or multiple surf-board, special locking means being provided to hold stem and stern of subsequent surf-boards strongly together such as cams (20, 21), bushing-pin connections (22, 23 or 36, 37, 40, 25) or tensioning belts (26, 28), or velcro fastener belts between mating surface alone or in combination, whilst in a preferred embodiment the interconnection is obtained by a centre board (53) extending through slots (54, 55, 56) of the mating stern and stem.
