Abstract
(EN)
Pastime-, model- or racing-catamaran with induced hydrodynamic stability, comprising a hull formed of a board (1) and a pair of semi-submerged appendices (2, 3; 8-9; 13-14; 24, 25) having an elongated longitudinal extension and placed along parallel sides of the board (1), the respective bottoms of which at both their forward ends (4, 5; 12, 12a; 21, 22; 32, 33) show mutually opposite slopes, directed contrary to the slope of aft bottom rest.
(FR)
Le catamaran décrit comprend une coque formée d'une planche (1) et d'une paire d'appendices à moitié immergés (2, 3; 8-9, 13-14; 24, 25) munis d'un prolongement longitudinal allongé et situés sur des côtés parallèles de la planche (1). Leurs surfaces inférieures présentent, à leurs extrémités avant (4, 5; 12, 12a; 21, 22; 32, 33), des parties inclinées mutuellement opposées, disposées contrairement à l'inclinaison du support de fond arrière.
