Title (EN) KEELS
(FR) QUILLES
Abstract:
(EN) A keel comprising two mutually inclined fins (1, 2) which are movable relative to a hull on which the keel is mounted and means such as releasable ratchet devices (31, 32) for locking the fins in any of a plurality of positions relative to the hull. The keel may thus be selectively positioned asymmetrically with respect to the hull to give improved performance and to provide a stable base on inclined surfaces.
(FR) Quille comprenant deux derives (1, 2) inclinees l"une par rapport a l"autre et mobiles par rapport a la coque sur laquelle est montee la quille et des moyens tels que des dispositifs d"encliquetage declenchables (31, 32) pour verrouiller les derives dans l"une des differentes positions par rapport a la coque. On peut ainsi choisir une position asymetrique de la quille par rapport a la coque pour ameliorer les performances et assurer une base stable sur des surfaces inclinees.
