CA 2283681

The invention concerns a device (50) for altering the course of a boat equipped with an automatic control system with magnetic compass (5), actuated on receiving an alarm signal (ba) and comprising means for blocking the compass on a fictitious North. The invention is characterised in that the means for blocking the compass comprise two coils (B1, B2) arranged in the proximity of the compass along complementary axes, means (21, 22, 23, 24) for exciting each of the coils in accordance with a course signal (r1, r2, r3) or a signal of the boat list (bi), so as to preferably make the compass (5) turn counter-clockwise when the list is on starboard side and clockwise when the list is on portside, whatever the route followed by the boat.

La présente invention concerne un dispositif pour modifier la trajectoire d'un bateau équipé d'un pilote automatique à compas magnétique, se déclenchant sur déception d'un signal d'alarme et comprenant des moyens pour bloquer le compas sur un Nord fictif, et un système anticollision pour un tel bateau, comprenant au moins deux bobines disposées à proximité du compas selon des axes complémentaires, des moyens pour exciter chacune des bobines, des moyens pour répartir l'excitation des bobines en fonction d'un signal de route et d'un signal de gîte du bateau, de manière à faire tourner préférentiellement le compas dans le sens trigonométrique quand le gîte est à tribord et dans le sens des aiguilles d'une montre quand le gîte est à bâbord, quelle que soit la route suivie par le bateau.
