Abstract

La présente invention concerne un dispositif destiné à être utilisé à bord de navires/bateaux pour prévenir les éventuels échouages. La présente invention concerne un nouveau procédé et un dispositif qui fait automatiquement la différence entre un cap sûr et un cap qui peut aboutir à un échouage. Le dispositif n'émet pas d'alarme même si le navire est très proche de la terre si il suit une trajectoire habituelle jusqu'au port.
