Abstract

L'invention porte sur un dispositif anti-tangage pour bateau qui comprend un manchon externe (1), une plaque supérieure (2) et une plaque inférieure (3) pour fermer le sommet et le fond du manchon externe (1). Un flotteur (4) est disposé dans la position intermédiaire d'une cavité, à l'intérieur du manchon externe (1). Le flotteur (4) divise la cavité en chambres supérieure et inférieure (11, 12). Un élément élastique supérieur (5) est disposé entre la surface supérieure du flotteur (4) et la plaque supérieure (2), et un élément élastique inférieur (6) est disposé entre le fond du flotteur (4) et la plaque inférieure (2). Le dispositif peut augmenter la stabilité de la coque et sa capacité à résister au vent et aux vagues.
