Abstract

L'invention concerne un bateau planant comprenant une coque (1), le fond de la coque (1) étant doté de plusieurs marches espacées dans la direction de la longueur de la coque (1) ; chaque marche comprend une première extrémité proche de la proue (2) et une seconde extrémité proche de la poupe (3) ; pour deux marches adjacentes quelconques, la hauteur de la seconde extrémité de la marche plus proche du côté de la proue (2) est supérieure à celle de la première extrémité de la marche plus proche du côté de la poupe (3). Le bateau planant comprend plusieurs marches espacées au fond de la coque (1), de sorte que lorsque le bateau planant plane, chaque fois que de l'eau s'écoule à travers une marche, elle formera une cavité derrière la marche et formera une surface de planage à proximité de la seconde extrémité de la marche, de sorte que l'eau pourrait entrer en contact avec la prochaine marche après une certaine distance, et ainsi de suite ; les cavités peuvent réduire la résistance au planage du bateau planant dans une certaine mesure, chaque surface de planage présente une petite longueur, c'est-à-dire un rapport portée/corde élevé, et la résistance au planage du bateau planant est par conséquent réduite tandis que la vitesse de planage et la vitesse d'accélération du bateau planant sont augmentées.
