ABSTRACT:
In an aquatic vehicle with one or more hulls, a chamber (10) is formed in the boat or hull (19, 7). The chamber has at least one opening (13) which can be closed via a closing element (14) and at least one vent (20). The closing element (14) opens the opening (13) by itself when the boat or hull (19, 7) is immersed in the water and closes it by itself when the boat or hull (19, 7) is raised out of the water.
