A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.

According to embodiments of the present invention, an underwater hull cleaning machine is provided. The cleaning machine includes a housing including a base region adapted to be arranged facing at least part of an external surface to be cleaned; a guiding mechanism coupled to the housing, wherein the guiding mechanism is configured to enable the cleaning machine to be maneuvered along the external surface; and at least one brush configured to move between an extended position and a retracted position. In the extended position, the at least one brush is extended downwardly towards the base region to be in contact with the external surface. In the retracted position, the at least one brush is moved upwardly away from the base region to be free from contact with the external surface. According to further embodiments, a hull cleaning system and a method for cleaning a vessel hull are also provided.
