Abstract: The invention relates to a personal watercraft (100) having a longitudinal axis (X) and comprising: a chassis (102), two rear floats (106) mounted at the rear of the chassis (102) on either side of a symmetry plane of the personal watercraft (100), a foil (116) mounted between the rear floats (106); a movable assembly (150) comprising: a suspension arm (108) that extends in front of the chassis (102), one of the ends of which is mounted so as to be able to rotate on the chassis (102) about a first rotation axis (10), a front float (104) mounted at the other end of said suspension arm (108), and a propulsion means (112) housed in the front float (104), the personal watercraft (100) further comprising a suspension system (114) disposed between the chassis (102) and the movable assembly (150).

Abstract: The invention concerns a floating tidal turbine comprising: means of flotation, a technical room resting on the means of flotation above the water and in which is disposed an electrical generator, a mast immersed in water beneath the control room, a propeller mounted rotationally on the base of the mast around a horizontal axis of rotation, means of transfer that make it possible to transmit the rotational movement of the propeller to the electrical generator, and a manoeuvring system that is designed to raise or lower the mast along a axis that is vertical relative to the technical room.
