Abstract: A watercraft includes at least two floating bodies; a drive device that drives the at least two floating bodies; and a control device that controls at least the drive device, wherein the at least two floating bodies are stacked, the at least two floating bodies are connected by at least one connecting device, at least one damping device is located between the at least two floating bodies, and an intermediate space between the at least two floating bodies is sealed by a sealing device.

Abstract: In a fluid cylinder (1), the piston (2) and the piston rod (3) can be displaced axially by a fluid. Means (5, 7) are located on the fluid cylinder (1) which convert the axial motion of the piston (2) and the piston rod (3) to a rotational motion.

Abstract: The invention relates to a watercraft comprising a hull, at least one motor which is fixed in or onto said hull, and a propeller which is driven by the motor by means of a transmission. According to the invention, at least part of the underwater transmission and the propeller can be laterally pivoted in relation to the watercraft by means of rotary elements.

Abstract: Watch (1), comprising a case (2, 7), at least one watch movement (13, 14) located in the case, and at least one display (3, 4) to display the time of day or other information, wherein at least one section of the watch (7) is movable, specifically, rotatable, wherein the case is composed of an outer case (2) and an inner case (7), and the inner case (7) is movably attached to the outer case, as a result of which a previously nonvisible side of the movable inner case (7) of the watch moves so as to lie on top. The at least one display (3, 4) is located on the inner case, and the inner case (7) is able to fold out of the outer case (2) so that at least one additional laterally oriented display (6) is visible.
