Motion of a floating body is damped by anchoring a piston with a sea anchor to restrict movement of the piston, permitting greater movement of a chamber that surrounds the piston and is fixed to the body, but braking the resulting relative movement between the chamber and the piston by displacement of fluid in the chamber. Thus, a motion damper has a brake structure that comprises a submerged sea anchor suspended in a water column and connected to a piston. The piston is movable within an elongate chamber that is in fixed relation to the floating body and that contains a fluid such as water.
