Motion of a floating body 10 is damped by anchoring a piston 34 with a sea anchor 38 to restrict movement of the piston, permitting greater movement of a chamber 32 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 24 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. The sea anchor is connected to the piston by means of a link 40.
