The ballast for a marine vessel has a central conduit (21) which extends along a part of the length of the vessel. Ballast reservoirs (24) adjacent to the central conduit are positioned so that their lower faces are below the lower edge of the conduit. Pumps pass fluid into and out of the central conduit. A valve is positioned between each reservoir and the central conduit, to control the emptying and filling. The valves are actuated by a remote control.
