A ship, e.g. a bulk cargo carrier, which uses power from the waves of the sea or other water on which it travels, comprises a hull (14) containing at least one cargo container or hold (10) each mounted so as to rock slightly upon supporting pistons fitted between girders (18) within a compartment of the hull. The hydraulic pistons are placed at the side (16) and beneath (22) each hold and are actuated by pressure of the hold as the hold moves; the pistons are linked by hydraulic pipelines (24, 25) to an engine room where gear wheel pumps are driven which drive a propeller and optionally electric power is generated. Each hold preferably is circular, tapering slightly so as to be narrower at the top, with a slightly conical base so as to rock from side to side and fore-and-aft; beneath each hold is one or more circles of pistons. An auxiliary engine can be fitted for use in calms and harbours; but otherwise no fuel is needed to propel the ship. |
