    • 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.

    • For securing a heavy wire rope (hawser), usually to the bow or stern of a large vessel but alternatively to an oil rig or jetty, a bollard comprises

      (a) a base (B) securable to a deck and having an upstanding cylinder (10) around which is an angled skirt (12) or a plurality of angled brackets (15);
      (b) an upper portion having a cylinder (24) which fits rotatably within the base, and on top of which is a round plate (22) on which is fixed a fin (20), usually a pear-shaped base and the upper portion of which extends at an acute angle to the horizontal and terminates in a narrow peak under which is a notch (23) for retaining the rope, and
      (c) for retaining the two portions in a desired non-rotating position, corresponding lateral holes (30,32) in the respective cylinders (10,24) and at least one locking bar which can be inserted through both cylinders.

      The upper portion can be rotated manually by inserting a bar in a hole (26) beneath the peak of the fin; or by means of a small motor.
      The two sections may have respective screw threads (16,18).
      The bollard allows a heavy rope to be secured or released by one man.
