ABSTRACT:
Apparatus for removing or deflecting surface debris (D) from the moorage site of, e.g., a hydrofoil watercraft (5) having a water-jet propulsion system. Debris (D) is diverted away from the hull inlet (72) of the propulsion system and/or cooling water inlets and/or positions proximate the craft (5) which may interfere with the operation of a forward and an aft strut assembly (15,20) by means of a catamaran pontoon (95). The pontoon (95) is provided with an open-ended debris-conducting channel (100) into which surface debris (D) is guided by a pair of fixed debris guides (105B, 105F). A plurality of elevated stand-offs (115) are supported by the pontoon (95) precluding damage to the craft (5) and the accumulation of surface debris (D) proximate the craft (5). Optionally, retractable debris guides (120B, 120F) may be pivotably attached to the guides (105B, 105F) affording the moorage site greater isolation from surface debris (D).
