Trimaran vehicle deck arrangement

摘要

A multi-hulled vessel (10) configured as a trimaran comprises a main hull (15) and at least one outer hull (17) to each side of the main hull (15) interconnected by a bridge structure (19) and a deck surface (21) adapted to carry a load. Main hull (15) defines at least one engine room (45) and trunking (70) for provision of services to the engine room (45) located below the deck surface (21). Since the trunking (70) is routed below the surface of the area of the deck surface (21) it does not impede load movements. Particularly applicable in ventilation of the engine room (45) through one or more intake air trunks (71) and discharge air trunks (73).
