Abstract: A multi-hulled vessel (10) configured as a trimaran. The multi-hulled vessel (10) comprises a main hull (15) and at least one outer hull (17) to each side of the main hull, the main hull (15) and each side hull (17) adjacent thereto being interconnected by a bridge structure (19). The bridge structure (19) and the hulls (15, 17) connected thereby cooperating to provide a deck surface (21) adapted to carry a load. The main hull 15) is configured to define at least one engine room (45) below the deck surface (21) and trunking (70) for provision of services to the engine room. The trunking (70) is routed below the area of the deck surface (21) required for carrying a load. Because the trunking (70) is routed below the area of the deck surface (21) required for load-carrying, it does not extend through that area of the deck surface to impede load movements.

Abstract: An amah for a high speed seagoing multi hulled vessel, the amah having sides extending upwardly and outwardly from a base line, the sides having longitudinally extending vertically spaced stiffeners, the bow of the amah including a plate field comprising a plurality of sub plates each comprising a vertical plate secured along the centre line of the amah and supporting a horizontal plate secured to each side of the amah, whereby the planes of the horizontal plates of the sub plates step upwardly as the base line rakes upwardly towards the bow and the longitudinal stiffeners terminate and are secured to the horizontal plates.
