摘要
The invention pertains to a vessel for operating on water comprising, a round-bilge hull (1) hull having a design waterline (9), a length at the design waterline LwI, a maximum beam at said design waterline Bwi situated aft of the mid- length of that waterline, and a centre-line buttock (7) which forms the deepest part of the hull from the bow to a position short of the mid- length of the design waterline, and then runs aft in a smooth curve, at a shallow angle relative to the horizontal, a bulb (15) at the bow to further reduce hydrodynamic resistance and to widen the hull at the bow below the design waterline without increasing the entry angle of the relative waterlines there, with a length and width, and with the widest part located relatively close to the design water line, a spray rail (18) on, or integrated into, the fore-body of the hull and a trim device (21) fitted at or near the transom stern for controlling the running trim of the vessel.
