Abstract
A marine vessel is provided which comprises a platform member, two parallel hulls disposed below the platform and adapted to be below the water surface when the ship is in operation, each of the hulls consists of an after section, a forward section having a smaller cross-sectional area than the after section and a central section having a cross-sectional area substantially smaller than that of the forward section and supported only by the junctions with the forward and after sections. Both forward sections and both after sections are joined to the platform member by strut-like members which are tapered so that their waterplane areas increase rapidly between the waterline and their junctions with the platform member.
Claims5
A marine vessel comprising:
- (a) a platform member;
- (b) two parallel hulls disposed below said platform and adapted to be below the water surface when the vessel is in operation;
- (c) each of said hulls comprising a pod shaped after section, a forward section having a generally rectangular cross section of substantially smaller cross-sectional area than the after section and a tubular central section, having a cross-sectional area substantially smaller than that of the forward section, joining the forward end of the after section to the after end of the forward section and supported only by the junctions with the forward and after sections;
- (d) each after section being joined to said platform by a strut-like member;
- (e) each forward section being joined to said platform by a strut-like member;
- (f) all of said strut-like members being tapered so that their waterplane areas increase rapidly between the waterline and the junction of the strut-like member with the platform;
- (g) the junctions of the strut-like members with the hull sections being so constructed that a portion of each connected hull section extends forward of the junction.
