Abstract
A catamaran having two parallel symmetrical hulls of equal size spaced apart with a superstructure lower deck extending from an outer edge of the first hull to an outer edge of the second hull. The lower deck is positioned above the static waterline and provides a single, constant, flush elevation height across the entire length and breadth of the vessel, with the placement of control and propulsion machinery in the hulls. The improved catamaran has an increased freeboard, increased gross tonnage, and decreased design pressures on the superstructure scantlings of the catamaran deck as compared to a conventional catamaran having a lower deck mounted beneath the static waterline, or accommodations added to the hulls.
Claims7
A full beam accommodation space for a catamaran vessel comprising two parallel symmetrical hulls of equal size that are spaced apart forming a port side hull and a starboard side hull, each said hull having a bow and a stern with a longitudinal bottom forming a length, each said hull having an inner sidewall and an outer sidewall extending above a static waterline defining a technical space in each hull for placement of propulsion machinery;
- a superstructure lower deck secured to said port side hull and said starboard side hull at a predetermined position above said static waterline, said superstructure lower deck having an upper surface constructed and arranged to provide a single, constant, flush elevation across the entire length and breadth of said catamaran vessel creating a full beam accommodation space;
- at least one sidewall secured to a side edge of said superstructure lower deck, said sidewall rotatable from a vertical storage position to a horizontal position extending said full beam accommodation space;
- whereby said technical space within each said hull contains propulsion machinery and said full beam accommodation space formed on said upper surface of said superstructure lower deck extends from said port side hull to said starboard side hull and extendable outwardly therefrom by rotating said at least one sidewall, wherein said superstructure lower deck width is extended.
The catamaran vessel according to claim wherein said superstructure lower deck placement is constructed and arranged to provide increased freeboard and gross tonnage over a conventional catamaran having accommodations placed in a portion of each hull.
