Abstract
A watercraft has a laterally extendable deck or room extension that is extended by sliding along guides or bearings. The deck or room extension can be extended using a motor, gear pinion and rack arrangement, a hand crank arrangement, a hydraulic cylinder arrangement, or a linear motor arrangement. A keel ballast can be utilized to counterbalance the eccentric load caused by the overhanging deck or room extension.
Claims15
A watercraft comprising:
- a body configured to be directly buoyantly supported on water, said body having a perimeter, said body having a longitudinal axis aligned with an intended forward direction of travel of said body through water;
- a laterally extendable first deck portion selectively extendable in linear, sliding fashion from a position substantially within the perimeter of the body to a position extended substantially laterally outwardly of said perimeter of said body;
- a pair of parallel, laterally arranged rails connected to the first deck portion, slidable relative to the body, and, when the first deck portion is in the extended position, said rails extending inwardly of the perimeter of said body from the first deck portion and supporting the first deck portion in a cantilevered manner off the body;
- a second deck portion selectively extendable in linear, sliding fashion from a position substantially within the perimeter of said body to a position extended substantially laterally outwardly of said perimeter of said body, said second deck portion arranged to extend laterally in a direction opposite to said lateral extension of said first deck portion;
- and a pair of parallel, laterally arranged rails connected to the second deck portion, slidable relative to the body, and, when the second deck portion is in the extended position, said rails connected to the second deck portion extending inwardly of the perimeter of said body from the second deck portion and supporting the second deck portion in a cantilevered manner off the body;
- and
- wherein the first and second deck portions are adapted to be simultaneously selectively extendable, so as to counterbalance one another.

A watercraft comprising:
- a hull having a longitudinal centerline aligned with an intended forward direction of travel of the watercraft through water, said hull having hull sidewalls which extend above the waterline to a main deck, and a keel arranged below the waterline, said keel containing a ballast to prevent tipping of said watercraft;
- a passenger-supporting structure, including a horizontal surface, selectively extendable in sliding fashion laterally of the perimeter of the hull, wherein said passenger-supporting structure comprises a room extension which includes a floor, room sidewalls and a roof, said room extension located vertically to extend from said hull sidewalls, between the waterline and said main deck;
- and
- a pair of parallel, laterally arranged rails connected to the horizontal surface of the passenger-supporting structure, and a pair of parallel, laterally arranged rails connected to the roof of said room extension, said pairs of rails extending from the passenger-supporting structure in a direction toward one of the hull sidewalls, and, when the passenger-supporting structure is extended of the perimeter of the hull, said rails connected to the horizontal surface and to the roof supporting the passenger-supporting structure in a cantilevered manner off the hull.

A watercraft comprising:
- a body fashioned for being directly supported on water, said body having a perimeter, said body having a longitudinal axis aligned with an intended forward direction of travel of said body through water;
- a first enclosed room portion horizontally extendable in sliding fashion from a position substantially within the perimeter of the body to a position extended substantially outwardly of said perimeter of said body;
- a pair of parallel, laterally arranged rails connected to the first enclosed room portion, slidable relative to the body, and, when the first enclosed room portion is extended laterally of the perimeter of the body, said rails extending from the first enclosed room portion in a direction inwardly of the perimeter of the body and supporting the first enclosed room portion in a cantilevered manner off the body;
- a second enclosed room portion horizontally extendable in sliding fashion in a direction opposite to the first enclosed room portion from a position substantially within the perimeter of the body to a position extended substantially outwardly of said perimeter of said body;
- a pair of parallel, laterally arranged rails connected to the second enclosed room portion, slidable relative to the body, and, when the second enclosed room portion is extended laterally of the perimeter of the body, said rails extending from the second enclosed room portion in a direction inwardly of the perimeter of the body and supporting the second enclosed room portion in a cantilevered manner off the body;
- and
- wherein the first and second enclosed room portions are adapted to be simultaneously selectively extendable, so as to counterbalance one another.
