In a narrow keeled boat with adjustable walls (10 & 11) and floatation devices 12 & 13) that expand outward to allow for more room in the cockpit and increased stability when needed.
A water vessel has a hull having a maximum width and defines a first portion and a second portion. Each of the first and second portions has an end at which a width of the hull converges relative to the maximum width of the hull. The second portion has a first member defining a first end and a second end. The first end is moveably coupled to the first portion of the hull. The second end is associated with the end of the second portion. The first member is movable between a closed position and an open position relative to the first portion of the hull.
