A kayak characterized by a kayak hull molded of semi-rigid material stiffened by an internal frame structure which includes a bow and a stern beam units and a seat each of hollow and watertight construction to provide buoyancy and each of limited dimensions to be inserted through the opening in the top of the kayak. The beam units are engaged between the top and bottom walls of the hull, extend longitudinally and centrally of the latter forwardly and rearwardly of the passenger opening and have beam extensions projecting towards each other along the portion of the hull bottom wall opposite the passenger opening. The seat rests on both extensions, is preferably adjustable fore and aft along the latter and also engages the top of the kayak on both sides of the passenger opening to coact with the bow and stern parts in stiffening the semi-rigid hull.

A kayak comprising an integrally molded one piece elongated hull of semi-rigid material and defining a bottom wall, side walls and a top wall which latter has a passenger opening of restricted dimensions relative to said top wall so that the latter extends fore and aft and also laterally from said passenger opening, and an internal frame structure to stiffen said hull, said structure including three separate parts each having dimensions permitting its insertion within said hull through said passenger opening, two of said parts being each an elongated panel-like member positioned in an upright central longitudinal plane within said hull fore and aft of said passenger opening respectively, extending between, contacting and conforming to said top and bottom walls, each of said panel-like members having a beam extension projecting from the end of said member proximate to said passenger opening towards the beam extension of the other panel-like member, both beam extensions extending longitudinally along said bottom wall, contacting and conforming to the same, the third separate part being a seat located within said hull below said passenger opening, having a U-shaped cross-section defining a lower central seating portion resting on said two beam extensions and a pair of upwardly directed side wings extending close to the respective side walls and having upper ends engaged underneath and contacting said top wall laterally of said passenger opening.
