Abstract:
An inflatable chair configured to be primarily propelled by a user's hands and legs, comprising: a hull which is arch-shaped in plan view, wherein the opposing sides of the arch are formed by one or more streamlined, inflatable float(s) and a central semi-rigid section fills the area between the sides of the arch-shape from the apex which forms the bow of the hull, towards the free ends of the arch which form the stern of the hull; and wherein the hull displays a degree of rocker approaching the bow; the lower surface of the central section is a hydrodynamically-efficient shape, describing a smooth, continuous curve from the bow towards the stern and extending to or below the waterline when in use; the upper surface of said central section providing lower and upper-body support for a user, in the form of a seat base between said floats and a seat back adjacent said seat base, said seat back being located between said seat base and the bow; the overall length of the hull being substantially greater than that of the seat base; said hull, said seat base and said seat back being proportioned and dimensioned such that a user sitting on said seat base between the floats with the user's back against the said seat back may immerse his/her legs below the knee while his/her upper body is supported clear of the water surface, enabling simultaneous immersion of his/her lower legs and hands into the water for propulsion and manoeuvring.
