Abstract: A substantially rigid or semi-rigid chair suitable for white-water use with a hydrodynamically efficient underwater profile, capable of efficient human propulsion, using hands and/or legs, which supports the user in a semi-reclining position and which is sufficiently maneuvrable, in both forward and reverse direction, to enable the user to engage in white-water river use. In one embodiment, the chair consisting of two floats (2, 3), rigid/semi-rigid seat base (4), bow hull floor section (12) an adjustable seat back (8) and a waterproof covering (7). The floats (2, 3) are separated by a rigid/semi-rigid central section (15) comprised of the seat base (4), bow hull floor section (12) which extends from the bow (6) for a majority of the chair's length, and together with the seat back (8) providing a semi-reclining body position enabling the user to use hands and/or legs for propulsion/maneuvring.

Abstract: An inflatable chair suitable for white-water use consisting of two inflatable floats (2, 3), rigid/semi-rigid seat base (4), bow hull floor section (12) an adjustable seat back (8) and a waterproof covering (7). The two inflatable floats (2, 3) are circular in cross section and taper at both ends to conical points (10, 11) at the stern and (13, 14) at the bow (6). The floats (2, 3) are separated by a rigid/semi-rigid central section (15) comprised of the seat base (4), bow hull floor section (12) which extends from the bow (6) for a majority of the chair's length, and together with the seat back (8) providing a semi-reclining body position enabling the user to use hands and/or legs for propulsion/manoeuvring.
