  • Self-righting whitewater raft
    Patent number: 6634914
    Abstract: An inflatable raft has an inflatable hull of catamaran type. The hull has parallel spaced fore-and-aft pontoons centrally of its length between elevated transverse bridges at the ends of the hull. The pontoons and bridges are connected by inclined connecting sections. Along a vertical longitudinal centerplane of the hull there is an inflatable righting structure. The righting structure is of inverted V configuration having legs connected at an arm peak above the hull. Lower ends of the legs are connected to the bridges so that the arm extends between the bridges. Inflatable righting sponsons can extend laterally from the arm at its peak area.
