  • Patent number: 11148764
    Abstract: A unique watercraft that includes a plurality of flotation elements which are aligned longitudinally and fit together end to end, comprising the watercraft hull. Unlike other watercraft, it does not rely upon a low center of gravity for stability. A front flotation element pivots about an axis and this pivotal motion is used for both steering and for maintaining balance. The effective profile of the hull changes dynamically as the front flotation element is turned. These hull changes allow the operator to balance and make agile maneuvers. Equilibrium can be easily maintained in this manner when the watercraft is moving forward and when it is otherwise stationary in water. In a preferred embodiment, the watercraft is ridden like a bicycle. Balance is actively maintained by a rider who steers right and left to adjust transverse weight distribution. The riding experience feels similar to operating a conventional bicycle on land.
