Abstract
A watercraft in which a beam having a seat for the user is supported by two stanchions pivotally connected to a support frame below the beam. A float elongated in the direction of travel of the watercraft is provided on an upper part of the frame below the beam while a ballast is provided on a lower part of the frame below the float. Between the float and the ballast, lateral arms of the support frame extend for engagement by the legs of the operator who can thereby swing the float and ballast assembly in a balancing operation during travel of the watercraft.
Claims8
A watercraft, comprising:
- a float;
- a support frame attached to said float;
- a ballast attached to said support frame and spaced below said float;
- a pair of upright stanchions spaced apart in a direction of travel and pivotally connected to said support frame between said float and said ballast at a pivot axis parallel to said direction;
- a beam extending in said direction, rigidly connected to said stanchions and spaced above said float;
- a passenger seat on said beam;
- a steering mechanism operatively connected to said beam and effective for steering the watercraft;
- a control on said beam operatively connected to said mechanism for operating same;
- and
- a pair of rigid support arms extending perpendicular to said direction and to said axis from opposite sides of said support frame and rigid therewith for displacement by legs of a passenger on said seat to shift said ballast and float angularly about said axis and relative to said beam and said stanchions.
