Abstract: An anchoring apparatus includes a resiliently urged cam assembly. Flukes of the apparatus are automatically set in a sea bed engaging position and are releasable for permitting removal from the sea bed. The flukes are then automatically reset.

Abstract: A portable seat for suspension between spaced supports is provided comprising a flexible seating member having rigid side edge members and rigid suspension members spaced outwardly from and generally parallel thereto, the suspension members and the rigid side edge members having securing means adjacent the ends thereof, each side edge member being adjustably secured to its associated suspension member by a length of rope slidably threaded through the securing means so that the spacing between the side edge members and the suspension members can be adjusted by varying the effective rope length, which effective length is maintained by preventing movement of the rope back through the securing means after the desired distance between side edge members and suspension means is achieved. For sway prevention each rope length may be threaded through the securing means to provide both parallel legs and diagonally crossed legs.

Abstract: A buoyant apparatus propelled by a human operator has a pair of side by side annular floats and a pontoon rotatably mounted at the corners of a triangular frame. A pair of platforms are each mounted on the upperside of one of the annular floats. A plurality of paddles are mounted on the undersides of the floats at circumferentially spaced locations. The rotational axes of the floats converge upwardly, and the buoyancy of the floats is such that a person can be buoyantly supported in the water by the apparatus with the outboard portions of the floats raised out of the water sufficiently to result in forward propulsion when the person rotates the adjacent inboard portions of the floats rearwardly. This rotation may be done by the person engaging and rearwardly pushing the inboard portions of the platforms with his or her feet while sitting or standing. Alternatively, the floats may be rotated through a pedal drive operated by the person in a sitting position.

Abstract: An aquatic recreation vehicle susceptible to use by one or a group of passengers or crew has an integrally formed hull having a plurality of surfaces. The hull is symmetrical about a central vertical symmetry plane which essentially divides the hull longitudinally in half. The surfaces include at least three longitudinally extending sections and at least two longitudinally extending pressure ridges. The pressure ridges are symmetrically located on the bottom of the hull and are inwardly directed toward the vertical symmetry plane. At least two longitudinally extending runners are located on the hull to provide high speed planing lift. The hull surfaces are curved upward at the bow to provide smooth entry into the water. A superstructure is located on the hull and extends longitudinally along a portion of the length of the hull. The combined centers of gravity and buoyancy of the hull and superstructure normally lie essentially in the same vertical symmetry plane.

Abstract: The invention relates to a sailboat with a keel board that is inclinable sideways. A single keel board is resiliently inclinable due to the effect of the water which rotates it about an axis disposed substantially in the vertical plane of longitudinal symmetry of the boat and inclined with respect to the horizontal, rising towards the bows of the boat, so as to provide hydrodynamic lift of the inclined keel board compatible with a movement of the boat along its longitudinal axis. In the case of a boat with two inclinable keel boards, the axes of inclination can converge towards the bows of the boat.
