Abstract: A novel water ski binding clamps tongue, heel, and reinforcing strips to a sole plate with screws normal to the edges of the plate. Thus the strips initially extend substantially vertically from the edges rather than substantially horizontal (parallel to the mounting plate) as in the prior art.
Abstract: A portable device for closing a breach in a boat hull from the inside or the outside which includes an inflatable shallow dome sortable in a cylindrical form and automatically inflatable by the use of a self-contained cartridge to cause expansion into a non-buoyant shallow dome which can seal against a hull breach and enable a damaged boat to reach port.
Abstract: A sailing craft of the type which includes a floating hull, a mast secured to the hull, a sail mounted on the mast and rudder means, wherein the mast is pivotally mounted with an articulation near but spaced from the base thereof with respect to a substantially horizontal axis, and a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and a linkage interconnecting the mast and the mobile fins for actuating the fins such that they act in the water in a manner so as to tend to right the hull under the dynamic action of water on the fins in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of the wind to which it is exposed.
Abstract: An outrigger device attachable to a flying bridge or a tower leg, comprising a hollow tubular member which is connected to the flying bridge or tower support member. The hollow tubular member has its proximal end connected to a system of brackets which allows pivotal movement of the tubular member about multiple axes. The system of brackets is connected to the flying bridge or tower support member, and includes a collapsible brace member connected between the support member and the tubular member. The system of brackets also includes a singular brace member connected between the flying bridge beneath the support member and the tubular member. When not in use, the outrigger device may be folded compactly against the flying bridge or tower leg adjacent the support member and held in place by a spring locking clamp.
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: A rotatable energy-absorbing sleeve unit for ship bumpers including a rim-free vehicle rubber-containing tire carcass filled with elastomeric foam. The elastomeric foam may be either polyurethane or rubber foam. The tire may be an auto or truck new, used, retreaded or blemished tire.
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.
Abstract: The invention relates to a suction dredge barge in which the air chambers (8,9) on either side of the hold (2) can be filled with mud via an overflow (14) at the top edge of the hold (2) said air chambers (8,9) having inclined bottoms (10,11) and discharge openings (12,13) towards the hold at the lower edge of said inclined bottoms (10,11).
Abstract: A variable inlet for a marine jet propulsion system comprising a movable lip, a center splitter serving to divide said inlet into upper and lower passages and coupled for movement proportional to that of said lip to assure equality of the areas of said upper and lower passages, and apparatus for varying the outward projection of said splitter to vary the diffusion ratio of said upper and lower passages.
Abstract: Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be connected to a boat transom, a stern bracket having an upper end, a first pivot connecting the upper end of the stern bracket to the transom bracket for pivotal movement of the stern bracket relative to the transom bracket about a first pivot axis which is horizontal when the transom bracket is boat mounted, a swivel bracket, a second pivot connecting the swivel bracket to the stern bracket below the first pivot for pivotal movement of the swivel bracket relative to the stern bracket about a second pivot axis parallel to the first pivot axis, a propulsion unit including, at the lower end thereof, a rotatably mounted propeller, a third pivot connecting the propulsion unit to the swivel bracket for steering movement of the propulsion unit relative to the swivel bracket about a generally vertical axis and for common pivotal movement with the swivel bracket in a vertical plane about the first and second horizontal axes, and
