Abstract: After a wire rope sling is fabricated and the sleeve has been painted and dried, an adhesive type of tag containing all of the information required by ASME B30.9c is applied directly to the sleeve's surface. The sleeve and the tag will then be encased using a transparent casing, coating, or sealant. This will protect the tag from abrasion, the environment, and will ensure a permanent and legible tag.

Abstract: A fin assembly for adjustably coupling a fin (2) to a board (16). The fin assembly includes a fin having a base (6), the base including a substantially semicircular portion (13) and a front tip (12). The fin assembly also includes a fin box (1) adapted to be attached to a board, the fin box having an opening (3) for receiving the base of the fin. A rear end of the opening has a substantially semicircular portion (5) for receiving the semicircular portion of the base.

Abstract: A retractable-airfoil vessel has surface-effect wings (1) that are hinged or otherwise attached extendedly to a vessel (3). The surface-effect wings are extendable to a use mode in proximity to a surface of water (5) at sides (2) of the vessel for surface-effect lift of the vessel at elevated speeds. At low speeds when pleasure cruising or fishing, when stopped for water activities or when adjusting to rough waters and storm conditions, the surface-effect wings can provide wide-area buoyance on water at sides of a center of gravity of the vessel. The best of all worlds, it can be made to ride-out a storm as safely and securely as an anchored buoy and yet have high-speed efficiency, low-speed pleasure cruising and stopping for swimming and marine exploration. Then for docking in vessel slips and for maneuvering in close proximity to docks and harbor structures, the surface-effect wings can be retracted onto the vessel in a non-use mode for non-interference storage and for docked-living shelter.

U.) material, while the core layer is made from the close cell of ethylene-vinylacetate copolymer (E. V.

Abstract: In a method of and apparatus for offshore mooring, a clamping apparatus includes a clamping mechanism and a pulley. A mooring line connected to an anchor or a pendant line connected to a vessel to be moored extends through the clamping mechanism and around the pulley of the clamping apparatus. The distal end of the line extending through the clamping apparatus is connected to an anchor handling vessel. The anchor handling vessel is employed to apply a predetermined tension to the pendant line and the preset mooring line. A remote operated vehicle is then employed to actuate the clamping apparatus and to disengage the anchor handling vessel.

Abstract: A mooring arrangement between a floating storage body spread moored in deep water and a shuttle tanker, the arrangement including a single point buoyant member that is adapted for mooring a shuttle tanker in offloading position relative to a floating production, storage and offloading vessel (FPSO) with a link between the floating storage body and the single point buoyant member. One embodiment (100) of the invention employs a submerged yoke (30), having one end (31) rotatably coupled to a FPSO (10) and a second end (32), supported by a buoy. A mooring hawser (28) extends from the buoy to the shuttle tanker and product hoses connect the shuttle tanker with the FPSO and extend along the submerged yoke.

Abstract: A rigid concavity is formed in the underside of a hull of a water craft. Air enters into the concavity when the water craft is moving forward. Supplemental air is introduced into the concavity by an air scoop mounted to the bow. A one-way valve in an air passageway between the air scoop and the concavity prevents air from flowing from the concavity to the air scoop. A first stern plate mounted at a slight downward angle causes air to flow under the stern in the form of small bubbles and increases the back pressure presented to the flow of water and air through the concavity. A pair of adjustably mounted stern plates may also be provided on opposite sides of the motor to control the amount of back pressure. The airflow through the rigid concavity reduces drag so that the water craft can travel at higher speeds.

Abstract: A marine vessel is provided having a stern drive attached to the transom of the vessel. An actuator is provided for adjusting the pitch of the stern drive relative to the transom of the vessel. The stern drive is mounted on the transom of the vessel such that a driveshaft driven by the engine of the vessel and passing through the transom to enter the stern drive does so above the waterline of the vessel. Furthermore, the actuator is of a sufficient length to allow the pitch of the stern drive to be adjusted to such a degree that the entire stern drive can be brought above the waterline of the vessel. To this end, the actuator may be disposed between the transom of the vessel and a cantilevered member attached to the stern drive.

The sponsons are each pivotally connected to the main hull by means of a pair of respective arms which together with the sponson and the hull define a parallel type four bar linkage. The sponsons stabilise the vehicle on water and are readily stowed to allow vehicle mobility on land.
