  • Patent number: 10501161
    Abstract: A ship steering device including: an engine; an auto-drive unit that exerts propulsive power on a ship hull by power from the engine; detection means for detecting a current position and an orientation of the ship hull; a ship steering control device that controls an output of the engine and propulsive power of the auto-drive unit; and a calibration switch that starts calibration of a ship. When the ship steering control device detects that the calibration switch is turned on, the ship steering control device controls the engine and the auto-drive unit to cause the ship hull to move in a predetermined direction or to turn, and if a difference between, for instance, a traveling amount and speed in the predetermined direction and an intended traveling amount and speed exceeds a predetermined value, the ship steering control device corrects control values of the engine and the auto-drive unit.

  • Patent number: 8060265
    Abstract: There is provided a boat (200) including a hull (20), and two engines (30, 50) couplable to rotationally drive mutually spaced separate corresponding propeller assemblies for providing thrusts. Directions of the thrusts are angularly adjustable (?1, ?2) relative to the hull (20). A control unit (70) receives first and second user commands (S1, S2) and sends corresponding signals for controlling powers (P1, P2) coupled from the engines (30, 50) to their propeller assemblies. The control unit (70) determines a difference in power (?P) to be coupled to the propeller assemblies as a function of the first and second user commands (S1, S2). The control unit (70) controls coupling of power (P1, P2) to the propeller assemblies so that the propeller assemblies develop a difference in thrust which is a function of the difference in power (?P).

  • Patent number: 7344377
    Abstract: A method, a system and a device used within such enhances the repeatability and overall performance of a person skiing through a water ski slalom course. The device is a series of markers positioned on the side of a ski boat which markings can be readily viewed by a skier being towed by the boat at a distance of up to about 100 feet. The method comprises having the skier noting the boat markings which the ski rope crosses as the skier begins a turn into the slalom course. Once a run of desired performance is obtained the skier can repeat that performance more readily by always beginning the initial turn into the slalom course based on the ski rope crossing the same marking on the boat.

  • Patent number: 5623975
    Abstract: A cylindrical plug made of elastomeric material is introduced into a cylindrical cartridge. The rim of the cartridge is swagged-in to reduce the diameter of its opening to one-third of the cartridge internal diameter and of the closely matching plug external diameter. The cartridge is held in a chamber. A tube slidingly passing through the wall of the chamber comes in contact with the plug, and holds it within the container while the chamber is filled with a highly pressurized fluid. As the cartridge is filled with the pressurized fluid the plug is tightly held against the internal end of the tube. The tube is partially withdrawn drawing the plug against the swagged opening of the cartridge. As the tube continues to be withdrawn its internal open end is separated from the plug, and pressurized fluid begins escaping through the tube indicating that the cartridge is filled. The pressurized fluid can now be evacuated from the chamber.

  • Patent number: 4479287
    Abstract: In reinforcing an eye hole for roping of a sheet-like article by setting grommet metal fittings therein, there is formed an incised hole nearly equal in diameter to the outer diameter of the cylindrical portion of a male grommet, and the tongues covering the incised hole, which are made through a process of radially incising at a position where the eye hole for roping is to be provided on the sheet body, in place of a circular through-hole heretofore in use. Each of the tongues and the peripheral region of the incised hole are pressed together while being enfolded by the grommet metal fittings being depress-deformed through a suitable means, thereby leading to reliably and strongly setting of the grommet metal fittings and increasing the tensile strength of the eye hole for roping.

  • Patent number: 4444144
    Abstract: In the depicted embodiment, the jib shackle comprises a two-section body having converging arms extending therefrom. The sections of the body are relatively rotatable, about the axis of the body, to move the converging limbs into and out of proximity with each other. When the limbs are put into proximity, they define a closed loop with the body, and when moved out of proximity, open the loop. Ends of the body are apertured to receive therethrough a line (rope, hawser, etc.) which may be knotted, within the loop, to prevent its withdrawal from the shackle. Ends of the limbs which are remote from the body have complementary configurations which cause such ends mutually to nest with each other, upon being closed upon each other, to define the surfaces of the loop with substantially no discontinuities or abrupt edges. The novel shackle is formed of rigid plastic, hence on shipboard use it will not mar or otherwise abuse wooden or fiberglass boat surfaces.

  • Patent number: 4357889
    Abstract: Sail handling apparatus comprises an elongate guide element, e.g. a rod or a cable, located along a path along which a tie locating an edge portion of a sail is required to move during sail handling operations. The tie is attached to the guide element by a load-transfer device comprising a pair of rotatable recessed wheels having a guide member located between them at the periphery of the wheels. When the tie is moved along the guide element it can pass intermediate attachment members supporting the guide element with such members being received in the recesses in the wheels which then rotate with respect to the guide element to pass the attachment members through the load-transfer device. In other embodiments, the load-transfer device forms part of the intermediate attachments for the guide element to enable the sail securing ties to pass such attachment points.

    Abstract: A spring biased snap hook having a body fabricated from a developed sheet metal blank. The body has a pair of recessed areas extending inwardly from one edge thereof and this one edge also includes locking member receiving areas spaced longitudinally therealong. An elongated locking member is received in these receiving areas and is longitudinally movable along the one body edge between a first position blocking access to both recess areas and a second position providing access to one of the recessed areas. A spring bias continuously urges the locking member toward the first position. A handle or keeper member is releasably affixed to the outermost end of the locking member to retain this member in operable association with the body. Removal of the handle or keeper permits the locking member to be moved longitudinally along the one body edge in a direction opposite to the movement thereof from the first to the second position in order to provide selective access to the other of the recess areas.
