20110030606 | MECHANISM FOR ALTERNATIVE POWER OR MANUAL OPERATION OF A YACHT WINCH - A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, which winds and stores the line during line retrieving operations and controllably releases the line when desired. The new winch, while intended to be driven by on-board electric or hydraulic power, includes a novel mechanism, actuated by a conventional winch handle, for converting the winch to a multi-speed manual operating mode in the event of failure of the on-board power system. A clutch mechanism enables controlled release of line from the winding drum during manual operation, and enables adjustments and emergency release operation when operating in a power mode. Novel level wind features enable the lines to be appropriately tensioned during retrieval, and positively drawn from the drum when the line is not under load. Significant improvement in the safety and convenience of the crew is enabled. | 02-10-2011 |

An object that has been salvaged from the seabed can be placed upon the marine vessel. | 05-31-2012 |
20130036962 | MOUNTING METHOD OF THRUSTER - A method for maintenance of a unit which is arranged in a watertight hoisting chamber and closes an opening in a vessel hull is described. The unit is adapted to extend into the water below the vessel. The method includes clamping of the unit in its mounted position by a clamping means so that fixing means of the unit can be removed while the unit is held clamped in position. After the hoisting chamber is flooded to a desired level, the clamping of the unit can be completely released and no unintentional movement of the unit will occur. Guide means may be provided together with the apparatus and an automatic design of the clamping means can also be provided. Especially using such elements, mounting of the unit becomes easy, when the unit is lowered under water to its mounted position, is clamped there by the clamping means so as to tightly close the opening and after removing the water from the hoisting chamber, the fixing means can be applied in a dry environment. Preferably, the clamping means are hydraulic cylinders which press the unit into its mounted position. | 02-14-2013 |

20160059937 | Vessel Recovery System and Method - The disclosure includes a recovery system and method for recovering a deployed vessel having a rotatable support coupled with a stored recovery assembly, including a release unit, line, deployment weight, and drag device on the deployed vessel. A recovery vessel can have a hoist with a coupling element, such as a grapple. For recovery, the recovery assembly can be deployed from the deployed vessel. The drag device can assist in floating and/or maintaining a taut line, especially when the vessel is downwind of the drag device. The coupling element from the recovery vessel can couple with the taut line. Once coupled, the recovery vessel can raise the coupling element with the line, which can rotate the rotatable support to a lifting position above a center of gravity of the deployed vessel. The recovery vessel can then lift the deployed vessel vertically out of the water to a storage position. | 03-03-2016 |
