20110188931 | Small boat dock racking system - A small vessel dock racking system provides a three-sided cradle that is rotatably connected to two lateral supports extending outward from one side of the dock. A person in the water can float the canoe or kayak into the cradle and lift it into a secure vertical storage position on the side of the dock without having to get up on the dock. A pivot point extending out into the water has the advantages of both accommodating freeboard and minimizing the distance between the pivot and the boat's center of gravity, thereby allowing for much less effort in lifting. Depending on the depth of the vessel, the cradle can be dimensioned so that the position of the vessel's center of gravity tends to hold the cradle in a vertical alignment after it's been lifted. Where needed, a cradle latch that can be activated from the water side further secures the storage position. | 08-04-2011 |

20150125207 | YACHT LIFTING APPARATUS - The present invention relates to a yacht lifting apparatus. To transport a ship being lifted at a quay or a dock on the coast in a safe manner without vibration, the present invention proposes a yacht lifting apparatus which comprises: a main body frame standing upright at both sides of the ship to support a load and having a bottom comprising a wheel; lifting means arranged above the main body frame for enabling the elevation of a band wound onto the ship; and control means for controlling the operation of the yacht lifting apparatus, the yacht lifting apparatus being configured to transport and lift the ship to a predetermined place, said yacht lifting apparatus further comprising: a first cylinder arranged below the main body frame toward the hull of the ship; and hull fixing means for preventing the ship from vibrating by allowing a contact element coupled to the front end of the first cylinder to contact the hull. | 05-07-2015 |
20150321730 | WATERCRAFT LIFT AND AUTOMATIC WATERCRAFT COVER - A boat lift with hydraulically or mechanically actuated arms which self-installs a fitted three-dimensional boat cover on a powerboat. The control logic of the system allows for cover operation only when the lift is raised. A spring-tensioned roller keeps the cover tight and self-rolls the cover on the roller when the actuated arms are pivoted forward. The roller is hidden behind the boat in ‘cover-on’ position. A slip clutch prevents the torsion spring from being over tightened. The forward position of the roller is adjusted by adjusting the hydraulic cylinder length. The rearward position of the roller is adjusted by limiting the retracted position of the hydraulic cylinder. A non-hydraulic embodiment actuates the cover when the lift is operated. | 11-12-2015 |
20150336775 | HOISTING SYSTEM AND ACCOMPANYING CONNECTOR CATCH ASSEMBLY - A hoisting system, including: a hoisting crane including a hoisting cable, a craft, and a connector catch assembly for interconnecting the hoisting crane and the craft or a load/cargo on the craft. The connector catch assembly includes: a connector body, and a connector catch having a funnel-shaped trap-cage, whereby one of the connector body and the connector catch is attached to the hoisting cable and the other of the connector body and the connector catch is attached to the craft or the load on the craft. A wide side of the funnel shaped trap-cage is directed toward the connector body on approaching one another, whereas an opposite narrow side of the funnel shaped trap-cage has the connector catch mounted therein for releasably holding the connector body. | 11-26-2015 |
