A tilting canopy has a canopy frame, at least one actuator, a plurality of canopy supports, and a support frame. The canopy frame is hingedly connected to the support frame through two medial supports, such that the medial supports act as pivot points for the canopy frame. The at least one actuator is engaged between the canopy frame and the support frame such that the at least one actuator is configured to rotate the canopy frame about the pivot point between a lowered position and a raised position. In the raised position, a user may store a boat or other vehicle or item with towers, Bimini tops, or other features which would normally be prohibitive of moving the boat or other vehicle beneath the canopy.

The present invention provides a hammering assembly type fixing device for a shipyard, in which the lower end of a fixture is inserted into a fixing groove formed in a fixing plate (made of a rigid bottom such as steel, concrete, rock, etc.) and the upper end of the fixture is screwed to be coupled to a separate fastening element, such that a grating, a work foothold, etc. are fixed. The hammering assembly type fixing device for a shipyard according to the present invention is configured such that a protruding flange inclined downward is integrally formed with a fixture to form a single body at a portion where an upper end and a lower end of a fixture are connected to each other, and a packing ring is provided to be inserted into the lower end of the fixture in close contact with the protruding flange. As such, as the fixture is fixed to the fixing plate by the pressing from the hammering, the hammering assembly type fixing device has the characteristics of being resistant to lateral forces and preventing breakage of the lower end due to a primary fixing by the lower end and a secondary fixing by the protruding flange. Further, the pressing force of the protruding flange of a downwardly inclined structure, and the improved sealing property by the packing ring, and the excellent foreign substance blocking effect are obtained. Moreover, the manufacturing process of the fixture is simplified, thereby reducing the manufacturing cost. Especially, the hammering assembly type fixing device for a shipyard is applied to fix a grating installed in a shipyard, so that even in high salt conditions due to the inflow of seawater through various routes in shipbuilding processes, the fixing force of the fixture with respect to the fixing plate is maximized and the airtightness by the packing ring is improved, thereby preventing the occurrence of fine gaps between the fixing plate and the fixture. Therefore, the penetration of salt is blocked, thereby preventing the corrosion of the fixture and improving durability of the fixture.

A boat lift includes four posts and four linear actuators, each attached to one of the posts. Each linear actuator includes an extendable and retractable member oriented for extension and retraction substantially parallel to the post. Ends of a first pair of the extendable and retractable members are connected to a first carrier and ends of a second pair of the extendable and retractable members are connected to a second carrier. A cradle or platform is supported by the first and second carriers. The boat lift may be supported by the ground, by a structure, for example, a dock, a sea wall or a wall of a boat house, or by pontoons.

A barge, a barge assembly system, and assembly method are provided for assembling a barge that is constructed in component pieces sized to be capable of shipping by road or railway from a first location to a second location adjacent to a body of water for assembly of the barge. The barge assembly system includes a portable assembly device having a variety of frame elements that, when assembled, produce a structure capable of supporting barge section components that are placed thereupon so that the barge may be assembled. The barge assembly system can also include a crane for lifting the barge section components onto a support surface of the portable assembly device.

A jack-up platform is described having a horizontal working deck that may be jacked up out of the water by moving its legs to a position wherein they take support on an underwater bottom. The jack-up platform further comprises a mooring system for mooring a floating vessel at a mooring side of the jack-up platform. The mooring system comprises an elongated support means for supporting a hull part of the floating vessel, and guiding means connected to the hull of the jack-up platform at the mooring side. The guiding means are able to rigidly hold the elongated support means in a support position, in which the elongated support means is within reach of the hull part of the floating vessel to be supported when the hull is jacked out of the water and the jack-up platform rests on its legs. A method for mooring a floating vessel using the jack-up platform is also described.
