Embodiments of a floating bunk system of this disclosure include a hull pad assembly extending in a longitudinal direction and including two hull pads spaced apart from one another and, at each end of the hull pad assembly, a sliding guide assembly including a pair of guide poles, each guide pole of the pair extending in a vertical direction; an upper end channel extending in a lateral direction and connected to the hull pad assembly and to the pair of guide poles; a lower end channel extending in the lateral direction and including a pair of lower bushings; each lower bushing receiving a respective guide pole; the upper end channel being in a fixed position relative to the pair of guide poles; the lower end channel being slidably vertically displaceable along the guide poles toward and away from the upper end channel.

There is provided a storage system for storing and retrieving watercraft or other items to or from a storage position in a storage area as part of an enclosure having a plurality of storage areas. The storage system may include at least one carrier to support the item during movement to or from a storage position, and a positioning system to move the carrier system. An elevator system is usable to move the positioning system and carrier system to and from a storage area, and a control system is usable to control the positioning system to move the carrier system and item into and out of its storage position.

A shipyard including a shiplift platform that is capable of being raised above yard level for maintenance is provided. Hoists are coupled with the shiplift platform, and jacks are coupled with the hoists. The jacks are capable of lifting the hoists relative to the yard, and are capable of lifting the shiplift platform above the yard level.

An automated system is provided for moving a boat from a storage position in a boat garage to a deployed position in a dock channel. The system can include a boat trolley. The boat trolley can include a frame that couples to and rides on rails of a track that extends between the boat garage and the dock channel. The boat trolley can also include bunker supports for supporting the hull of the boat. A dock lift mechanism can lower the trolley frame into the water, from which the boat can be deployed. Once done using the boat, the user can navigate the boat onto the trolley frame, and the dock lift mechanism used to lift the trolley frame and boat out of the water, and the boat trolley operated to move the boat from the dock to the boat garage for storage.

A boat lift for raising boats out of the water to facilitate maintenance and to reduce corrosion and contamination. The boat lift includes two or more boat lift assemblies positioned and spaced apart so that each boat lift assembly lifts approximately the same fraction of the overall weight of the boat. Each boat lift assembly has a lifting structure with bunk cushions mounted on pivoting bunk bases to prevent damage to the boat hull when lifting. Hydraulic lift mechanisms are enclosed within each boat lift assembly providing a cleaner appearance as well as protection against corrosion and fouling. A dual-pulley mechanism enables lifting distances substantially larger than the length of the lift mechanism. A hydraulic control system ensures that all the boat lift assemblies move up and down simultaneously and at the same rate, thereby maintaining the boat horizontal at all lifting positions.

A bunk mounting system for a watercraft lift comprising a first support defining first and second legs, a second support defining third and fourth legs, and first and second bunks. The bunk mounting system has first and second crossbeams, pivot connectors, and rail connectors. The pivot connectors pivotably connect the first crossbeam to the first and second legs and the second crossbeam to the third and fourth legs. The rail connectors detachably connect the first bunk to the first and second crossbeams and the second bunk to the first and second crossbeams.
