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.

The present invention is a personal watercraft lift and transporting cart. In particular, the present invention is directed to a lift that can lift and rotate a personal watercraft (PWC) so that repairs can be conducted more ergonomically. The lift preferably has two lifting arms attached to upright frame members. In turn, the upright frame members extend vertically from a mounting base. The lift also preferably has two actuators pivotally attached to the lifting arms at one end and attached to the mounting base at the other end. When the actuators extend, the lifting arms lift and rotate. The transporting cart preferably has a cart chassis, a hull bunk and two receivers, where the first and second receiver are spaced to allow insertion of the first and second lifting arms so that the cart can be lifted and rotated by the lift with PWC mounted on the cart.

Storage racks for personal watercraft are provided for installation on standard boat dock posts. The storage racks may be pivotally attached to a post such that the storage rack may be pivoted between an over-dock orientation, a stowed orientation and an over-water orientation. A storage rack may be installed and reoriented without use of tools or additional hardware.

A transportation platform for an underwater towing device, including: a main frame; a support frame; a movable base; operation decks; ladder stands; and main lifting lugs. The main frame includes upright posts, basal tubes, longitudinal tubes, transverse tubes, and diagonal tubes. The support frame includes cushion blocks, transverse beams, stand columns, carrier bars, and stiffeners. The ladder stands include stand pipes and a plurality of deformed bar. The main lifting lugs are disposed on the upright posts of the main frame. The support frame is in the form of a door frame and disposed in the lower part of the main frame. The carrier bars cross over the basal tubes. The stiffeners are disposed between the upright posts of the main frame and the transverse beams. The cushion blocks are disposed on the carrier bars. The movable base is disposed between the carrier bars of the support frame.

A boat lift drive for connection to a winch having a winch shaft. The boat lift drive includes a power unit, a drive train engaged to and being driven by the power unit, and a drive shaft engaged to and being driven by the drive train. The drive shaft in turn is engaged to and drives the winch shaft. The drive train includes a seat with a frustoconical section and the drive shaft includes a head with a frustoconical section. The frustoconical sections are press fit into each other. This frustoconical engagement provides a great amount of torque for lifting boats.

A removable rack for holding and/or transporting kayaks with a vehicle such as a pick up, trailer, utility vehicle or flat bed truck. The rack comprises a frame which holds at least one kayaks in a pickup at a selected height and leaving storage room under rack frame. The rack also can be disassembled into a relatively small bundle of parts for easy storage and transport. The rack provides a dolly or hand truck including a frame with wheels and a handle means to maintain the desired spacing between the support surface and the kayak supported by the elevated platform. The hand truck assembly are configured to be easily moved onto an elevated platform, for example, the bed of a truck or an elevated floor such as a raised patio or deck floor. The transport device facilitates transportation of the kayak to a body of water.
