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.

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 watercraft lift with hydraulically actuated arms which self-installs a fitted three-dimensional watercraft cover on a powerboat. A mechanism enables a linear actuator to drive a swing arm up to 180 degrees. The upper end of a two part arm articulates mechanically as the arm moves to reduce vertical elevation while operating. A spring-tensioned elongated roller keeps the cover tight and self-rolls the cover on the elongated roller when the actuated arms are pivoted forward. The mechanism can be attached to the guides of most watercraft lifts.

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 covering system for removably covering a vehicle, such as a boat, that includes a plurality of rotatively anchored swing arms rotatable between a covered position and an uncovered position. Each swing arm includes a mount and a pretensioner formed of one or more stays adjustably attached to part of a shaft of the arm to adjust an applied preload and transfer forces encountered during operation to part of the shaft rotatively anchored by the mount to a grounded structure such as a piling or post of a dock. The swing arms are pivotally connected to an elongate transversely extending carriage from which a cover is suspended with a boom of each arm connected to the carriage by a pivot assembly that also facilitates carriage and cover position adjustment. A pivot limiter can be included that limits or even stops pivoting of the carriage relative to the swing arm boom.

A system for use with a Luxury Boat, when the Luxury Boat is in Temporary Dry Storage involves a sensor is configured to sense a trigger signal from a boat-based pump controller indicating that raw water is to be pumped to at least one Auxiliary System and send a signal to a second controller that will cause the second controller to start a pump, external to the Luxury Boat, pumping antifreeze from a reservoir to at least one Auxiliary System on the Luxury Boat in Temporary Dry Storage. An associated method is also disclosed. A system involving a a raw water collar that forms a seal against a hull of a Luxury Boat about a scoop strainer of the Luxury Boat through which raw water can be supplied when the Luxury Boat is in Temporary Dry Storage is also described.

A universal and rapid system suitable for covering boats or any other vehicle and object. The purpose is to realize a covering system which is practical, functional in the positioning phase and compact in storage, to overcome problems related to water stagnation and bad air circulation, and to get the advantage of waterproofing, of protection from atmospheric agents. The system comprises a cover (1), a coupling means (10) placed on it, a system for lifting (38) anchored to a support structure (39) wherein said cover (1) is connected to a sleeve (15). The system, in its several applications, diversifies itself for the various possible embodiments of the several elements constituting the system, for example for the type and shape of the cover, for the type of the sleeve, for the modalities of anchoring.

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.
