A transport box may be utilized to set down a watercraft into water with a traction mechanism, with a support for securing the traction mechanism for lowering the transport box, and with a frame that is designed to receive the watercraft in the transport box. The transport box is configured to receive an upper side of the watercraft and to set the watercraft down on a lower side into the water.

A cylinder mounting assembly for a hydraulic boat lift includes a plurality of H-frame components for pivotally connecting a pair of bunks to side beams of the lift. A trailing pair of hydraulic cylinder actuators pivotally interconnect the side beams to respective trailing H-frame components. The cylinders are selectively operated to pivot the trailing H-frame components closed such that a first longitudinal channel of each trailing H-frame component receives a respective actuator and an opposite, second longitudinal channel of the trailing H-frame component receivably interengages a respective side beam, which lowers the bunks of the lift sufficiently to facilitate driving a vessel onto and launching a vessel from the lift in shallow water conditions.

Methods and systems described herein can assist a user when loading a watercraft onto a trailer (e.g., at a boat ramp). For example, position data generated by sensor(s) coupled to the watercraft and/or trailer can cause one or more propulsion devices associated with the watercraft to automatically (e.g., without user intervention) position the watercraft onto the trailer, for example, by controlling the power and/or thrust direction of the propulsion device(s).

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 transporting device for launching and hauling boats is provided. The device includes a frame arranged to support a boat hull and is provided with at least two pairs of wheels. Each pair of wheels is formed by two wheels aligned with each other on opposite sides of the frame, and the frame is further provided with one or more tracks. The device is capable of easily and effectively moving both on roads and other hard terrains, and on soft terrains, such as for instance sandy or muddy terrains. According to an embodiment, the wheels and the tracks are mounted on the frame so as to be movable in a direction perpendicular to the plane of the frame itself so that they can be selectively brought into contact with the underlying ground or moved away from ground depending on the kind of terrain on which the device is moving.

A watercraft lift system including one or more laterally-adjustable or rotating components and related methods are disclosed. The watercraft lift system can include a cradle assembly and optionally at least one side guide, which can (but need not) be connected to the cradle assembly. The cradle assembly can include first and second cradle rails. One or both of the first cradle rail and the at least one side guide can be movable between a wider watercraft-receiving position and a narrower watercraft-received position. In an example, movement of the first cradle rail and/or the at least one side guide from the watercraft-receiving position to the watercraft-received position occurs automatically upon entry of a watercraft into the confines of the watercraft lift system. The watercraft lift system can further comprise an actuator to cause lateral or rotational movement, for example, of the first cradle rail and/or the at least one side guide. In an example, the actuator can be operably connected to the first cradle rail and/or the at least one side guide via one or more cables or extension plate members.

A wheel kit for use with a boat lift includes an upper member attachable to the boat lift, and a lower member slidably disposable within the upper member. The lower member contains an axle and a wheel assembly. A braking member includes a base plate with a first side and an opposing second side, a wedge portion outwardly extending from an upper end of the first side, and a tab outwardly extending from a lower end of the first side of the base plate. The braking member slidably disposes upon the axle via an aperture contained within the base plate. When positioning the lower member into the upper member to retract the wheel assembly, the wedge portion of the braking member contacts a closed terminal end of a slot contain within the upper member, outwardly urging the braking member against the wheel assembly to prevent rotation of the wheel assembly.
