A system for supporting a motor of a boat with respect to a boat trailer is provided. The system includes a support member, a trailer connector constructed and arranged to be releasably attached to a portion of the boat trailer, and a motor support constructed and arranged to frictionally engage portions of the motor of the boat. The motor support includes a base member, a first and a second hinge members extending from spaced locations on the base member, and a first and a second clamp members. The first and second clamp members are pivotably connected with the first and second hinge members, respectively. The first and the second clamp members, and the first and the second hinge members are adjustably cooperable to receive and engage opposite sides of the motor, and to facilitate engagement of the front of the motor with the base member.

A system for supporting a motor of a boat with respect to a boat trailer is provided. The system includes a longitudinally extendable support shaft that is configured to be secured in a selected one of a plurality of extended positions, a motor support disposed at a first end of the support shaft; and a boat trailer connector disposed at a second end of the support shaft. The trailer connector includes a releasable latch to connect the trailer connector to the boat trailer. The trailer connector includes a manually enagageable actuator configured to selectively latch or release the trailer connector from the boat trailer.

An amphibious transport apparatus includes forward and aft ends, a pair of spaced apart pontoons including tracks, and a transversely extending structure, which can include a platform, that spans between the pontoons and connects the pontoons together. The amphibious transport apparatus further includes a sled vessel that can be used to transport materials or personnel. The sled can be releasably attached to the amphibious transport apparatus with tow bar and a pivotal connection. Said tow bar can be rotatable between an upper storage position wherein the tow bar engages the vessel away from said pivotal connection and above a terrain surface, and a lower towing position. A towing position of said amphibious craft and sled can be defined by the sled connected to the amphibious craft at the releasable pivotal connection, with the amphibious craft being self propelled with said tracks for engaging the underlying terrain and with the sled in the lower towing position so that the sled bottom drags along on the underlying terrain during movement of the amphibious transport apparatus and sled. A trailer for loading and unloading the sled can also be provided. The amphibious craft can push the sled onto the trailer during loading.

A structural cross frame connector is described having a multipurpose system of attachment. The device has two main forms one with a vertical offset and one without this vertical offset. The central portion has an arch by which weight is distributed accordingly. The connectors have a group of pass through holes whereby a pass through rod is attached thereto using fasteners. Various structural members can be attached to the pass through rod using pass right and left pass through cavities typically used as structural support members and a central pass through cavity typically used as a hitching station. Leaf springs are also mountable on pass through rods and freely operate on another connector right and left pass through cavity for use as a suspension system.

Methods and apparatus are disclosed herein that determine a vehicle backup position for launching and loading a boat using trailer hitch load. An example apparatus includes a data analyzer to determine, based on a trailer hitch load of a vehicle coupled to a trailer, a vehicle backup position for launching the boat at which a boat coupled to the trailer is floating on a body of water and an instruction generator to instruct a braking system of the vehicle to stop the vehicle at the vehicle backup position for launching the boat.

A rotatable support structure for supporting elongate objects, comprised of a first support structure, a second support structure, a rotatable axle, a first hub, a second hub, a plurality of first elongate support members, an equal number of second elongate support members, and a locking mechanism, where the first support structure and the second support structure support the rotatable axle, the first hub is affixed to the rotatable axle and supports the first elongate support members, the second hub is affixed to the rotatable axle and supports the second elongate support members, corresponding pairs of the first and second elongate support members support elongate objects attached thereto, and the locking mechanism prevents the rotating axle from rotating and allows the rotating axle to rotate to allow the elongate objects to be conveniently loaded and unloaded from the rotatable support structure; whereby the rotatable support structure may be configured as a watercraft transportation trailer.

A hitch assembly includes a support extendable into a receiver tube attached to a vehicle. A sleeve has a top end and a bottom end. A bracket is attached to the sleeve and is attached to the support to vertically orientate the sleeve. A piston is positioned in the sleeve and extends outwardly of the bottom end. The piston has a lower end that is moveable toward or away from the bottom end. An actuator is mounted on the sleeve and is mechanically coupled to the piston. The actuator is actuated in a first direction to lower the lower end and actuated in a second direction to raise the lower end. A ball mount is removably attached to the piston adjacent to the lower end. A hitch ball is attached to the ball mount and engages a hitch coupler of a trailer.

The powered kayak storage rack comprises a kayak lifter that may be coupled to the front of a car hauler trailer. The kayak lifter may be operable to transport one or more kayaks. The kayak lifter may be operable to elevate the one or more kayaks above a trailer deck of the car hauler trailer such that one or more hauled vehicles, cargo, or both may be carried on the trailer deck beneath the one or more kayaks. The kayak lifter may comprise an upright support and a rack. The upright support may be a vertically oriented structure that couples to the front of the car hauler trailer. The rack may be a carrier for the one or more kayaks. The rack may be pivotably coupled to the upper half of the upright support.
