An improved trailer chassis assembly primarily constructed from extruded components including an extruded chassis rail component, a cross member component and a connector component. The component has a wall surface defining an interior channel and an opening in the wall surface extending through the wall surface to the interior channel. The connector component has a first region adapted to engage with the interior space of the chassis rail component, and a second region adapted to engage with the cross member component. The interior space of the chassis rail component is adapted to capture movement of the first region of the connector component in vertical and horizontal planes, and yields movement in the axial plane.

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 method that uses a tool specifically designed for removing weeds, milfoil, invasive species, or any other foreign matter from boat, pontoon, personal water craft trailers, dock, boat lift and the like. The tool incorporated within this method of removing weeds and the like from watercraft trailers is able to cut weeds in half or scrape weeds that are hanging on trailer beams allowing them to fall to the ground. It can hook or grab weeds pulling them off trailer beams. The tool can slide on trailer beams capturing weeds in the tool head, which can then be removed when the tool head is taken off the trailer beam. A rotating handle is incorporated allowing ease of use from many different angles.

A portable trailer wheel rinsing system comprises at least one liquid storage tank configured to be attached to a trailer, a plurality of spray nozzles configured to be attached to the trailer and direct a liquid spray onto a wheel assembly of the trailer. The plurality of spray nozzles are in fluid communication with the at least one liquid storage tank and a pump is in fluid communication with the at least one liquid storage tank and the plurality of spray nozzles. A timer may be included and be in electrical communication with the pump. The timer is configured to activate the pump for a predetermined amount of time and the pump is configured to pump a liquid from the at least one liquid storage tank through the plurality of spray nozzles such that a liquid spray is applied to the wheel assembly for the predetermined amount of time.

Various examples of transferring a watercraft between land and water are disclosed. When a vehicle receives a transfer signal, the vehicle locates a launch ramp, and the vehicle moves to the launch ramp. A trailer attached to the vehicle moved into the water using the launch ramp, such that a watercraft can be transferred between land and water via the trailer.

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.

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.

Pontoon forks are specifically designed for the marine industry to efficiently and safely lift and maneuver pontoon boats. The pontoon forks are engineered to lift tri-toons and pontoon boats of lengths up to and greater than twenty-eight feet. The forks can further accommodate weights of up to and greater than six-thousand pounds. Removable pockets included with the pontoon forks allow for the lifting and transport of pontoon boats of various sizes without having to have specialized equipment for each and every make and model of the pontoon boat. The pontoon forks are retrofit to fit specific forklifts already owned or easily acquired by marinas.

A boat trailer constructed from a polymer composition that cannot rust or corrode in salt water. The trailer employs a support plate that reinforces an inner and outer wall forming beams that includes a matrix of crisscrossed support walls.

A boat securement alerting apparatus may include a sensing assembly for sensing existence of a securing condition of a boat securing apparatus. The sensing assembly may include a sensor device with an actuator being movable between an actuated position and a released position. A portion of the actuator may be positionable adjacent to a movable securing element of the securing apparatus such that the actuator is actuated when the movable securing element is moved to a securing position corresponding to the securing condition of the boat securing apparatus. The alerting apparatus may further include an alerting assembly configured to produce an alert when the sensing assembly senses the existence of the securing condition of the boat securing apparatus, and the alert may be a perceptible alert perceptible to a sense of a human.
