An illustrative embodiment of an enclosed boat trailer may be configured to allow loading of a boat in the water for the purpose of removing the boat from the water using the enclosed boat trailer to engage the boat for storage and/or transportation. An illustrative embodiment of an enclosed boat trailer may be comprised of a roller system positioned on the floor and a right and left rear arm adjacent a rear opening in the enclosed boat trailer. In an illustrative method of use, a boat operator may load and/or unload the boat into the water from the enclosed boat trailer without leaving the boat and without additional personnel.

Disclosed is a system for monitoring the water level proximate to a vehicle. The system comprises a control unit and at least one sensor in communication with the control unit. The at least one sensor is configured such that the control unit can determine a pitch of a trailer coupled to the vehicle and the height of a surface of water proximate to the trailer. The system includes a display screen displaying a representation of the trailer including the pitch of the trailer, and a representation of the surface of water proximate to the trailer.

In one aspect the invention provides a boat support frame loading and unloading apparatus configured to draw a boat on to and off a boat support frame. This boat support frame has a loading end and a terminal end opposite to the loading end. The apparatus provided includes at least one roller assembly mounted to the support frame adjacent to the loading end of the support frame, said at least one roller assembly incorporating at least one roller element. The apparatus also includes at least one drive mechanism configured to rotate one or more roller elements to draw a boat onto and off the support frame through the loading end of the support frame. The roller assembly also includes a hull contact surface formed by a flexible belt which has a circumference greater than the circumference of the said at least one roller element incorporated into the roller assembly.

An alignment guide for a pontoon boat lift that includes a pair of laterally spaced rails, where the spacing corresponds to the spacing between the pontoon floats. The rails are attached to the boat lift by adjustable brackets, so they are positioned at an elevation above the waterline of the pontoon floats, and below the deck that is supported by the floats. A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails.

A trailer frame constructed from a polymer that cannot rust or corrode. The trailer employs a support plate that reinforces an inner and outer wall forming beams that includes a matrix of crisscrossed support walls. A top deck is releasably secured to the frame allowing refinishing of the trailer should the deck be damaged without replacement of the frame. Alternatively the top deck can be a foundation for an enclosure, shield, fence or any other known securement structures.

The present invention is to a self-propelled boat launch and methods of operating components of the boat launch a launch vehicle. The launch vehicle includes a partially submersible generally frame. The frame comprises a front frame unit and a modular carriage frame section, comprising at least one modular carnage frame. The boat launch is self-propelled with track assemblies driven by a hydraulic system powered by an engine assembly. The engine assembly is preferably mounted on top of the front frame unit. At least two track assemblies are in removable communication with a modular carriage frame. A track tensioner is provided for increased tension on a continuous track of the track assembly. A track cleaner is described for removal of foreign objects from at least one track assembly. Further, a method of operating the track tensioner is described. A method of operating the track cleaner is described.

Such a guide apparatus may have the ability to improve the process of loading a boat onto a boat trailer while in the water. It may guide and hold the boat over the desired position on the boat trailer. The ability to instantly adjust and react to different conditions encountered when loading a boat on a trailer and the tall height for improved visibility, makes it a substantial improvement over the submerged rollers and the static rigid guide poles currently available

A composite boat trailer for use in saltwater. The beams, bolts, hangers, fenders, guide poles, suspension, and bunks of the trailer are formed from a composite material that cannot rust or corrode. The trailer employs a manufacturing technique that reinforces all beams to distribute forces anticipated during the movement of a boat on the trailer at highway speeds.
