A boat loading guiding system includes a trailer including a frame having a front end, a rear end, and a longitudinal axis extending through the front and rear ends. A mount is attached to the frame and is aligned with the longitudinal axis. A horizontally orientated axle is attached to the mount and is orientated perpendicular to the longitudinal axis. The axle extends through each of a pair of arms adjacent to their first ends. The arms extend toward the front end and are pivotable to form an angle with respect to a top side of the primary support between 85 and 5. A guide roller, for engaging a keel, extends between and is rotatably coupled to the arms adjacent to their second ends. A biasing member biases the second end of the arms upwardly above the top side of the primary support and toward a deployed position.

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.

A trailer designed to be lowered and raised in shallow water to launch a boat or any other type of watercraft. The lowering and raising of the entire trailer is accomplished by (1) the front end of the trailer transforming the tongue and extension of tongue from a substantially straight alignment to a bent alignment by hingedly rotating the extension of tongue in relation to the tongue as facilitated through the use of a first elongated lever or rod and gravity, (2) the rear or back end of the trailer providing a rotation of an extension about the wheel hub to the wheel using a tube surrounding a rear axle that is actuated through the use of a second elongated lever or rod, and (3) all of this being accomplished at the same time from the interaction of the first elongated lever or rod and the second elongated lever or rod through a second arm located at a transitioning hub.

A bow stop 20 including a Vee portion 25 having a front, bow engaging concave surface 26 and rear surface 27. The bow stop 20 further having a connection portion 28 for connection to a trailer 11. The Vee portion 25 has a rigid body or chassis (hereinafter body) 70 and a polymer cover 71, and the polymer cover overlies a front, Vee-shaped surface of the body 70. The connection portion 28 is configured for positioning between a pair of spaced apart and generally parallel upstanding arms 36 of a bow stop support structure 17 of a boat trailer 11 and the connection portion 28 includes a connector 38 for connection to the upstanding arms 36.

A boat trailer configured to provide the coordinated hauling of a plurality of boats having associated trailers. The boat trailer includes a lower platform and an upper platform that are operably coupled by a plurality of support members. The plurality of support members are operable to provide height adjustment intermediate the upper platform and lower platform so as to accommodate loads of different sizes. The upper platform and lower platform include opposing longitudinal support members having opposing end members perpendicular thereto at opposite ends of the longitudinal support members. The upper platform and lower platform include at least two track members intermediate the opposing longitudinal support members. The track members further include grooves extending the length thereof. A removable support member is provided that is configured to be suspendedly mounted to the track members. The support members include an upper portion and a lower portion slidably coupled.

A winch is disclosed for a pick-up bed having a floor, and a front wall. The winch includes a winch motor and spool assembled to the truck body below the floor. An upper pulley is assembled to the front wall with a cable wound around the spool that is extendable and retractable from the spool. The cable is routed over the upper pulley through an opening defined by the front wall. The opening is spaced from the floor to facilitate loading articles into and unloading articles from the truck bed.

The invention disclosed herein include system, kit and method embodiments for transportation, launch and recovery of large watercraft, particularly large unmanned underwater vehicles (UUVs). Features of the system and kit embodiments may include, but are not limited to guide rails with guide wheels mounted to the open end of a marine trailer that may be fixed or rotating between an open V-shaped position for guiding the watercraft during launch and recovery and a closed parallel position when loaded and during transportation, mounting adapter assemblies that allow the guide rails to tilt vertically to compensate for boat ramp gradient and cable guide posts for maintaining the tow cable within the open end of the trailer during launch and recovery.

A boat trailer converter. The boat trailer converter includes a trailer cage. The trailer cage includes a base and sidewalls extending vertically from the base. The trailer cage is mounted onto a boat trailer to convert the boat trailer into an all-purpose trailer.

This disclosure relates to systems and methods for aiding in the launching and/or loading of a watercraft on a mobile trailer. Various embodiments provide for an aid system that may be removably installed without significant modifications to a trailer. In some embodiments, the aid system may include one or more guide straps that are elastic, at least in part, to facilitate the guiding and positioning of a watercraft and/or associated winch hook assembly during launching and/or loading operations. Further embodiments may ease launching operations by providing a certain measure of force propelling the watercraft from the mobile trailer into the water, and/or ease loading operations by positioning the winch hook assembly towards a rear of the mobile trailer during loading operations.

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.
