An apparatus and method for providing a self-activating stop device at the back of a hauling trailer for a boat. The apparatus is a compact, lightweight and durable U-shaped housing having a retractable stop element pivotably positioned therein. Through-holes in the housing permit the apparatus to be quickly and easily secured to bunkers or other framing at the trailer back end. The U-shaped housing's top surface can be easily aligned with the top surface of the bunk or framing while the stop element is biased in an upright position. When the boat is lifted out of the water and slid onto the bunker or framing, the boat's presence pivots the stop element down into the housing and once the transom of the boat passes over the stop element, the stop element self-activates, pivoting upward acting as a stop against the transom, thereby preventing the boat from sliding back off of the trailer.

A lateral brace for stabilizing a bunk on a boat trailer. The brace includes an anchor bracket attached to 3 rigid portion of the trailer and a bunk bracket attached to a bunk or to a bracket connecting the bunk to the trailer. An adjustable link connects the anchor bracket to the bunk bracket. The length of the adjustable link can be varied in order to place a desired lateral force on the bunk. This lateral force counteracts the splaying force applied by a boat hull resting on the bunk.

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 cart for transporting an aquatic vessel is provided which includes an axle, at least two wheels arranged on the axle, a frame having support posts extending from the frame to support the aquatic vessel, at least two elongated ties secured to the frame or the support posts, each having a wheel chock arranged thereon configured to be removably placed adjacent to one of the at least two wheels to stabilize the cart at rest, and a kickstand. The cart and its components can be disassembled in a variety of different configurations to allow the cart to be stored in a number of different configurations, including inside of the aquatic vessel, when the cart is not in use.

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.

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.

A trailer mounted protection device (10) for protecting a vehicle (20) positioned on the trailer (18) from debris, the device including a first frame-enclosed panel (13A) and a second frame-enclosed panel (13B), each panel connected to the trailer (18), a first connecting assembly (40, 49A, 49B) for connecting a leading side (26A, 26B) of the frame (12A, 12B) of each panel (13A, 13B) to a forward part of the trailer (18), a second connecting assembly (71) for connecting a trailing side (28A, 28B) of the frame (12A, 12B) of each panel (13A, 13B) to a rearward part of the trailer (18), wherein at least one of the connecting assemblies is adjustable to enable connection of the device (10) to differently sized or differently shaped trailers.

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 tether line is mounted in a retriever and, when a water vessel is launched into the water, the retriever applies a tension force to the tether line. After the water vessel is launched, the tension on the tether line pulls the water vessel from its launched floating position towards the stationary object. The retriever is rotatably mounted on the water vessel or the stationary object such that it will pivot around a vertical axis and point in a direction towards and along the tether line. A spool mounted on the structural unit holds the tether line, and an electrical or mechanical motor, such as a spring B-motor, places a torque on the spool and a tension on the tether line. After the water vessel is launched, the tension force from the motor pulls the water vessel from a launched position to the stationary object. A self-governing control mechanism in the retriever senses at least one operating parameter of the retriever and limits the retrieval of the tether line to within predetermined operating conditions. The self-governing control mechanism may sense the tension on the tether line and stop retrieval of the tether line when the tension on the tether line drops below a predetermined tension. The self-governing control mechanism may also (or alternatively) sense the speed of the spool and apply a brake force proportional to the spool's rotational speed.

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.
