There is also provided a method for the use of the craft in game play and the use of the same in a manner which allows the power source for the drive to be managed. A system for transport, charging and/or communication with the craft from onshore is also provided, along with a system to allow the use of the craft within a specified area on the body of water to be maintained and controlled.

A trailer for transporting a vehicle may include a supporting structure adapted to carry the vehicle. A bracket structure including a tail light assembly may be attached to a section of the supporting structure. The tail light assembly may include tail lights for the trailer. The bracket structure may be movable between a first position in which the tail lights are positioned at the rear of the trailer in a driving position, and a second position in which the tail lights are positioned away from the rear of the trailer in a loading position. The bracket structure may be adapted to fixate the vehicle to the supporting structure when placed in the first position. A method may also be provided for placing a vehicle for transport on a trailer.

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 trailering support device able to facilitate loading of a hull onto a trailer includes one or more controllers configured or programmed to perform an automatic vessel steering control to move the hull toward the trailer; estimate, based on a content of the automatic vessel steering control, a position and an azimuth of the hull at a predetermined time after a start of the automatic vessel steering control; detect the position, a steering angle, and the azimuth of the hull; compare the estimated position and azimuth, respectively, with the position and the azimuth detected at the predetermined time; and determine, based on a comparison result, whether the loading of the hull onto the trailer able to be performed; and in a case where it is determined that the loading of the hull onto the trailer is not able to be performed, provide notification of the determination that the loading of the trailer is not able to be performed.

A vehicle operational diagnostics and condition response system includes at least an axle supporting a cargo transport unit frame, a suspension disposed between and secured to each the cargo transport unit frame and the axle, a load detection device interacting with the suspension and communicating with a system controller, wherein the system controller is supported by the cargo transport unit frame, and a cargo transport unit health status system supported by the cargo transport unit and configured to communicate with the system controller. The cargo transport unit health status system provides state status information for monitored operational elements of the cargo transport unit.

A boat trailer axle rinsing system including a pipe assembly and a tank assembly is disclosed herein. The pipe assembly includes a flush pipe and a nozzle pipe, the nozzle pipe is connected to the flush pipe by a valve, the nozzle pipe includes a plurality of nozzles to rinse an underside of a boat. The tank assembly includes a tank and a dial. The tank stores a desalination chemical. The dial controls the ratio of dilution of the desalination chemical with water provided to the tank by a water hose or by a pump. The tank has an output having a manifold connected therein. The manifold is connected to the flush pipe to provide the desalination chemical to the nozzle pipe to rinse a boat. The pipe assembly is mounted to a trailer axle. The tank assembly is mounted to a front portion of the trailer axle.

Methods and systems for monitoring a load in a trailer coupled to a vehicle. One method includes determining, with an electronic processor, an initial weight on a rear axle of the vehicle when the load is engaged with the trailer coupled to the vehicle. The method also includes monitoring, with the electronic processor, a current weight on the rear axle of the vehicle based on data collected by a sensor. The method also includes comparing, with the electronic processor, the initial weight and the current weight. The method also includes automatically generating, with the electronic processor, a notification when the current weight is different than the initial weight by a predetermined threshold.

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 boat guide is coupled with a boat support and includes one or more float assemblies. The float assemblies are coupled with the boat support such that forward and rearward ends of the float assemblies are movable between lower and upper positions with respect to the boat support. The float assemblies are independently moveable with respect to the boat support. One or more boat guides may be positioned at the entrance of the boat support to help orient the vessel as it enters the boat support. A boat stop may be positioned at the end of the boat support to position the vessel along a length of the boat support. The boat guide is easily adapted for use with docks, slips, boat lifts, and trailers.

A boat trailer stair system is provided for facilitating access to a boat supported by a trailer. The system includes an A-frame configured stairway having interconnected forward and rearward frame sections that angularly diverge from top to bottom for positioning adjacent to a vessel supported on the boat trailer. The upper ends of the frame sections are interconnected and the diverging lower ends are fastened to longitudinally spaced apart locations on a longitudinal beam of the boat trailer. At least one of the frame sections supports a plurality of steps that ascend the frame section adjacent to the hull of a supported vessel. A pair of interconnected stairways may be mounted to the trailer on respective sides of the supported boat.
