An objective of the present invention is to provide users with a kayak transporting apparatus to assist the users in the transportation of a kayak with minimum effort and strain to the users' body. The present invention provides a kayak carrier for a vehicle that can be adjusted to fit various sizes and shapes of kayak. The present invention is a low-profile apparatus compared to other kayak transporting apparatuses. The kayak transporting apparatus is also intended to be easily stored away as the kayak transporting apparatus is light-weight and the components of the apparatus are detachable from each other. Further, the present invention is a hitch attachment for the rear of a vehicle which facilitates the backing of a vehicle compared to a trailer ball attachment of other kayak transporting apparatuses. Thus, the present invention is a light weight, compact, versatile apparatus for transporting kayaks efficiently.

A trailer pontoon bottom has built in wheels designed to fold under the trailer pontoon to be clear of the water and to extend out and lock for land use and be clear of the pontoons. A pair of swing arms each having a first end attached to an inside axial hub of the wheel are designed to rotate on a boss of the first end. A second end of the swing arm is configured to rotate a maximum of 90 degrees from its folded position into a trailer position. An axis parallel to a back end of the trailer pontoon is configured to attach to each of the pair of swing arms at a respective pivot located a swing arm distance from an edge of the trailer pontoon. The axis is rotatable by less than 90 degrees to enable each wheel to retract against a suspension bumper.

A transporting device for launching and hauling boats is provided. The device includes a frame arranged to support a boat hull and is provided with at least two pairs of wheels. Each pair of wheels is formed by two wheels aligned with each other on opposite sides of the frame, and the frame is further provided with one or more tracks. The device is capable of easily and effectively moving both on roads and other hard terrains, and on soft terrains, such as for instance sandy or muddy terrains. According to an embodiment, the wheels and the tracks are mounted on the frame so as to be movable in a direction perpendicular to the plane of the frame itself so that they can be selectively brought into contact with the underlying ground or moved away from ground depending on the kind of terrain on which the device is moving.

A drive unit of a robotic vehicle including a top surface having a mounting interface to interchangeably couple with multiple different modular payload structures configured to transport items in a facility, workspace or inventory management environment. The mounting interface is configured to securely engage with a mounting portion of the variety of different payload structures to enable a versatile exchange of the payload structure for different conveyance applications. The drive unit includes an electrical interface to communicatively couple with the modular payload structures. The drive unit is configured to use data communicated via the electrical coupling and interface to identify a type of modular payload structure that is mechanically coupled to the mounting interface and implement a motion profile (e.g., speed and acceleration parameters) associated with the identified modular payload structure.

Vehicle securing apparatuses may include a main support arm. A base arm may be carried by the main support arm. A retainer assembly arm may be carried by the main support arm in spaced-apart relationship to the base arm. A retainer space may be defined by and between the base arm and the retainer assembly arm. A retainer assembly may include at least one retainer hasp pivotally carried by the retainer assembly arm. Accordingly, a structural member on an ATV, lawnmower, watercraft or other vehicle may be extended into the retainer space as the structural member pushes the retainer hasp from a retaining position to a release position. The retainer hasp may return to the retaining position to retain the structural member in the retainer space as the structural member clears or passes beyond the retainer hasp.

A hitch assembly includes a support extendable into a receiver tube attached to a vehicle. A sleeve has a top end and a bottom end. A bracket is attached to the sleeve and is attached to the support to vertically orientate the sleeve. A piston is positioned in the sleeve and extends outwardly of the bottom end. The piston has a lower end that is moveable toward or away from the bottom end. An actuator is mounted on the sleeve and is mechanically coupled to the piston. The actuator is actuated in a first direction to lower the lower end and actuated in a second direction to raise the lower end. A ball mount is removably attached to the piston adjacent to the lower end. A hitch ball is attached to the ball mount and engages a hitch coupler of a trailer.

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.

Methods and apparatus are disclosed herein that determine a vehicle backup position for launching and loading a boat using trailer hitch load. An example apparatus includes a data analyzer to determine, based on a trailer hitch load of a vehicle coupled to a trailer, a vehicle backup position for launching the boat at which a boat coupled to the trailer is floating on a body of water and an instruction generator to instruct a braking system of the vehicle to stop the vehicle at the vehicle backup position for launching the boat.

A trailer pontoon bottom has built in wheels designed to fold under the trailer pontoon to be clear of the water and to extend out and lock for land use and be clear of the pontoons. A pair of swing arms each having a first end attached to an inside axial hub of the wheel are designed to rotate on a boss of the first end. A second end of the swing arm is configured to rotate a maximum of 90 degrees from its folded position into a trailer position. An axis parallel to a back end of the trailer pontoon is configured to attach to each of the pair of swing arms at a respective pivot located a swing arm distance from an edge of the trailer pontoon. The axis is rotatable by less than 90 degrees to enable each wheel to retract against a suspension bumper.

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.
