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 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.

A boat trailer and a method of backing up a boat on a trailer. The boat trailer includes a trailer back-up system having a first image capture device, a second image capture device, and a transmitter. The first image capture device is mounted on a left guide pole of the trailer in a rear-facing direction, and the second image capture device is mounted on a right guide pole of the trailer in a rear-facing direction. The transmitter is in communication with each of the first image capture device and the second image capture device and configured to transmit live video images from the first image capture device and from the second image capture device to a display device. The method includes moving the trailer with a boat loaded on the trailer in a rearward direction and capturing, in real-time, a first view and a second view.

Pontoon forks are specifically designed for the marine industry to efficiently and safely lift and maneuver pontoon boats. The pontoon forks are engineered to lift tri-toons and pontoon boats of lengths up to and greater than twenty-eight feet. The forks can further accommodate weights of up to and greater than six-thousand pounds. Removable pockets included with the pontoon forks allow for the lifting and transport of pontoon boats of various sizes without having to have specialized equipment for each and every make and model of the pontoon boat. The pontoon forks are retrofit to fit specific forklifts already owned or easily acquired by marinas.

A buoyancy tank for a portable floatation apparatus which allows for the elevation of a watercraft above a water-line and which allows for the removal of the watercraft from a body of water. The buoyancy tank has at least one and/or a plurality of integrated cylindrical structures which supports the floatation apparatus in transport and storage. The integrated cylindrical structures provide sufficient support to allow the removal of the floatation apparatus by use of a boat lift and further provide sufficient support to allow a watercraft to be stacked on top of the floating apparatus while the floating apparatus is stacked on top of the floating apparatus for the purposes of storage. A plurality of said buoyancy tanks may be connected to the portable floatation apparatus by use of connecting means. The portable floatation apparatus should have a pumping device which pumps a sufficient volume of air into a plurality of the buoyancy tank which is effective to selectively and conveniently elevate a watercraft above a water line.

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 engageable actuator configured to selectively latch or release the trailer connector from the boat trailer.

The invention relates to a trailer that is especially used for moving over very soft ground and for launching lightweight boats, comprising a motor-driven supporting running gear (11) designed to hold the hull of the boat and extended by a longitudinal edge (12) ending in a lift jack (13) comprising a maneuvering handle (132). The supporting running gear (11) comprises an essentially tubular frame (111) arranged transversely to the longitudinal axis of the trailer, and to which a sealed differential-motor reducer unit (14) or an electric motor could be fixed.

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.
