A boat including a main hull, a first pontoon hingedly connected to the main hull, and a second pontoon hingedly connected to the main hull on an opposite side of the main hull from the first pontoon. The first and second pontoons have wheels extending outwardly beyond a surface of the first and second pontoons. The first pontoon is selectively movable between a first position extending outwardly of the main hull and a second position extending below the main hull. The first wheel extends below the first pontoon when in the second position. The second pontoon is also selectively movable between a first position extending outwardly from the main hull and a second position extending below the main hull. The second wheel extends below the second pontoon when in the second position. A first strut section extends between the main hull and the first pontoon. A second strut section extends between the main hull and the second pontoon. The strut sections include deck surfaces extending across the boat. A bowsprit is hingedly connected to a forward area of the main hull and is movable between a position above the main hull to a towing position below the main hull.

A load hauling trailer assembly adapted for on and off road use includes a towable mobile chassis, a storage container body mounted on the mobile chassis and having an open top, a top cover having an outer side and being mountable on the storage container body and movable between opened and closed positions relative to the open top of the storage container body, and a carrier rack mounted on the outer side of the top cover and adapted to carry gear thereon when the top cover is mounted on the storage container body and moved to the closed position. The mobile chassis includes a frame structure, a pair of wheel subassemblies, and suspension and frame structure height adjustment subassemblies mounted to and extending transversely of the frame structure and mounting the wheel subassemblies to the frame structure.

Load hauling trailer assembly adapted for on and off road use

Apparatus and methods are disclosed for transporting watercraft with pontoons, commonly referred to as“pontoon boats.” The apparatus broadly comprises an axle assembly and a hitch assembly. The axle assembly includes beam axle, a pair of wheels mounted for rotation about the beam axle, and a pair of pads or cradles spaced apart at a distance to receive the bottom portions of the pontoons. The hitch assembly is mounted relative to the lower surface of the deck, and includes a hitch bar extending from the front end of the deck which terminates in a cup-shaped receptacle to receive the ball hitch of the tow vehicle. To tow the boat, the cradles are preferably positioned under the craft to receive the bottom portions of the pontoons just rearward of the center of gravity to achieve an acceptable tongue weight on a level surface. The hitch assembly is preferably permanently mounted relative to the lower surface of the deck through welding, mechanical fasteners, or a combination thereof. The apparatus further includes some additional fastener such as a strap associated with each cradle that extends around the outer surface of each pontoon to hold the watercraft in a towing position. To achieve a relatively narrow width during towing, the wheels are preferably mounted for rotation inside the cradles. The spacing of the cradles is also preferably adjustable to suit different watercraft having pontoons with different spacings. The spacing between the wheels may also be adjustable. To ensure transport by vehicles having a hitch ball lower that the bottom surface of the watercraft deck, the hitch bar includes a bend to position the watercraft at level attitude when the ball hitch is received by the receptacle.

Pontoon boat hauling apparatus and method

the marine vessel has a hull (1) with an axle (9) with suspension arms (11) carrying wheels (2) offset from the axle. The suspension arms have rubber shock absorbers (10). The wheels can pivot between an extended use position for towing the vessel on land and a retracted position within recesses in the hull.

Marine vessel with retractable undercarriage

Trailer wheels mounted on a boat comprising port and starboard fillings each comprising a swing mounted frame, a spring axle mounted on the frame and a wheel on the axle. The frame may be swung from a ground-running position wherein the wheel projects below the boat to a sea-going position wherein the wheel is above the bottom of the boat. Latch means are provided to releasably lock the frame in each position.

Wheel fitting for boats

A boat construction having a pair of spaced-apart slots near the stern open to the bottom of the boat and the stern wall of the boat and a retractible running gear pivotally mounted in the slots between a land transport position and a retracted position A detachable hitch having a three-point connection to the bow of the boat and a universal joint connection to a holding vehicle
