Abstract: A trailer for launching a boat and a personal watercraft includes a chassis. An elevated platform attached to the chassis supports a personal watercraft above the chassis. A boom assembly pivots relative to the chassis between stored and launch positions. The boom assembly also has an intermediate position above the watercraft. A boom winch controls pivoting of the boom assembly. A watercraft winch on the boom assembly has a cable extending to the watercraft. When the boom assembly is in its intermediate position, the watercraft winch raises the watercraft off the elevated platform. Then the boom winch pivots the boom assembly to the launch position in which the watercraft is in the water. The cables then are released from the watercraft. Thereafter the boat is launched conventionally from the trailer.

Abstract: A system for docking a boat under substantial power in calm or rough seas includes a modified trailer platform having goalposts that guide the boat onto the platform. An elastic harness is attached to either side of the trailer platform and is positioned to interface the V-shaped bow of the vessel. A latch on the bow snags the harness as the vessel is being docked.

The moving device includes a lifting arm mounted on a pivot pin at one end on the frame and pivotally connected at another end to the cradle. A hydraulic cylinder and piston are mounted on the frame and connected to the lifting arm. A track, mounted on the frame, has a ramp part on the side of the frame opposite the pivot pin, and a linear section tending slightly upwardly in a direction towards the pivot pin. An arm on the cradle has, at its outer end, a wheel that runs in the track and moves in a direction toward the pivot in response to the raising of the cradle by the lifting arm.

Abstract: A self-loading and unloading trailer which can be operated by a single person to load a boat from difficult boat ramps or even directly from the ground provides rollers for engaging a boat. A first set of rollers engages the boat at ground level, enabling the boat to be winched directly from the ground or from a shallow landing. As the boat is loaded, the rollers shift and transfer the load directly to a second set of rollers. Finally, the boat weight shifts the trailer again, causing the rollers to retract, thereby bringing the boat to safely rest on bunks for storage or during transit. In the preferred embodiment, the boat is a pontoon boat, though other appropriate boat hulls are contemplated for use with the present invention.

Abstract: The present invention is a boat guiding means comprising two boat guiding mechanisms that are attachable near the rear of each side of a standard boat trailer. When the trailer is backed down a boat ramp into the water (with or without the boat), buoyant guiding arms on the guiding mechanisms pivot upward so the guiding arms remain approximately parallel to and near the surface of the water when the trailer has been submerged to an appropriate depth for loading or unloading a boat. The guiding arms thus provide a guiding surface near the rear of both sides of the trailer to prevent the stem of the boat from wandering during loading or unloading of the boat from the trailer.
