ABSTRACT:
A ramp assembly for a pontoon boat, or the like, on which a boat user can come and go from the pontoon boat without having to get wet. A cylindrical float, rotatably attached to the free end of the ramp, keeps it and at least one user thereon afloat. Moreover, the float acts like a roller during docking, enabling one to move the ramp, in its extended position, up and onto the shore at most beaches. The ramp assembly comprises a support structure attached to the underside of the boat and a ramp including a platform which is slideably connected to the support structure by a shaft. Bearing blocks suspend the shaft and the platform, which is pivotally connected thereto, horizontally between a pair of rails. Riding on elongated bearing surface tracks mounted within the rails, the bearing blocks allow the platform to be easily extended outwardly from the support structure for use or, alternately, retracted into it for storage. The platform can be readily extended or retracted, as needed, manually. A motorized embodiment for control of the platform is also provided.
