A wheeled boat trailer of the type used to tow a boat to a body of water is provided with a walkway leading to a dock ramp hingedly coupled to the rear end of the trailer for rearward extension into the body of water after the boat has been launched. Downwardly extendable support legs are mounted to the end of the dock ramp furthest from the trailer to support the dock ramp above the water surface. A pulley mounted atop a mast removably secured to the trailer near the rear portion thereof allows a conventional front-mounted trailer winch to elevate the dock ramp while the trailer is backed into or pulled from the water. When not in use, the dock ramp may be pivoted about its hinged coupling to a stowed position extending forwardly across the trailer. The dock ramp may be positioned along the longitudinal axis of the trailer, and the underside of the dock ramp may incorporate rollers for engaging and supporting the keel of the boat when the dock ramp is in the stowed position. One or more dock ramp extensions may be coupled to and extend from the dock ramp for increasing the effective length of the portable dock.
