The boat-trailer launch and recovery device has a right rail and a left rail, which rails are attached to a trailer post by holding plates. The right rail and the left rail each have a bend section. A spring loaded gate is attached to either the right rail or the left rail. A stop bar connects the right rail and the left rail between the spring loaded gate and the trailer post. Attached to the bow of work piece boat is a removable bow post, which bow post has a socket, an inner core pipe section, and an outher PVC sleeve which freely rotates around the inner core pipe section. The outer PVC sleeve is held in place with a collar and a collar set screw with a cap at top. The right rail and the left rail each have one or more trailer post adjustment holes and one or more gate adjustment holes. The trailer post holding plates have four or more bolt holes to adjust the height of the rails.
