Abstract
Abstract Disclosed is a trailer for simultaneously carrying a wheeled motor vehicle and a boat. The trailer uses vehicle ramps mounted forward of the trailer wheels to provide a platform upon which the motor vehicle is carried. An inclined hull supporting structure is mounted at the rear portion of the trailer so that the boat can be carried with the bow positioned above the motor vehicle. The trailer has a frame which is slidably adjustable upon a wheel carriage to allow shifting the load for varying load conditions. The trailer is constructed to allow loading and launching of the boat independent of whether a motor vehicle is thereon.
