Abstract: A trailer capable of carrying a boat and vehicle in a dual load mode of operation wherein the boat is mounted rearwardly of the vehicle in an inclined position with the bow of the boat above portions of the vehicle being carried. The trailer is also convertible into a single load mode of operation wherein the boat is carried low in a conventional orientation by lowering a supporting boat carriage into a collapsed position near the frame of the trailer. The trailer is provided with a boat carriage which is connected to the frame of the trailer and supported by a lifting mechanism which causes the boat carriage and any supported boat to shift rearwardly when they are moved from the collapsed position into the extended raised position. This rearward movement automatically shifts the weight of the boat carriage and any supported boat rearwardly to counteract the loading associated with a vehicle on forward portions of the trailer.

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.
