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. When used with boats and vehicles of normal sizes and weights the trailer automatically maintains the center of gravity of the trailer within an acceptable range whether used in the single load or dual load modes of operation, and without adjustment.
