Abstract: This application covers a trailer which has platforms at two levels, one for a boat and one for an automobile. It includes a frame supported by wheels, a primary loading platform which rests on the main frame and is pivotally attached thereto so that it can be tilted therewith. An upper or secondary load carrying platform is supported above the primary load platform by four stanchion. Means are provided to pull the secondary load platform down to the first load platform and then pivot the two so that a boat can be pulled onto the upper or secondary load platform. Then, the upper load platform is pivoted about the stanchion to an upright position and locked in place. The secondary or primary loading platforms are then pivoted together and the lower platform can then be loaded, for example, by driving a car up on it. When it is loaded, then the fixed primary and secondary loading platforms are rotated about the pivot so that they rest securely on the main frame.
