An elevating platform attaches at the stern of a small waterplane area twin hull vessel (swath) that can be raised and lowered from a position nearly level to the vessel's deck to a position nearly level to the waterline. The platform allows convenient movement of people and equipment from the deck of the vessel to the surface of the water. Such movements may be required for either immersion in the water or removal onto another vessel or shore-side structure such as a dock. The platform attaches to the trailing edge of the vessel's struts and elevates vertically along the struts to the desired level.
