A multi-hull vessel capable of planing. The vessel has a rigid superstructure that is rotatably linked to flat-bottomed hulls. As the vessel heels, the pivotable connection between the superstructure and the hulls allows the superstructure to heel over while the hulls remain oriented so that their bottoms are parallel to the water surface. This allows the multi-hull vessel to plane at relatively low speeds without risking the consequences of a leeward planar hull digging into the water. Further, the vessel is made of lightweight components and configured to be assembled and disassembled in a short time by a single individual, and to be easily lifted and carried atop an automobile for overland transport.
