An improved twin hull vessel of the catamaran type, having a central bridgedeck and a pair of side hulls interconnected by lateral suspension arms. The suspension arms are pivotally connected with offset spaced connections to the bridgedeck and to each of the hulls for moving said hulls from a substantially horizontally locked position to a vertical position beneath the bridgedeck, while holding the hulls in the vertical orientation relative to the water surface, thus changing the vessel from a catamaran to a single hull vessel for moving the vessel into pier locations, or for trailering the vessel.
