A lower deck for a watercraft is attached to and supported by an amidships hull, and an actuator slides the lower deck and amidships hull between a stowed position and an extended position on guide rails that are secured to the underside frame of the upper deck that is supported by abeam hulls. When fully extended, the lower deck remains attached to the watercraft while a portion of the lower deck's aft section and the aft end of the amidships hull remains beneath the upper deck. A pair of side beams respectively connect to a port side and a starboard side of the lower deck or the amidships hull. Sliding members, such as rollers and/or guide bars respectively connect to the guide rails, and the side beams respectively engage and slide on the sliding members.
