Patent attributes
An extendable and retractable lower deck is supported by one or more longitudinally extending hulls. The lower deck slides between an extended position and a stowed position on rails that are secured to the underside of an upper deck of a houseboat, pontoon boat, tritoon boat, catamaran, floating dock, pier-supported dock or other watercraft or dock. When fully extended, the floating deck remains attached to the watercraft, and additional width may be achieved with laterally expandable panels in the lower deck. Various accessories are connected to the lower deck or to a storage hold in the hull beneath the lower deck, such as a pool liner insert, a hot tub liner insert, a slide and ladder assembly, a seat and mounting bracket assembly, a volleyball net and pole assembly, an umbrella and pole assembly, a hammock and stand assembly, a seat lift, and an expandable deck insert.
