A pontoon for a catamaran includes recesses for a plurality of scuba tanks where the tanks protrude above the top surfaces of the pontoon. The exposed portions of each of an adjacent pair of tanks provide a support for a mating removable seat back. Each tank is supported by a platform at the bottom of each recess below which is a chamber which includes an air-inflatable bladder. Each bladder includes an air hose with means to connect the hose to an air supply such as a scuba tank. The air is used to expand the bladder to expel any water which may accumulate in the chamber. The pontoon not only provides increased comfort for passengers but also provides for increased seaworthiness. The structure is compatible with collapsible and self trailoring catamaran configurations.
