The present invention describes improvements to an air-floated apparatus having a deck with an open bottom, a platform enclosing a portion of the open bottom of the deck to define a pressure chamber, and an impeller for pressurizing air in the pressure chamber to float the housing above a support surface, the platform having an opening and the deck having an outer periphery. According to the invention, a novel structural member is supported between the deck and the platform along a predetermined portion of the deck outer periphery, the structural member including an upper wall and a lower wall defining a chamber.
