ABSTRACT:
A flotation platform is set forth comprising a first chamber of a first width underlying a superimposed upper chamber of a second width substantially twice the width of the lower chamber to enable selective inflation of the upper chamber to accommodate and effect comfort to a user while enabling inflation of the lower chamber to an elevated pressure to maintain stability of the platform. The platform further includes a perimeter cord integrally secured at the junction of the upper and lower chambers and positioned within an arcuate recess coextensive with the cord wherein the cord is of a cross-sectional area greater than the wall thickness of either lower or upper chamber. The cord anchors a series of forward handles at a forward wall of the platform and a series of lower handles at a lower series of platform to rigidly secure the handles to the cord and the platform. Each handle is provided with a spring-biased clip to enable a user to rapidly secure a tether line to the clip in lieu of the handle. The handles and clips enable the rafts to be tethered to one another or to docks and the like for ease of use and safety and securement.
