ABSTRACT:
A floatable water board for supporting at least an upper body portion of a user person lying on the board when in a body of water is described. The board is formed of a flotation body constructed of buoyant material. The flotation body defines a bow end portion, a stern end portion, a top surface, and a bottom surface. A viewing cavity is provided in the flotation body and disposed at a predetermined location in a forward region of the flotation body. A transparent pane is sealingly retained at a bottom end of the viewing cavity and extends substantially in a plane of the bottom surface. An inflatable circumferential flotation collar assembly is secured about the cavity by a flexible and extendible section sealingly engaged about the viewing cavity and deployable above the top surface of the flotation body. The bottom surface of the flotation body is also provided with rails and channels to direct a water flow over the pane to evacuate any air bubbles which can impair visibility.
