An inflatable water craft for underwater observation, the craft incorporating an integral underwater viewing window which includes a top and bottom transparent lens sonic welded to the craft intermediate a cavity which passes through the top and bottom of the craft forming a viewing port. Inflatable stand-offs protect the bottom lens. The top and bottom lenses includes a closeable vent. An inflatable pillow is sonic welded proximal the top transparent lens. Inflatable boarding guides center the user on the craft and air chambers support the user's body weight thereby preventing sagging or bending of the craft. The craft may further comprise a hand-held device for wading and swimming activities. Use of sonic welding and specific materials prevents undesired leakage into viewing port and prevents discoloration of the top and bottom lenses.
