While attempting to cross the lake in choppy conditions, the operator attempted to get on plane.  At this point an inner-tube blew out of the vessel.  The operator turned around to retrieve the inner tube, and because of the choppy conditions and the bilge pump on the vessel not working, a large wake entered the rear of the vessel causing the vessel to swamp.  The operator headed for the nearest shore and the vessel eventually capsized.
No injuries reported.
Report filed by operator.
