Abstract: A heated personal boating blanket having a wind and water resistant nylon covering and woven fleece lining for delivering thermally controlled air to a occupants in a boat. The nylon covering and fleece lining are connected at the periphery forming an inflatable chamber into which a heated air supply hose from the boat heater is inserted to supply heated air to the inflatable chamber. The heated air is dissipated from the inflatable chamber through the fleece lining directly onto the occupants draped in the heated personal boating blanket. Utilizing the existing flexible boat heater hose as a source of heat there is no need for bulky external heating apparatus. Utilizing the existing flexible boat heater hose eliminates the possibility of electrical shock from internally electrically heated blankets. The heated personal boating blanket does not attach to boat occupants in any way thus avoiding possible entanglement of the boat occupants in emergency situations and upsets.
