The victim was sailing on the Saginaw Bay.  She was sitting on the wrong side of the vessel when it began taking on water causing it to capsize.  The victim held on to the vessel until she was pulled out of the water by the Caseville Marine Division who reached her by air boat, was wrapped in hypothermia rescue gear and transported by the Sheurer Ambulance to the Sheurer Hospital for treatment of temporary hypothermia and then released.
