RedactedNarrative: WHILE DUCK HUNTING THE BOAT HAD BEEN TAKING ON A SMALL AMOUNT OF WATER.  THEY STARTED THE ENGINE AND PLACED IT IN FORWARD TO RETRIEVE DECOYS.  AT THIS POINT THE WATER IN THE BOTTOM SHIFTED TO THE STERN CAUSING THE TRANSOM TO GO UNDERWATER.  THIS CAUSED A LARGE AMOUNT OF WATER TO RUSH IN THE BOAT AND SINK.  Three people suffered from hypothermia.
