Motor torpedo boat PT-617, also known as Big Red Cock and Dragon Lady, "is the sole surviving 80' Elco type PT boat and represents the United States's most heavily used, highly favored, and combat-tested PT boat type in World War II." She is a museum ship at the PT Boat Museum in Fall River, Massachusetts. The 80-foot (24 m) Elco type boat was the predominant type and is the same type as the famous PT-109 commanded by John F. Kennedy; the 78-foot (24 m) "Higgins" boat is the other type.
