PT 617, also known as Torpedo Boat PT-617, Big Red Cock and Dragon Lady, "is the sole surviving 80' Elco type PT boat and represents the USA'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 Elco type boat was the predominant type and is the same type as the famous PT-109 commanded by John F. Kennedy; the "Higgins" boat is the other type. PT-617 was declared a National Historic Landmark in 1989.
