The remains of the tug Charlotte ended up in shallow water in Chequamegon Bay, southwest from Port Superior in Lake Superior. The remains are just south of the Port Superior marina. According to James M. Keller, The "Unholy" Apostles, "The fishing tug Charlotte was dragged to her final resting place in 1943.". The listing for the Charlotte was dropped from the Merchant Vessels Of The United States in 1944 as being abandoned.
"Vessel (Charlotte) is badly broken up, lying in 3-6' water, and is largely sand covered; much of the hull is flattened, with the sides dis-articulated from the keel; there is no machinery present; remains consist of the bilge, sides, and bow - about 50% of the original vessel" from Archeological Site Inventory Form.
