"Founded in 1970 as the Manitowoc Submarine Memorial Association, the Wisconsin Maritime Museum has grown into one of the largest maritime museums in the Midwest. In addition to commemorating the maritime heritage of the Manitowoc-Two Rivers area and the submarines built here during World War II, the Wisconsin Maritime Museum is now a leader in preserving the maritime history of Wisconsin and the Great Lakes region. Museum includes the USS Cobia, a WWII submarine that can be toured and, as part of group evens, be used for a sleepover (I'm talking to you Cub Scouts!)."
