The schooner Libbie Nau was raised from the Island Mill dock slip (she sunk there in 1919) and towed to the Leathem & Smith shipyard to be used as a breakwater for their dock. The vessel was filled with stone and sunk on the south side near the steamer Holland which was serving the same purpose. They burned to the water's edge on 9/17/1922. When the Door County Produce Co. warehouse burned, the fire spread to the dock and the remains of the Libbie Nau burned to the waterline.
