Form 10-900-a Wisconsin Word Processing Format (Approved 1/92) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet Advance Shipwreck (Barge) Section _7 Page 2 Town of Nasewaupee, Door County, Wisconsin extensive change from the vessel’s original 1871 app to its final app was the f of a bustle widening Advance’s hull 10 feet and changes to the vessel’s deck structure. In 1915 sister keelsons were added to the vessel to provide additional longitudinal support. This was the Advance’s final iteration and her appearance at the time of her sinking. Evidence of the bustle and keelson additions remain extant on the site. The specifics of this final configuration, as it appears as a wreck site, are described in detail below. Site Description The remains of the barge Advance lay 520 feet east of the shores of Sand Bay Peninsula, on the Green Bay side of Door County, Wisconsin (44° 51.803' N, 87° 29.817'W). The remains of the vessel rest in 8 feet of water on a heading of 50 degrees, with her bow facing outward and perpendicular to the shore. The extent of her bow and stern are missing, yet the structure just above the turn of the bilge down to the keelson assembly remains relatively intact rising 4.0 feet off the rocky bottom. The wreck’s location, in a protected harbor, has provided a sufficient habitat for wildlife and contributed to frequent visitation from fisherman and other curious visitors. The Advance shipwreck has been known to the Wisconsin Historical Society since the program’s inception. Although the vessels machinery was salvaged after the sinking and the upper deck works and hull components were broken by years of wave and ice action along the shore, major structural components of the vessel remain extant, including its keel, keelson, centerboard trunk and evidence of the bustle. In July of 2018, a survey of the Advance was conducted as a ten-day field school hosted by Society maritime archaeologists and volunteers from Wisconsin Underwater Archaeology Association (WUAA). The field school consisted of eight students from various avocational archaeology groups throughout Wisconsin, Illinois, Ohio, and Minnesota including WUAA, the Great Lakes Shipwreck Preservation Society (GLSPS), Maritime Archaeology Survey Team (MAST), and Underwater Archaeological Society of Chicago (UASC). A baseline was strung between fence posts driven at either end of the broken keelson structure, and set off a distance from the shipwreck to include all components of the site. As no stempost or sternpost is extant on site, it was not initially evident which end of the wreckage was the bow, so the baseline was stretched 136 feet along the centerline of the vessel. It was later determined by the position of the centerboard trunk that the baseline orientation was from the stern to the furthest extent forward on the bow. All measurements for the survey were taken from this baseline. The overall length of the remains of Advance is 116.3 feet. The port side of the wreck extends outward 9.0 feet with scattered debris as far as 19.0 feet. The starboard side of the wreck extends 21.0 feet with debris scattered as far as 37.0 feet. This gives an overall width of the site as 30.0 feet with debris scattered as far out as 46.0 feet. At 70 feet on the baseline, the turn of the bilge was measured 12.1 feet outward on the starboard side of the wreckage.
