A ship that was headed out from the Sturgeon Bay canal Tuesday morning was towed back to Bay Shipbuilding after a fire broke out on the bow.  The Burns Harbor, a 1000-foot freighter that was built in 1980 at Bay Shipbuilding, returned to the yard’s docks about 12:30 Tuesday afternoon after the Sturgeon Bay Fire Department and the United States Coast Guard assisted the ship’s crew in putting out the fire.  The U.S. Coast Guard only provided assistance and could not give any further details.  Bay Shipbuilding President Todd Thayse said he could not comment immediately and the Sturgeon Bay Fire Department could not be reached as of late Tuesday.  DoorCountyDailyNews.com will update this story as more information becomes available.
