An 80-foot Maryland Department of Natural Resources icebreaker fought through up to twelve inches of ice on Monday to free watermen who had been stuck in Rock Hall Harbor for more than two weeks. ABC 7 News reports the icebreaker, A.V. Sandusky, was dispatched to the Eastern Shore town after frigid temperatures locked in dozens of boats and brought the local commercial fishing industry to a standstill. Once the harbor was cleared, the Sandusky planned to head south toward Kent Narrows, where another group of watermen had been unable to reach open water.
