The Lifesaving Museum preserves the memory of those islanders who risked their lives to save shipwrecked mariners. The building is a replica of Nantucket’s Life-saving station. Inside is an interesting display of objects on the topic including historic photos and actual surfboats from the Massachusetts Humane Society, the predecessor of the Coast Guard. The collection includes film footage of the sinking of the Andrea Doria, which took place off the coast of Nantucket in 1956. Kids will like the exhibit on Coast Guard sea dogs. The museum is about 3 miles from town and is a nice stop by bike for those riding the path to Surfside Beach.
