Excerpted from Huffington Post:
Nearly 80 years after it began safeguarding trans-Atlantic shipping lanes with its powerful light, radio beacon and foghorn, Nantucket Lightship/LV-112 will once again be illuminated in its homeport of Boston. The "Statue of Liberty of the Sea," as it's affectionately known, is a symbol of America's development. Anchored 100 miles off the U.S. mainland near the dangerous Nantucket Shoals from 1936-75, it was the last landmark seen by vessels departing the United States and the first beacon seen by many immigrants entering U.S. waters. Designated a National Treasure by the National Trust for Historic Preservation in 2012, the lightship will receive a $250,000 grant from American Express to rebuild its navigational light beacon, foghorn and on-board electrical systems.
