United States lightship Nantucket

The United States Lightship Nantucket is a lightvessel in Boston Harbor serving as a floating museum. Its steel hull with red sides and white superstructure displays the working layout and equipment of a ship that once guided vessels safely through busy waters.

Built in 1936, this vessel served as a navigation aid until 1983, replacing an earlier lightship that had been damaged in a collision. It played a crucial role in guiding maritime traffic safely for nearly half a century.

The vessel marked the arrival of thousands of immigrants coming by ship to America, serving as a symbol of hope during their journey across the ocean. It connects visitors today to the stories of those who started their new lives here.

The vessel is moored in Boston Harbor and easily accessible by public transportation. You can walk aboard to explore the interior spaces, navigation equipment, and crew areas that show how people lived and worked on the ship.

This is the largest lightship ever built in the United States, giving it advantages in rough weather and allowing longer periods on duty in open waters. Its size made it more stable and reliable than smaller versions that served elsewhere.
