Lightship Nantucket

The position was 40 miles (64 km) southeast of Nantucket Island, the farthest lightship in North America, and experienced clockwise rotary tidal currents.

In addition to the obvious hazards posed by the weather and sea conditions, vessels marking shipping lanes on occasion were struck by the very traffic they existed to protect.

Lightship 11 was blown ashore in 1855 and rebuilt at the New York Navy Yard for further service at Brenton Reef, Rhode Island.

Lightship 54 was built of iron and equipped with two lanterns, a 12-inch steam chime whistle, and a hand-operated 1,000-pound (450 kg) bell fog signal.

Lightship 58 was built of an iron-plated steel frame and equipped with two lanterns, a 12-inch steam chime whistle, and a hand-operated bell fog signal.

The vessel was built on a wood-sheathed steel frame and equipped with a 12-inch steam chime whistle, and a cluster of four electric lens lanterns mounted in galleries at each mast head.

While in the Navy during World War I she continued her former peacetime routine warning shipping away from Nantucket Shoals and also aided in guarding nearby waters against German U-boats.

Lightship 106 was built on a steel hull and equipped with a 12-inch steam chime whistle, a hand-operated bell, a submarine bell,[clarification needed] a submarine oscillator,[clarification needed] a radio beacon, and a 375 mm (14.8 in) electric lens lantern at each mast head.

Lightship 117 at Nantucket was sideswiped by the SS Washington in early 1934, and four months later, on 15 May 1934, she was rammed and sunk by the British White Star ship RMS Olympic homing in on its radio beacon in dense fog.

The sunken wreck now lies hidden in 200 feet (60 m) of water 50 miles (80 km) south of Nantucket Island, Massachusetts.

[4] During World War II, Lightship 112 was withdrawn from the Nantucket Shoals station and used as an examination vessel in Portland, Maine.

In March 2000, she was purchased by William and Kristen Golden, restored as the only fully operational Lightship in the United States and converted to a luxury yacht that was berthed at Rowes Wharf in Boston.

[6][failed verification] Built at the United States Coast Guard Yard in Curtis Bay, Baltimore, Maryland in 1952.

Commissioned in September 1952 as the WAL-613 with a conventional mast, it was refit in 1953 with a "large cylindrical lantern housing installed on tripod foremast with a duplex revolving high intensity light of British design... rated at 5.5 million candlepower.
