"Inside my empty bottle I was constructing a lighthouse while all the others were making ships." Why not in a second empty bottle a
lightship??
The Nantucket at Boston the LV-112 was the replacement lightship for the Nantucket that was struck and sunk in 1934 by the RMS Olympic (sister ship of the Titanic). The LV-112 was the largest U.S. lightship, one of eleven that served on the Nantucket Shoals and for 39 years, the longest serving at this station. The Nantucket at Newport is the LV-612 that replaced the LV-112 in 1975.
From 1979 to 1983 the LV-613 (formerly Ambrose) became Nantucket II and alternated duty at Nantucket Shoals with LV-612. This was the last U.S. lightship station and that came to an end on December 20, 1983 when the lightships at this station were replaced by a Large Navigational Buoy.
This site below contains an account of the good and not so good life aboard a lightship written by CHBOSN James B. Gill, USCG ret, Commanding Officer of the LV-612 from 1960-63.
