Chris took this photo in Connecticut on Saturday, and sent it over with an email which said drily "I have some reason to believe this might be the Nantucket Lightship."
Coast Guard Lightships marked the dangerous Nantucket Shoals since 1854. The Shoals are located on the heavily-trafficked transatlantic route to New York, 50 miles off the Nantucket coast. This lightship, "Nantucket 2," was decommisioned in 1983.
She has been refurbished as an elegant charter and events ship. The photos of the interior would surely not be recognizable to the guys who manned her.
You can tour the Ambrose Lightship, familiar to all sea travellers due to its old ocean station outside New York Harbor, in its original condition at New York's South Street Seaport.
