Ambrose Lightship was a common site for smugglers during Prohibition. The Lightship marked the entrance to Ambrose Channel. That channel is in New York’s Lower Bay before the Narrows which connects to the Upper Bay.
The lightship is located now at a dock in Manhattan on the lower East River. People can visit it at the South Street Seaport Museum.
If this lightship could talk, it would tell tales of liquor smuggling when it was in active service. Once a Canadian captain stopped his ship near the lightship around midnight to unload liquor onto a local barge. The Coast Guard patrolling the area happened upon the unloading. During the gunfire, the captain was hit. He was rushed to the Marine Hospital on nearby Staten Island where he died. Conscious to the end, he refused to say anything helpful to the authorities.
Other approaches to Manhattan
A few smugglers approached Manhattan from Long Island Sound and Hell Gate or through waterways to the west of Staten Island. But the vast majority sailed, steamed, or motored past Ambrose Lightship. Usually in the dark of night.
