Site details

Lightship LV-71 marked the deadly Diamond Shoals for over 20 years before being shelled and sunk by U-140 on 6 August 1918 — the only U.S. lightship ever lost to enemy action; her entire crew survived. The 122-ft vessel now rests in 180-200 ft of water just off the shoals and was listed on the National Register of Historic Places in 2015. The depth, current and remoteness make this strictly a technical (trimix) dive visited only occasionally by expedition-level divers.
