The Vessel and Her Loss
Built in 1905 for the U.S. Army Corps of Engineers as the hopper dredge Delaware, the vessel worked river and harbor projects for decades and was rebuilt in 1961 to increase capacity. Sold multiple times and renamed Hydro Atlantic by 1968, she was ultimately condemned for scrap. While under tow to a Texas scrapyard in December 1987, her old hull gave way and she sank off Boca Raton before ever reaching the breakers. She now lies deep, largely intact, and is regarded as a demanding technical dive.
