The Windjammer is the iron hull of the sailing ship Avanti, lost on Loggerhead Reef off Loggerhead Key, and the most popular dive in Dry Tortugas National Park. It lies so shallow that snorkellers and scuba divers explore it together, and the wreckage now works as an artificial reef for fish of every size.

Also known as Windjammer, Avanti, Windjammer Wreck.

The dive

The wreck runs from the surface, where a small piece of it breaks the water, down to 6 m (20 ft). The structure works as an artificial reef, gathering fish from 200-pound jewfish down to small tropical species.

The very bow and the very stern stand highest off the bottom and hold the most marine life. The ship is broken in half, so the laminated underwater map from the park visitor center helps divers find those two ends. Visibility on the site is best during the flood tide.

Built in 1875, the three-masted, iron-hulled sailing ship Avanti wrecked on Loggerhead Reef in 1901 on her way to Montevideo with a cargo of lumber. Divers know her as the Windjammer. The wreck and all historic artifacts in the park are protected by law, and the hull has since turned into an artificial reef.
