Sea Emperor Reef, about a mile from Boca Raton Inlet, has a 171-foot hopper barge giving you the impression of exploring an underwater cave. The Sea Emperor was formerly a hopper barge that was donated as part of a fine levied on a dredging company that destroyed some reef habitat off Palm Beach County. It was filled with large concrete culverts and then sunk off Boca Raton. The barge is upside down with the bow pointing to the south. The barge is home to Goliath Groupers, eels, stingrays, nurse sharks, and hundreds of other fish… a photographer's paradise! The Sea Emperor is part of a 3-wreck triangle, which includes also The United Caribbean, and The Noulla Express.
