Spanish Galleons by Caribbean Catamaran Charters Florida is famous for its fabled Spanish treasure galleons. Florida's coastline is dotted with more colonial Spanish wrecks than any other state in the nation, primarily because of three treasure fleet disasters. In 1622, 1715, and again in 1733, Spain suffered horrible economic blows when the treasure fleets or flotas entered Florida waters and were destroyed by hurricanes. The 1622 fleet was scattered across the lower Florida Keys and the Dry Tortugas.
