For centuries, sailors from all over the world have been attracted to the Azores mainly because of the international relevance of the Marina of Horta. All the islands of the archipelago have quays and harbors. The islands of São Miguel, Terceira and Faial have harbour centres with equipment for repairs and other facilities for boats and crews. Together, all the marinas, which have been awarded the blue flag, offer more than 1,000 mooring berths. Many international regattas start, pass or end here.
