Single-day sailing competitions

The Barcolana () is a historic international sailing regatta organized by the Sailing Club of Barcola and Grignano (Società Velica di Barcola e Grignano). It takes place every year in the Gulf of Trieste on the second Sunday of October. The Barcolana is one of the most crowded regattas in the world. The Barcolana became the Guinness World Record holder in February 2019 when it was named "the greatest sailing race" with its 2,689 boats and over 16,000 sailors on the starting line.
