The Yacht Club Costa Smeralda, founded in 1967 by its President H.H. the Aga Khan, is renowned for organising international sailing regattas for superyachts, maxi yachts and one-design yachts.

The Yacht Club runs regattas during the summer season and offers exclusive services to its members, their guests and yacht owners in Porto Cervo.
The Yacht Club Costa Smeralda has promoted international challenges such as Azzurra - the first Italian challenger for the America's Cup in 1983 - which became an Italian sporting icon.

In 1992 the Club launched the motor yacht Destriero, which to this day holds the transatlantic crossing record set in the same year.
In 2017 the YCCS celebrated the 50th anniversary of its foundation, an important milestone which was marked with the launch of an environmental project aimed at promoting the safeguard of marine environments and from which the One Ocean Foundation was born.
