World Sailing has brought the Trofeo Princesa Sofia in Mallorca, the Allianz Regatta in The Netherlands, the Semaine Olympique Francaise at Hyeres and Kieler Woche in Germany together in greater coordination of the calendar.

It claims the move will help promote Olympic-class sailing by making it easier for sailors to take part in a greater number of events.

"Each of these regattas has a remarkable heritage and provide the foundations for both the Sailing World Championships and sailing in the Olympic Games," World Sailing director of events Alastair Fox said.

The calendar for the four events has now been agreed.

Spain's Trofeo Princesa Sofia is set to begin on April 1 2023 and will be followed by the Semaine Olympic Francaise on April 29.

The Allianz Regatta is listed to begin on May 31 and the Kieler Woche at the German sailing venue from the 1972 Olympics is scheduled for June 17 June next year.

In 2024 the first three events are each scheduled to begin two days earlier in the calendar, but the Kieler Woche is set to run from June 22 to June 30, and is set to finish less than a month before the Paris 2024 Olympics begin.

"World Sailing is committed to enhancing engagement with stakeholders across sailing in the best interests of our Member National Authorities and the sailors," Fox added.

"Collaboration also creates opportunities for cross-promotion, and I know the team at World Sailing are looking forward to working with the respective event teams to develop further benefits."

Ultimately, we are looking to partner with events on all continents to work together and make sailing in the Olympic classes a better experience for sailors around the world and more accessible for our Member National Associations in every region."

The shared ambition for the long term is for all four events to be brought together under the World Cup banner, enabling a more consistent and collaborative approach which will make planning in future Olympic cycles easier, according to World Sailing.
