In association with Irish Sailing
The sailing event will be held in the remote coastal resort of Marseille, over 700 km from the main Olympic Games venue in Paris.
A mixed two-person offshore keelboat will join kiteboarding, windsurfing, multihulls, singlehanded and doublehanded dinghies and skiffs.
Three of the 10 events to be contested in Tokyo in 2021 will be replaced for the following Olympics in a drive for gender equity in the sport.
The new medal events to be introduced are a mixed one-person dinghy, a team event where men and women compete in separate gender-specific boats, a mixed two-person dinghy and mixed kitesurfing - making a first appearance for kitesurfing at the Games after it was adopted and then dropped for Rio 2016.
