Season 4’s opening battle got underway in Chicago, with the 10-strong flying F50 fleet going head to head for glory on the waters of Lake Michigan.

SailGP’s return to Chicago set the stage for Germany’s racing debut, with new driver Erik Heil taking the wheel for the first time.

Meanwhile, Jimmy Spithill’s United States was under pressure to perform after a disappointing performance in Season 3.

However, strong winds forced the cancellation of practice day, meaning the fleet had no chance to warm up ahead of racing. It was all to play for when race day one dawned, with the F50s fighting it out across three fleet races.

It was a superb day for three-time Champions Australia, who secured two race wins and bounced back from a disastrous start in the second fleet race at the back of the fleet to finish fifth.

Erik Heil’s Germany had a solid racing debut, competing with the mid-fleet and even placing as high as 4th during the first fleet race.

But it was a disappointing day for Jimmy Spithill’s home team, which finished the day behind Germany with 9-10-6 results.
