The Swedes managed to recover during today's race after a bad start, finishing in 3rd place, but celebrating at the end, after missing the world champion title in the medal races of 2017 and 2018 World Championships.
"It was very stressful, with the offshore wind very treacherous, a lot happening on the racecourse. At first it looked like we were not doing well, but we kept trying and managed to finish first," said Fredrik Bergström.
Anton Dahlberg was "relieved and delighted happy" in what he called "an incredible week and a very tough Medal Race".
In a very disputed race and marked by poor wind conditions, the Portuguese sailors Pedro and Diogo Costa became vice-champions of the world and the Spanish Jordi Xammar and Nicolas Rodriguez managed to keep the 3rd place in final results.
In the women's fleet the Spanish Silvia Mas Depares and Patricia Cantero Reina became world champions after leading the standings for more than half of the competition.
"It was a very tense week, with many emotions every day. We were seeing that getting to the medals was complicated. They cancelled the first start, we kept trying, it was complicated, and the English's penalty at the end was incredible," revealed Silvia upon arrival.
The silver medal went to the Dutch Afrodite Zegers and Lobke Berkhout and the Italians Elena Berta and Bianca Caruso took home the bronze medal.
In the mixed competition Israel ruled the podium with Gil Cohen and Noam Homri becoming the first world champions in this class and their compatriots Tal Sade and Noa Lasry the vice champions. British Amy Seabright and James Taylor won the bronze medal.
In this competition two Olympic slots were at stake, the men's going to Portugal and the women's to Turkey.
