This year's 49er world championships will be a little different to those of the recent past, not least because Peter Burling and Blair Tuke won't win.
Burling and Tuke have dominated the 49er class, winning four-straight world titles and last year's Rio Olympics. In fact, they won every major regatta after the 2012 London Olympics and won gold in Rio by a whopping 43 points.
The pair won't be in Porto for the upcoming 49er and 49erFX world championships, having recently helped Emirates Team New Zealand claim the America's Cup. They are now in preparation for the upcoming Volvo Ocean Race.
Their absence will feel strange for many, including 49erFX Olympic silver medallists Alex Maloney and Molly Meech who have been to eight world championships with Burling and Tuke.
"We will miss them," Maloney said. "They have been really good role models for us and have always been there if ever we have any questions. It will be strange not having them there but they have left us with some good knowledge."
