Rio 2016: Hannah Mills and Saskia Clark top world rankings
Hannah Mills says she and 470-class partner Saskia Clark will use their sailing world number one ranking as motivation for the Olympic Games.
Cardiff-born Mills, 27, and Clark, 36, top the rankings for the first time in the run-up to Rio 2016.
They won a silver medal at London 2012 and have already qualified for next year's Games.
"It's a super great feeling, especially this close to the Olympics," said Mills.
"With eight months to go now it's a huge motivation for us."
Mills and Colchester-born Clark have proved a successful team, claiming a gold medal at the 2012 World Championships and silver in 2015.
They also won silver at the Aquece Rio International Sailing Regatta, a test event for next summer's Games in Brazil.
Despite being ranked number one in the world in the 470-class, Mills says there will be no let up before Rio.
"We're really happy with where we are at with our training and our racing," Mills told BBC Wales Sport.
"But we obviously know there's still months to go to make some massive improvements between now and then.
"We feel confident that if we deliver our best performance we can be on top of the podium."
