Rio Olympics 2016: Sir Ben Ainslie tips Giles Scott for Finn class dominance

Four-time Olympic gold medallist Sir Ben Ainslie says fellow sailor Giles Scott can dominate the sport's Finn class for as long as he wants to.

Scott will be crowned Olympic champion and Great Britain's fifth successive winner on Tuesday after the medal race.

Weymouth-based Scott, 29, will become part of Ainslie's BAR Land Rover America's Cup team in 2017.

"It's an amazing achievement for Giles. He really has been totally dominant," Ainslie told BBC South Today.

Scott finished eighth and second in his two races on Sunday to take an unassailable 24-point lead into Tuesday's final medal race.

"To win gold without having to even compete in the medal races is rare," Ainslie added.

"It's a huge credit to him and his coach Matt Howard. I know how hard they've worked, not only over the last four years, but before as well to get to that point.

"I think he's totally dominant in the class right now. I know he wants to pursue other areas in his career, such as the America's Cup.

"But it's entirely down to him. He could certainly dominate the class through the next Olympic cycle and further if he chooses to."
