Strong winds are expected, which will help the boats reach fast speeds.
He said: "It's really fast, high impact, exciting races that last about 10 to 15 minutes. 
"We do three races a day so it is all done in an hour and a half window. 
"It's sailing like you have never really seen it before."
rews wear safety equipment including helmets and goggles because of the speeds they reach.
"There is nothing compares to getting up on the foils and getting close to 100kph," Mr Ainslie added.
"There aren't many power boats that can go that fast let alone sail boats. 
"Its phenomenal and incredibly exhilarating."
