Also competing during the second half of the National Championships is Micah Wilkinson, who won the Red Bull Foiling Generation 2016 and the pair went on to win the 2017 Flying Phantom series of the Extreme Sailing Series with his partner Olivia Mackay. He is currently pursuing qualification for the 2020 Olympics.
"We're trying to get 12 races in during the four day regatta, but it is weather-dependent," Harsant said.
"It has been a really high calibre of competition, it's fantastic.
"From Rotorua we've got Ben Davy, he's sailing his father's boat, he'd be one of the youngest. It's really exciting to see the young ones coming through. The oldest is Ken [Urquhart], he's in his early 60s, we've got the whole range."
He said Rotorua was ideal for holding the championships and Bruce and Sue Davy, of the Rotorua Yacht Club, had been great hosts.
"We come down here every year to do the Rotorua sprint regatta and they let us keep our boats on the lawn each year, they're fantastic hosts. Rotorua Yacht Club is such a great place to sail at, we really enjoy it.
"Lake conditions are totally different to sea conditions, just being so shifty and gusty, so it's been a good workout for all of us."
