Helensburgh sailor Lorenzo Chiavarini was pipped to Laser bronze on a rain and wind-affected final day of World Cup racing in Gamagori, Japan on Sunday.

And Rhu’s Luke Patience, along with Chris Grube, who were competing at their first major event since Rio 2016, fell foul of a jury disqualification on Saturday night which relegated them into ninth place going into the 470 Men’s finale on Sunday.

But with Typhoon Lan approaching the Japanese coast, the second of the medal race days had to be curtailed with just three of the scheduled five races able to take place.

The building breeze varied greatly in both strength and direction, making it a challenging day for both sailors and race officials.

Chiavarini had gone into the final day in bronze medal position in the Laser class, but with Australia’s Olympic champion Tom Burton breathing down his neck.

Just one point separated them in the standings with a gap to fifth place, and whoever came out on top in the duel between the two was likely to determine the final podium position.

Big wind shifts also saw delays to the medal race start, but once it got under way, Chiavarini and Burton separated to different sides of the course on the first upwind leg, with the Australian’s choice proving the favourable one.

He led at the first mark and every mark thereafter, and although the former Lomond School pupil fought back he couldn’t reel in his Australian rival. He finished sixth in the medal race, with Burton’s race win sealing him the bronze medal.

Patience and Grube were in third place prior to the disqualification, and ultimately their medal race was called off leaving them no opportunity to improve on their overall position.

“We came here really to kick off what is our Tokyo 2020 programme," Patience explained.

"It’s the first time we’ve really been back in the boat since the Olympics.

“It’s actually been a good week. It’s been horrible weather-wise with the rain, but it’s been good racing and we’ve been pleased to just get a series in.”

“We’re really, really excited and more importantly very energised for what’s ahead.

"We took a year off, and I needed that as it’s been 12 years without a break of doing the same. I’ve gained some great perspective, but more than anything else it’s about the hunger.

"I’m more mad for it than I’ve ever been I think, which is a cool thing to say at 31 years old.

“There’s less than three years to go, but having had that time away, I think I can compress a lot of work in a short space of time.”

Chiavarini and Patience were among 18 British sailing team athletes to compete at the World Cup.

They're now at the 2020 Olympic Games venue, taking part in Enoshima Olympic Week, which runs until Sunday.
