John Twomey, Austin O'Carroll and Ian Costelloe finished 14th in the Sonar medal race to sign off from the Rio Paralympic Games in 13th overall.

The Irish trio lay 13th in the standings after 10 of the competition's 11 races, and were well out of contention for a medal.

After a strong start that saw them fifth through the second marker, they faded to the back of the fleet.

"Conditions were nice out there," Twomey told RTÉ Sport at the end of his 11th Paralympic Games.

"We had a very good start and then the Brazilians came across and hit us and spun us around and that was literally the end of our race. By the time we got back on track the fleet was gone ahead of us. It was really unfortunate."

It was Twomey's final appearance and the Games and he admitted "it was probably not the way I wanted to finish up with that last race, but we put in a good campaign.

"Our two training partners took silver and bronze and we are just as fast as they are, we just didn't have the knack of dealing with the winds here."

New Zealand and the USA exchanged the lead before the Americans eventually crossed the line in first, with New Zealand and Israel behind them.

Australia took the gold, with the USA snatching silver thanks to that powerful final performance, and Canada just squeezing out New Zealand for bronze.
