Sanita Puspure and the men's pair of Philip Doyle and Ronan Byrne did the business at the World Championships on Friday morning to send two more Irish boats to the Tokyo Games, while pararower Katie O'Brien delivered Ireland's first medal.

Puspure won her women's single sculls A/B semi-final to seal her qualification for next summer's Olympics. Puspure needed to finish in the top nine overall in Austria to ensure she'd be heading for Japan and did it in style.

Earlier Doyle and Byrne won their A/B semi-final to guarantee they'll be on the plane next year, following the lead of lightweight double sculls duo Paul O'Donovan and Fintan McCarthy, who qualified yesterday.

Meanwhile 21-year-old Galway woman O'Brien took bronze in the final of the PR2 event to crown an excellent week on the water in Linz.

Gary O'Donovan took fourth in the B final of the men's lightweight single, Lydia Heaphy was fifth in her women's lightweight single B final and the men's lightweight quadruple crew of Hugh Sutton, Miles Taylor, Ryan Ballantine and Jake McCarthy took second in their B final.
