Ireland had a superb morning on the water in Lucerne as the women's four team and the lightweight women's double team both qualified boats for the Tokyo Games.
The quartet of Emily Hegarty, Eimear Lambe, Aifric Keogh and Fiona Murtagh produced a superb performance to win their final at the Olympic qualification regatta in Lucerne, finishing clear of China and Italy.
"We're absolutely relieved," Lambe told World Rowing's official website.
"It's been a long time coming. Although on paper we were probably one of the favourites, anything can happen on the water. We are so happy."
The lightweight women's double team of Aoife Casey and Margaret Cremen then followed suit as they came third behind the United States and Switzerland in their final to ensure Olympic qualification.
A jubilant Casey said: "It's so surreal because I feel like we’ve worked so hard the past two to three years.
"We came in as underdogs. It just shows what you can do. We came from behind and all we wanted to do was do our best and we are so happy."
There was no joy for Daire Lynch. The Clonmel man finished fourth in his A/B single scull semi-final to miss out on the final.
Ireland have now qualified six boats for July's Tokyo Games.
Rowing Ireland's high performance director Antonio Maurogiovanni said: "We are very proud of all of the performances from our athletes this weekend, and all seven athletes gave a brave and spirited effort in each of their races over the two days.
"We are delighted that the Women’s Four and Lightweight Women’s Double qualified their boats for the Olympics this summer.
"All of the team performed strongly this weekend. Daire narrowly missed out on the final and gained invaluable experience this weekend that will benefit him for Paris 2024.
"We have six boats confirmed and qualified for Tokyo, and we continue to train and prepare for the upcoming Olympics. Having these six crews qualified at the next Tokyo Olympic Games has put Ireland in a very challenging and exciting position not just for Tokyo but also for Paris.
"As we all know, this is also year 1 of the 2024 cycle and the current Rowing Ireland squad, if well supported, has everything to keep the fantastic momentum going."
