Ireland will send a team of 11 crews to the World Rowing Championships in Austria, with several rowers competing for a ticket to the Tokyo Games.
Olympic qualification is possible for seven of the boats on the waters of Linz. The action starts on Sunday.
The recently formed lightweight double of Paul O'Donovan and Fintan McCarthy are among those rowing for their place at the Games.
They will need to finish seventh to make it but head over in good form, having taken silver at the World Rowing Cup Regatta in Rotterdam in July.
McCarthy finished fifth in this category with Jake McCarthy at the European Championships in June, while O'Donovan won gold with brother Gary at the 2018 World Championships, and silver in the Rio Olympics three years ago.
Gary will compete in the non-Olympic lightweight single.
The women's pair of Monika Dukarska and Aileen Crowley need a top-11 finish, while men's pair Mark O’Donovan and Shane O’Driscoll also must finish in the top 11.
The heavyweight double crew of Philp Doyle and Ronan Byrne are searching for a top-11 ranking to keep their Olympic dream alive, while the women's four of Aifric Keogh, Eimear Lambe, Tara Hanlon and Emily Hegarty need to finish in the top eight.
They competed in the World Rowing U23 Championship in July and brought home an impressive silver.
Reigning World and European champion single-sculler Sanita Puspure needs to come home in the top nine.
Meanwhile the lightweight double crew of Denise Walsh and Aoife Casey require a top-seven finish.
