Ewan McMahon and Finn Lynch have progressed into the Gold fleet for the top 52 competitors at the Laser World Championship in Japan that is a qualification event for next year's Tokyo 2020 Olympics.
Six races over the coming three days will decide the finals standings and the next five nations to be included for Japan next year.
While Co Carlow native Lynch scored two top 20 places earlier today to stand 50th overall in the 156-strong fleet, it is McMahon, from Howth, who has the best overall Irish placing in 41st place following a 14th and 13th for the day in his first senior World Championship in the class.
Liam Glynn from Bangor was unable to find his opening day form and lies mid-fleet in 77th overall.
