Michael O'Connor, Davy Taylor and John O'Driscoll lead the 2021 SB20 East Coast Championships by eight points after three races sailed off Dun Laoghaire Harbour.
Dublin Bay presented 12 to 18-knot breezes from the southeast with a mist and fine drizzle.
Testing championship conditions for the 12-boat fleet were completed with a good chop, though the sheltered Seapoint racecourse protected the 20-foot keelboat class from the bigger waves on the Bay.
The Dublin trio is well clear of Royal Cork's Mel Collins and Aidan Mac Sweeny in Gold Digger who is just one point ahead of Royal Irish's Ger Dempsey and Chris Nolan in third place on 12 points.
As regular Afloat readers will know, the Irish SB20 fleet is gearing up for next year's world championships on Dublin Bay, a year earlier than originally planned.
It's a change that also sees the Irish hosted World Championships switching venues at Dun Laoghaire. The event now moves from the National Yacht Club to the Royal Irish Yacht Club, which is hosting this weekend's Eastern Championships as part of its world's build-up.
Racing continues on Sunday.
