Jonathan O'Shaughnessy leads Chris Bateman in Royal Cork's ILCA 7 Frostbite Series in Cork Harbour.
After six races sailed, O'Shaughnessy has built up a four-point winning margin.
Wexford harbour's James Murphy holds third overall.
The Lasers and RCYC Topper fleets sailed on the Curlane Bank on Sunday under Race Officer Tom Crosbie.
Nine ILCA 7s are competing with ILCA 6s also in the mix.
This is the first year for some years that RCYC has had a full rig in its Frostbite Series as some of the Topper and 4.7 Laser sailors graduate to the bigger rig.
Results below.
Next Sunday will be the last of this series, with a prizegiving at Crosshaven after racing.
