Fiona Young's Albin Express North Star of the host club is the clear leader of a mixed Volvo Cork Week IRC Three division on three points.
The Crosshaven helmswoman took three firsts, while her Royal Cork clubmate Conor Phelan, who scored 4,2,2 in the Quarter Tonner Anchor Challenge, is second.
Third is Royal St. George YC's Conor Twomey in the First 8 ALLIG8R on ten points.
Three windward leeward races were held on a course area southeast of Roches Point by International Race Officer Con Murphy.
