The mixed crew of Alana Twomey and Chris Bateman of the host club clinched the 29er Southern Championships at Royal Cork Yacht Club.
The Crosshaven pair's one-point overnight lead was swallowed up when they posted a third in the first race on Sunday.
Twomey and Bateman won the final race of four sailed on Sunday but they still had to await the application of discards in the 11-boat fleet to see who emerged victorious.
