Winning the Class 3 title with the lowest score of any of the five classes, Jonathan Skerritt's Quest from the host Royal Irish Yacht Club counted three race wins and two second places in a highly consistent performance over the three days.
Neighbouring club sailor Nigel Biggs on Checkmate V had a similarly low-score with four race wins and though a fifth in yesterday's third race spoiled the straight run, the Class 2 national title went to the Royal St. George YC.
The smallest of the national classes was won by Declan Ward's 28-footer Chouskikou from Dun Laoghaire Marina competing on ECHO handicap.
A fourth race was added to Sunday's programme that then ran late into the afternoon for the two big-boat classes with the Royal Cork YC taking both national titles.
Denise Phelan's Jump Juice won Class Zero with a comfortable ten-point lead thanks to four race wins and two second places. Ian Nagle's Jelly Baby won the Class One title for the second time since 2012 though with 26 boats in this fleet, the win was less straight-forward despite three race wins.
Meanwhile in Cowes, the British IRC National Championships was won outright by Anthony O'Leary on Antix in a large Class One turn-out of 20 boats. The Royal Cork YC skipper is captain of the ICRA team in this year's Brewin Dolphin Commodores' Cup at the same venue next month.
