Where J109s are holding sway in Class One and Half-Tonners in Class Two, Class Three of the ICRA National Championships on Dublin Bay has a refreshing mix of design types at the top of the Royal St. George Yacht Club hosted championships.
And in a shock to the established Class Three pecking order today, Howth's X3202 Dux (Anthony Gore-Grimes) has taken the overall lead in the biggest fleet of 22 boats after some fine sailing produced three race wins to lead Carrickfergus's highly modified Beneteau First class 8.
Toppling the Northern Ireland boat - even by a single point - is no mean feat, the Rory Fekkes skippered black boat was the winner of Cork Week overall last year and last month Fekkes was the winner of every race, bar one, at the Scottish Series.
Third - but seven points adrift of second overall - is the host club's Impala Running Wild skippered by Brendan Foley.
Results are here. The final two races are scheduled tomorrow from 11 am with breeze forecast to be westerly at eight knots on Dublin Bay
