All Ireland Junior champion Chris Bateman leads Class One of Monkstown Bay Sailing Club October Dinghy League after the first two races sailed from a boat start in Cork Harbour on Saturday.
Second in Class One's 18-boat fleet is fellow Laser sailor Brendan Dwyer. Alex Barry and Sandy Remmington are third in an RS400.
Despite the Laser Munster Championships being sailed on the same weekend at nearby Kinsale, 11 Lasers opted for the popular MBSC League with a cash prize.
A six boat Class Two is led by Laser 4.7 sailor Harry McDaid.
Provisional results are here.
