Race Officer Barry O'Neill will try and get the first races of the 16-boat SB20 Easterns underway this Sunday lunchtime after cancelling Saturday's programme due to lack of wind on Dublin Bay.
O'Neill says there is no point in planning an earlier start as the forecast for the morning is poor.
O'Neill and his race committee went to sea on Saturday at 9.30 hours but kept the fleet ashore using a rolling AP.
Even though a gentle five-knot breeze filled around the Bay's East Mark at noon and the fleet came out, it was to no avail as, by the time they got to the race track, the breeze had turned off.
The fleet returned to shore without racing at 2.30 pm as per the Sailing Instructions.
Royal St George Yacht Club event organisers had planned to run more short races in a new format Championships, but this looks likely to be curtailed by the light winds.
A change to the sailing instructions has been made to extend racing until 4 pm on Sunday to give some chance of completing a series.
