"We are looking into the possibility of raising the cap," said Byrne, who described the massive subscription as a "high-quality problem".
With 120 boats, the fleet would likely be broken into four groups for qualifying rounds, sailing on two separate courses, but Byrne said that the SIs had not been written yet, and with the possibility of further entries, "nothing is set in stone".
He said the committee was also looking into various options for dealing with berthing and on-shore facilities, including modular breakwaters in front of the National Yacht Club to house the fleet.
" We are looking to put as many boats in front of the club as possible," he said.
"We are working on a solution with Dublin Port, one of our main sponsors. They hav ethe capability to put this together, but we have to have a consultation process with Dun Laoghaire."
He said that other clubs on the Dun Laoghaire waterfront had offered whatever assistance was necessary to help the event go smoothly.
Byrne urged those eager to sail in the event to register to join the waiting list for cancellations or a possible extended entry. He said the committee will happily transfer entries up to two weeks before the event. Joining the entry list is free of charge and is understood to be building fast.
"We opened at the end of January and when we got to the end of last week and it was full - it took around a month and a half," he said. Entries were originally due to close on June 1.
