The South Coast Offshore Racing Association (SCORA) has cancelled the Kinsale-Fastnet Race scheduled for July 28.
SCORA Commodore Daragh Connolly said: "We have a huge number of sailors from the South Coast competing in the Rolex Fastnet Race, and we wish them safe passage and the very best of luck.
"Given the level of sailors away, we are standing down the Kinsale YC/Fastnet Race.
"However, we will hold a "pop up" long day coastal race (six hours approximately) on Saturday morning, July 29, from Crosshaven. All boats welcome."
Details of this will be issued shortly.
There will also be a Kinsale to Baltimore race for boats going to Calves Week Regatta in Schull on August 5.
