The international Inter-Service Regatta, the Beaufort Cup, will be held during Volvo Cork Week, including an overnight race around the Fastnet Rock.
The third edition of the Cup organised by the Royal Cork Yacht Club will include a 'wealth of international teams' racing for charity.
The Cup is open to national and international teams from the RNLI, Navy, Coast Guard, Army, Airforce, Police and Emergency Rescue Services.
Inshore racing will be held on different style courses every day for the prestigious Beaufort Cup in honour of Sir Francis Beaufort along with €10,000 to be presented to a charity of the winners choice.
The Harbour Race will take place on Wednesday 13th July with spectacular racing in Cork Harbour for the fleet.
In previous years, both local Crosshaven and Baltimore RNLI lifeboat crews have taken part in the race.
The RNLI have in the past been the recipient of the charity donation from the winners.
A Notice of Race for the Beaufort Cup will issue shortly.
