Classic boats from across Europe will take part in July's Volvo Cork Week Regatta for the first time as they join the celebrations of the Royal Cork's Tricentenary.
Sir Edward Heath's Morning Cloud, since renamed Opposition, is amongst one of the early entrants in the historic boat fleet.
Morning Cloud was the name given by the former British Prime Minister to a series of five yachts that he owned between 1969 and 1983.
Royal Cork organisers have also confirmed The Atlantic Yacht Club of France will be strong supporters of the event, committing 20 boats through their GoToCork campaign.
The Notice of Race for the Classic fleet is currently being finalised.
