In 1980, West Highland Yachting Week entered into a 30-year-long sporting partnership with Tennent Caledonian Breweries, probably the longest sponsorship ever of a yachting event.
In more recent years, the JRC has formed a firm association with Tunnock’s who have acted as the main sponsor of the regatta and the famous Scottish biscuit manufacturers will be the headline sponsors of the 70th anniversary event. Additional sponsorship is provided by Argyll and Bute Council from which the Argyll fleet takes its title, and Tobermory Harbour Association. More recently support has been added from Owen Sails, Malin Waters, Gael Force Marine Equipment, Scottish Canals, Dunstaffnage Marina, Webcraft UK Ltd and Birlinn Books.
Boyd Tunnock CBE, grandson of the founder Thomas Tunnock, has been a regular and successful WHYW competitor in his Moody 38 Lemerac.
