The event is the usual Sunday Race for CYCA yachts taking part in the Brewin Dolphin Scottish Series, but is now open to those unable to take part in all four days of racing over the bank holiday weekend.
The race sees yachts setting off from Tarbert, sailing round the southern part of Loch Fyne before rounding Inchmarnock Island and finishing at Tarbert.
Interested sailors are invited to log on to www.brewindolphinscottishseries.com for more information and the entry form.
Johnnie Readman, event organiser, said "We decided to open the Round the Island event to encourage those keen to take part in the Scottish Series but aren't able to assemble a crew for the whole weekend, to sign up and get involved for one day.
"It's set to be a great event with a good number of yachts lined up already. What's more, being in Tarbert on the Saturday and Sunday nights means sailors can take part in the shoreside festivities Tarbert is renowned for as well, including fireworks on Saturday and an aerobatic display on Sunday."
The 2011 Brewin Dolphin Scottish Series takes place over the bank holiday weekend from Friday 27 to Monday 30 May in Tarbert, Loch Fyne in the Clyde Estuary. Three race areas on the broad waters of the Loch will provide separate racing for IRC classes; One Design classes and CYCA classes (with and without spinnakers).
