The MV Isle of Arran will become the first CalMac ferry to circumnavigate Ailsa Craig this weekend when the 35-year-old vessel makes the charted voyage for Clyde River Steamer Club (CRSC).
Setting off at 11am from Ardrossan, the vessel will make its way to the 99 hectare island which lies 10 miles west of mainland Scotland, south of Arran, and return at 4pm.
One-off trip
