I think there are some discrepancies between the timetable on the Calmac website and the one on the Argyll and Bute website which you can find on islayinfo.com. Since A&B council is running the service I'd put my money on their timetable instead of the Calmac one. And if you're not sure why not call the ferry operator on 01496 840681
The Maggie is one of Ealing studios lesser known comedies. A wily old skipper of a Western Isles 'Puffer' and his motley crew lead all who come into contact with them a fine old time! Many scenes on Islay!
