Like Armin said Theo, Machir Bay is on Islay's west coast. This here is Claggain Bay, I had a feeling you'd been there since it's not too far off from where you stayed. Worth visiting next time you're over!
Here is a picture of Machir Bay, not the best one but it will do:

Claggain Bay, south east coast coast, southern end, looking south west.
This was an easy one for you Armin, I will try to find a difficult one for you when I return from Islay
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!
