Went down there this morning entirely sober, to try and settle this. Voila!! Cathyg nailed it.

There is but one really practically located usable swimming raft, and there she be.

About 100 feet off the rocks by the Watersports shop lies another raft about half the size of the usual rafts. It looks like a moored boat from up the beach... it also looks like you could be pulling splinters if you were to use it dressed as intended at Club O! I suspect this one is for Watersports use... windsurfers, kyaks, diving lessons etc.
