My Internet searches for information on United Kingdom fishing boat ports of registration has yielded little in the way of information. One source that I have found states that the registration letters RO relate to the Port of Rothesay on the Isle of Bute in Scotland. If RO 105 Freedom featured in this image did come from Rothesey then when I captured this image of her crossing the Solent Southampton in June 2010 she was a long way from home!
