Just to clarify the reason for the change of web address.
Quote from the "AIS" webmaster ... "what happened was the hosting company suddenly put a firewall on their server to prevent frequent site updates. The actual site was split between 2 domains - all a bit historical - ais-live and solent waters but you would not notice unless you looked in the URL bar. Rather than to transfer domains around it was easier just to combine all the site into one new domain and go with a new hosting company who could handle frequent uploads. Unfortunately the firewall locked me out so I couldn't put a redirect on the ais-live site!"
