Learnt a lot about these London Powerboat Club people this weekend - they also trade as Atlantic Web, and hire out unlicensed, uncoded RIBs

Once more for the search engine....
London Powerboat Club
Atlantic Web
Hamble Harbourmaster has a file on them, and I think the MCA are interested in them as well.
