I see those types of boats regularly racing through Poole Harbour, plus a stealth powerboat, even seen them being dropped from chinook helicopters in Poole Bay.
I did try and race them a few years back but weather was against me and they don't care and gave em full throttle into some nasty waves. So a frequent site, if others seem them racing through Poole Harbour my advice is keep out of their way as 5 of those big ribs fully loaded up at speed makes a very large wash.
