You're welcome, M.
That's Mike Deacon's latest, Hot Lemon 5. One serious boat, the current Round Britain record holder (under 30').
Mike hasn't raced that boat yet AFAIK, unless there was a class that he could enter at Cowes? I went out on his previous RIB once, in a F10, we averaged about 50kts. Awesome ride, a real experience of a lifetime! Both the previous boat and the current one powered by Yanmar 300's (I think the newer engines are rated slightly higher, 315hp)
Of course Ribnut was a windup!
