Welcome to the Forum, young man. I, too, am unable to comment on your particular RIB other than to note that your engine is a direct injection 2-stroke and 5 times larger than mine, so it'll be bloody quick
There are a growing number of forum members who use their RIBs on the Essex coast - we launch just over the water from you in Bradwell - so if you're interested in slumming it with sub-5m RIBs, keep in touch. Naturally we have little chance of keeping up with you, but we do like to include a large RIB in the flotilla specifically for towing DanielTD5's Valiant when his Mercury breaks down again.
