Hi!
I do not know to whom you are adressing this post, but I might help you a little bit.
We are a searaftingcompany,
www.fjordrafting.no, and we (ab)use our boats. We do own a 29 Revenger and it is extremely good. It handles the waves better than our 36 feet ribs. It is a dream to drive, it is very though built. My friend has a searaftingcompany called havrafting.no, and they have had their 29 Revenger for 3 years. This boat has never seen calm weather and nothing has broke. It is fast and it is steady. Last year we had an other 29 feet long rib and that could not handle the same high speed turns as our 29 with stepped hull. We will not tell you about the extreme turns we do beacause you will not belive it. But doing the same with our past boat flipped passengers over board. In the Revenger, we can do this turn all day.
We have already decided to order one more Revenger!
And about the engine, you will have to look very hard to find a faster hull. The Marc Pascoe-hull might be faster, but at a price three times the prise of a Revenger-hull. We know because we got quotes on both theese boats four months ago. A 300hp would give you around 52-55knots, depending what you want. (how high you put the engine, what propeller, what engine etc.)
Good luck!
