If you don't have anything factual to say don't say it. If you are an idiot keep your mouth shut. Forum's are supposed to be supportive!
I built this RIB for efficiency and long distance cruising.
I have just returneD from a 150 mile cruise in the Bristol Channel and never once was I under powered.
Planing is at 3,000 RPM, cruising speed is 24Kn at 4,000 RPM and top speed recorded at WOT was 39Kn. More than enough for me and very difficult to use WOT on the sea in a F5!
By the way, fuel consumption is very low...the mots important thing to me.
