Read an article about a group of guys wind surfing across the Atlantic, they had a large safety vessel equipped with around 6x22' with low powered engines in the seas encountered some of the boats became unusable as they could not maintain any forward motion against the seas... I can not really remember any small details thou as it was many years ago

Hope not, the RN have been using them for both routine and emergency stuff on board there ships for 25 years. The specification didn't change much during that time so presumably the RN felt Halmatic got it right the first time.

For the private user if your happy with a 25 knot cruising speed then a P22 will get you into a diesel engined rib for 10-12k depending on condition and that has to be tempting.

As for the Prosport well it might be a nice cruising boat. Remember Alan Priddy crossed the Atlantic with a 7m rib and 165 hp, without a good sea trial your never going to know what she is like.

You mean this race in 1998. I remember tales of problems getting them on and off the ice-breaker that they were using as the support ship but not of them being underpowered. I can ask the question though. (They had some awesome conditions if you can find any video or photos of it you'll see what I mean!).

I'd forgotten all about that farce. The 98 TAWR was a huge success for sponsors, the sailors that did it etc. I went down to Weymouth to see them in and the reception was good. Even more incredible to see Robert T (the madman from New Caledonia) jump from the bridge of the Icebreaker into the
bay, about 80ft!

130hp not enough to push a 7m RIB through the water?

http://www.boatsandoutboards.co.uk/view/CUX014

This tug only has 200hp and is also an icebreaker!!!

Many displacement craft only have low hp engines - torque is so much more important. I used to go out on an old wooden trawler - 50' long - weighed 25 tons and that engine was only 150hp - had no trouble in rough seas or pul;ling massive nets.

Yeah, that was hugely geared down and spinning a 3ft prop, it might've done 8 knots on a good day. C'mon Codders, I know you're not that daft.

Nah it was 5' actually!!!

I know these are extreme cases but I would suspect that a 130hp diesel would have far more low down grunt for rough water work than a petrol engine operating at similar speeds.

Possibly, but this is a rib . There aren't too many displacement ribs, although this could be one.
