BTW, be interesting to know at what speeds other boats get on the plane and stay there?
We have a stepped hull on the Cougar..The handling is awesome..We can hairpin turn at 50 knots plus...getting on the plane is very quick aswell.
You need a powerful motor though to get the benefits.

Tony,

After watching the videos you put in the power-racing part of the forum, I wouldn't mind your boat myself to dash backwards and forwards from Guernsey to Sark. How does it hold up in nasty weather to Carteret?

At what speed does it goes on to (and fall off) plane?

rupert
p.s. Lovely looking boat!

I would disagree with you on that Tony - a stepped hull that is working correctly will be faster than a regular Vee meaning you can have less power and perform the same!

Most of the others have a category B. Now we all know that these ratings mean very little practically, but this detailed explanation (they don't just state Cat. C, but also go into some depth as to what Cat C. means and the kind of seas you can use it in) is interesting.

Having said that, some of the reviews talk of trips having been made all around - Wales, and Southern Ireland.

One thing I am not convinced of is what, in the picture, looks like a stepped hull. A concept which, BTW, has been violently slated (being described as showy nonsense) in this month's equivalent of Rib International. They consider it as being dangerous when loading onto trailers, and ridiculous on a rib in heavy seas - comparable to having a spoiler on a Land Rover! Albeit, they accept that the stepped hull has its merits in racing. The article also shows a picture of a stepped hull rib turtled and remaining so.

Having said that, I like the look of the Shearwater.
The Shearwater hull is designed by Ring who certainly know a thing or 2 about hull design!!!

I am not sure if the Shearwater hull is stepped???

There are good and bad stepped hulls just like everything else. They tend to work best at speed in short chops.

Just look (and listen) at this Revenger with an Ilmor V10 - almost 90mph!!!

I agree with you about Ring, although I have seen quite a lot of Ring boats for sale recently. I would have thought they would have been snapped up quick, and that is not the case.

I also do like the Shearwater, especially the cabin.

I have no problem with rough weather..My rib is designed for speed, so it would not perform as well as a larger toobed barge.......lol

Why have a less powerfull engine when you can have a bigger engine performing better and which runs more efficient at high speeds?
