There is not much info as the last bolts were fitted Friday 19/09. The boat needs to have the Yamaha's replaced by two Mercury 300XS. They're lighter. Besides thh weight the 25 pitch prop on the Yams doesn't release all the potential. In less than 15 seconds the rib reaches 62 kn and then there is no more. Kris (managing director of Brugge Marine Center) will invest more time to tune the boat for it's optimal performance.

Kris told me almost 65, he told me they got 3 more knots after 62 in 15 seconds, than there was over revs on the engines.

Hull shape is made so transom has the same function like a jack plate.

Setback? Surely there's no lift function?

mmmmmmmm..... computer, CFD program, and then test tank, then come back and tell me that again.....!! sorry not really possible to design a hull to imitate a jack plate -
you can tweak a hull a lot of ways like.......:

stepped hull = yes,
vortex generators = yes
draglets = yes

By fitting the engines on a jack plate you would move the datum aft and the centre of pressure further aft thereby shifting momentum forward.. has it got a water pickup and bow ballast tank??

still looks like fun tho....... but looks too heavy and a little slow for my liking.....

I think what Petrov wanted to say is that the rib has an integrated engine bracket similar to the one in this post: http://rib.net/forum/showthread.php?...hlight=setback

Yes, thats what i mean, thanks.

ok........... iv'e not helmed an engine bracket like this configuration - so cannot comment - but struggling to see from the design the benefit.....? - just looks like more weight, and a lot more drag in the exact place you want less drag?? - maybe its my intepretation of the photos?
