new Osprey Vipermax 7

After waiting for more then half a year I got my new Osprey delevered in september 2004. Have not sailed very much since. Didn't have the opportunity. The times I've been out she showed to be a rib with marvellous sailingcaracteristics. The only thing I'm concerned about is the fact that at coming down from jumping a wave the hull hits portside of the boat first. The position of the rib seems to be twisted like 10 or 20 degrees left. Does somebody know what I mean and is there - besides steering to the left - a remedy against it?

You have to compensate the turn of the propeller, try to do a quick turn on the steering wheel to the right just before the prop leaves the water (and dont forget to take the throttle of so you dont overrev the engine) than the boat will fly perfectly thrue the air

The other thing that makes this happen is trimming in to much!

The other thing that fixes it, is to fit a left-handed prop.
But maybe you cant do this with your engine?

An expert will tell us pretty soon, I am sure

Firstly you would have to run it in reverse - you can't do that for long unless you use a left handed gearbox ..........

And secondly if you do that it will just fall the other way!

Not an expert at all!

Firstly. Serves you right for not having a large diesel lump. Worked for me in Cyanide.
Secondly. If you will go and buy a Mamba-Samba petrol engine what do you expect?
Thirdly. Cookee, you are a bloody expert!
And fourthly......what about offsetting his engine. Would that work?

Oh no I'm not! I know more than some and not as much as others!

Yes offsetting the engine is possible but the trouble is it only needs to be a small amount ie 3/4 of an inch, and that means the holes are going to be close together!

It might also be disguising another problem - it may be an idea to try moving anything that can be moved over to the starboard side of the boat to see if it is just a weight problem, although the first and easiest thing to do is to try it trimmed out a bit - sometimes there really is an easy way to sort these things out!

By the way many people fit engines in the middle now - the only time it may be worth it is for an overpowered boat - but even then ..........

Thanks for all your advises. As soon as temperatures are acceptable I'll test it all out.
