Seriously though that looks painful AND expensive. Everyone okay??
Looks like my speed is my "driving style" and not the boat set up...

Stef it takes a speshul knack to be able to get it that shape. Basically you have to drive as fast you can at something solid.
Can't believe just the one leg got it. Not a mark on the bottom so christ knows what I hit.
Boat hooked straight over on it's side from the leg driving at a funny angle and the next thing I knew was having the wife taking my jewels in her hand and explaining that she didn't like the experience. No sense of adventure I'm afraid
Anyway Volspec are £2500 richer and I'm the same amount poorer. All rebuilt just waiting on one more part tomorrow and back in all done so only 7 days lost
Anyway your boat. I think there's some odd claims on here about 45 knots all day long etc. You need to be realistic about your actual speed.
The difference between empty and full tanks will be close to a tonne.
You will no doubt be carrying at least another 500kg of bits and bobs that aren't there on a bare boat out of the factory. Think fenders, lifejackets, bedding, gas canisters, provisions and of course the drinks cabinet.
Are you on ally or stainless props. Worth possibly 2 knots.
Have you stripped the covers right off or left part up and furled the rest. Covers can account for another 2 or 3 knots.
Are you running with or against the tide. Our tidal races can be up to 6 knots around here and make a big difference.
With or against the wind. Again it will make a difference.
What speedo are you using. Forget about using a log, ring it up on your GPS and play with trims until you get the best with no tabs on at all except that needed to keep the boat level.
If you are putting one tab partly down to counteract any lean then that will knock speed off.
It is possible to trim the engines differently to take out any tabs used to balance the boat and sometimes this is more efficient.
How clean and polished is your bottom. You may just have been antifouled but this time of year round here just a weeks worth of growth will take 1 or 2 knots off until you have cleared it.
How much toe in have you got on the drives. Fastest is no toe in but not very driveable. Too much and you are not getting the power put to best use.
Then have a play with something like this and you see that probably 40 knots is what you should be aiming for.
