It is definitely possible to overdo outhaul with a lot of sails. It does make them less powerful but often they can also become twitchy, unstable with a severe on-off switch feel.

problem solvered, should have changed down, Doh !

20-25 knots i use negative to neutral on my 5.5 race sail.

25-30 knots i use neutral to a little positive.

Anything above 30 knots I start going with serious positive!

In the 33-37 range I go max outhaul.

In this wind my 3.3 Tushingham Rock would be much more fun.

Yes, in hindsight you should have changed down, but good on you for doing a bit of tuning (or detuning as it turns out) to try to get more range out of the sail. I know I can get a bigger wind range out of a sail by changing fins instead ( and doing a bit of sail tuning too).

You know know how crap an over outhauled sail feels, so put that down as a valuable learning experience.

Thanks for the feedback, I new it felt crap and was pretty sure I had overdone it for those conditions. I think I got away with it with the 6.5 because the only thing I had to deal with was being overpowered (flat water speed spot) but with the 5.4 it was a combination of overpowered, gusts and extremely choppy/swell water state that would have seen me better off on smaller sail.
I had already changed down boards from 90 to 82, only the second session on that board and really liking it, meanwhile my mate 20kgs lighter than me and with his 100+ board spent more time watching and ended up packing up because it was all to hard.
