Hi Gary,
How tight do you sheet the spin in with that wind and choppy waves?
On the Global Challege and on other occasions I always nose-dive my Blade and I find it hard to gain speed with the spin up.
We have been experimenting a little in those conditions and trapping seemed to help although it's quite challenging.
I also found that sheeting in the spi more than neccesary (harder than the 'kilgrens' -> Dutch guys help me out here) stopped the boat also from nosediving.
All ideas are welcome.
Regards,
Gill
