Keep sailing it till you got it beat.

Practice, practice, practice.

Or maybe wax on, wax off.

I raced a 29er for a long time up untill around 2years ago. Awesome boat and great competition.
We had the skipper on the main sheet 24/7. I as crew was continuously trimming the jib and had my other arm over my head, standing tip toes when trapping.
Very important to call wind preasures for the skipper as they can't see that area.
Best training tip would be to sail the boat to windward so when a gust hits the boat will be level out, alot of speed is lost when the boat leans to leeward.

When going downwind boat needs to be flat no matter what, any tilt and the rudder will cavitate and you will be in the piss. When gybing it's important in moderate and light winds to give the kite a small pump in the sheet before pulling the other side. This will bounce the kite around the forestay, and you should be able to get the kite to pop as soon as it hits the other side.

I promise you that a mast tip will be broken soon

Thanks for the tips guys, we have improved alot, next time we go out I will take the GoPro camera and get some new footage :D

I have always wanted to get one, but they so expensive and brake everything you go out!
