My experience is if you do not stall the rig (as described above) before the puff downwind or making the transition you will pitchpole or capsize.
Letting the sails out or stalling the rig after the puff does not work in the higher wind range. And a crew member can call the puffs.
The wind speed at the tip is what 40nt?, and having the boards up would help:
however, the wing has 2x(+) more lift than a beachcat sail, so all the more importance to stall the wing.
