Oldie,
I'm banking like a 90's entrepreneur, that's not the trouble. Say I'm on starboard...
Blast along, pull back foot out of strap, put on leeward rail, push mast forward, sheet in and bank board. When it's pointing just past downwind, twist right foot out of strap and
place on centerline*, quickly put left foot in front of front straps, now it comes down to a choice of:
a) Forget to slide right hand close to mast
b) Forget to yank the mast as hard as I can towards me
c) Lose balance and fall off either 1) backwards 2) upwind 3)downwind
d) Run into the sandbank
It all comes down to practice I think, at least I've got flare gybes in low wind working. The more times I try it, the more ways of falling off I'll find until finally I fluke a working gybe. And THEN it's a case of replaying the tape, getting it working again, and then my plans for WORLD DOMINATION will finally come to fruition!!! MWA HA HA HA
* I was putting the foot too far outboard, and hence slipping off
