i keep practicing this feet together shoulders forward stance style and its getting easier,
but not easy to maintain concentration for long, and it does need focus as you are constantly on the edge of balance or wobble, its great for pointing high upwind compared to toeside on your weak side, and it feels smooth as you fly round.
I know the method i am adopting is helping me improve, i can tell my overall board handling has improved due to me pushing myself into awkward positions and balance points,
but no surprise I never managed to get into this position or achieve even one foot switch a few days ago when out on a very high sea,
large crests everywhere and crazy turbulence all conspired against me trying anything not totally dialed in.
its all good fun.
Never tried the water start in this position but will try. I have however really enjoyed as the others said the ease of cruise. With so little change to body position during jibes. If practiced more I feel it will add to my foiler's flab.
From 1:20 in this vid I'm practicing this move. https://youtu.be/5Pu1_py96SY
Moving feet around is all about countering forces. If you bring back foot forward you'll need to give a little rear foot biasfirst then unweight yourself using the kite as you step forward. If not the board will nosedive as your balance moves forward.
