Over sheet
Look backwards
straight front arm
flip early
Look backwards!!!
Did I forget to mention I'll be learning in 2-3 feet of chop?
Yes. Look backwards. It does a few things
Oversheet ...depowers the sail
The look backwards gets you to look in the direction that you are going to travel in, it gets you to move your hips and shoulders in the direction of travel ( helps turning )
Slide hand forward and flip
I recommend that you find some flat water to start with
