I'll try what you said about having my back heel out on the flat part of the board when planing.
When you crave jibe the Rio where do you put your back foot when you step over for the entry? I started a good jibe yesterday but when I picked up my front foot to switch my feet the board tipped off the plane. My back foot didn't seem to be very far over cause I wasn't turning tight.
When there is just barely enough wind to plane should I have the daggerboard down at all?
Thanks for the tip about my back heel.
