The problem with this is I'll end up with a vertical wave breaking infront of me. There is also no time for me to run and go above the wave before it crashes. So I tried to do a turtle roll without padding no time for that. The wave rip the board out of the water with me flying along with it ....cant recall what happen after this but I survived

So what am I supposed to do in such situation? I can ditch when no one is around but I'll get drag back. I can hold the leash and try to sink the tail a little while diving under but it's straining my hand...
Question on turtle roll....
When doing turtle roll are my hand suppose to be straight or bend 45degree?
Where am I supposed to hold the board? I hold it on where I do my pop up.
I feel my face is being forced towards the board when I'm under. Either that or the tip of my head is threatening to hit the board.
Does it not work if I don't paddle?
Pls help many thanks!
