Hey Tom,
Try putting your paddle across the front of your body so the blade is dragging on the face of the wave near your heel side rail. The handle should be in your left hand.
Doing this should:
- let you 'feel' the wave and your board's relationship to the face (because it's harder to 'see' this on you backhand)
- force your upper body to twist around and point forward (don't move your feet around though - just your upper body) again so you have a better perspective of what is going on
- give you a bit of balance as you will now have a third anchor point for your body
- allow you to control your speed a bit without needing to turn or stall (just dig the paddle in deeper).
Warning: Be careful not to dig the paddle in too deep while going fast on a decent wave, you can put a lot of pressure on your shoulder joint.
Once you're in this position you can gently climb up and down the face using your feet and legs. Go as big or as gentle as you feel comfortable.
If the wave fattens out, you can switch hands/sides with the paddle and pull into a big cutback (now with the paddle dragging on your toe side). These are fun.
I hope you find a fun, gentle right hander to practice this on soon - like, very soon - maybe even tomorrow!
