Here's a more recent tube ride. In the first two frames she's taking off and setting up. Her body position is much better and centered over her board.
In the next two frames she's golding her line aiming through the tube and not trying to straighten out . Her board is angled down slightly and she's maintaining her head high.
Here's where it is important to keep your confidence and balance. Most tubes aren't "perfect" so you'll have to keep your balance to get through the tricky sections and keep proper momentum so you can exit the tube properly. Good luck!

My friend Bathany Hamilton got to stay at my house for 2 nights. We surfed a lot of good spots.

Then the next day I surfed Big Rights. It was awesome, my first day out at the spot and I loved it. Maybe, nexxt time, Bethany we'll go there. You'll like it...
