wildthing is great fun, but you have to make sure your sailing efficentley and falling in as little as possible.
Don't sit on the leward side as a helm. On the leward side you will be uncomfortable as you are always worrying about going in which in turn means you wont be trimming your sails as well as you could and you wont hav eyour head out the boat enough.
Sit on the windward side (to windward of the mast, most often on the tramp) as far forward as possible and in control.
Dont try and wildthing too early, u'll just end up reaching everywhere.
When you do start flying a hull pull the travler up a bit as the apparent comes forward, make sure you can fully steer, trim the main slightly, easeing a bit in gusts to give the boat forward momentum not just hull flying, try and keep the hull low just a few inches to a foot of the water as that is the most efficent height.
