There is a continuing debate on Sailing Anarchy with the Phoil Phanatic Doug Lord about foils, wands, and flying. I recently posted this list of things we did in camp Stevo while trying to make moths foil:

"Here is a list of at least some of the experimental foil setups Andrew and I tried up to about 2005:
* Bow rudder and foil plus main foil, no wand,
* Manual incidence control of bow foil.
* Bow and stern ruders with centreboard, foils on bow and board.
* Bow and stern rudders with foils and no centreboard at all.
* Foils on CB and rudder, no flap no wand,
* Foils on CB and rudder, trailing edge wand on both,main foil with dihedral to induce righting moment with leeway.
* Manual adjustment of main foil incidence,
* High rate manual rudder flap adj, via tiller ext for reaction to waves.

We were the only people in the Sydney Moth scene trying anything at this time. There was not a lot of sucess from these experiments and only a few ideas are worth saving for the future.

We then went to the Melb Moth 2005 WC and saw how well the Ilett system worked, talked to John who was very generous and helpfull, and came home and started doing it his way.

With the exception of Andrew's tilt rudder system adopted by the Bladerider all of our subsequent work on moths has been in learning how to make the foils as strong and as light as the professionals.

We have tried and will develop some more ideas to try WRT to general moth layout but for now we are content to make only subtle development changes to the foil system. "
