Steve, Harry, and Web Gang:

I did my best to maintain a weight balance in the boat, but I always kept weight
forward instead of aft so that the transom came out of the water, presenting a
much cleaner hydrodynamic planform. Also, weight forward allowed the fore chine
to do its job and keep things dry.

Steve, this is GREAT advice and you are right; it works for Sunfish and AquaFinn
racers and it will work for lateen rigged P15s. I would add that if you raise
the centerboard just a smidgen so that there is around 85% of the board still
down and the centerboard arm is forward of vertical, you'll find that weather
helm is reduced even more. This, combined with the tips you gave above and
keeping enough weight forward to get the transom out and clean would be ideal, I
think.
