All a one design class needs to be successful is a sanctioning
body making it THE choice for contests. Look at the olympics.
Solings for gods sake, tornado's and other low performance
boats. Very strict rules on planform and construction. IMHO
there are much better race boats in the world than what theey use.
The key is that they use them, have contests and promote it as a
class boat.

The PW5 only needs for the sanctioning body of soaring to adopt it
and have a world championship at the venue that the other classes
are held. There are people who would fly for a world title in the class
if it was flown and promoted that way.

Scott.
