Sailplane Classes
Now I want to suggest that, in my humble opinion, the way the
classes are currently set up by the SSA don't make any sense. Lets
take a step back, reset our prejudices, and see if we can't make our
grey matter operate at a higher level than usual.
What do we know? Well actually quite a lot! A large heavy glider has
a better Reynolds Number for lowering effective air resistance –
suggests better L/D. All things being equal the L/D is improved by
having a high wing aspect ratio. A smaller light glider will perform
better in light conditions. Flaps marginally improve the extremes of
the polar and so on and so on.
I think when all is said and done the most significant parameter
that affects the overall performance of a glider is its weight! So I
propose that we consider just 3 classes of sailplanes based solely on
their weights.
Lets forget about wing spans, flaps and other enhancements. All 3
classes would be free to choose their own goodies as long as they kept
to prescribed weight limits. Wouldn't this make glider design so much
more fun?

So what you're saying is, as I interpret it, "It's the pilot's wallet,
stupid." It's not a bad idea, but some other constraint would be needed
to limit the cost, or soaring competition will become as relevant to the
regular sailplane pilot as F1 racing is to most car owners.

There is an often overlooked method to keep things affordable and
still let individuals be creative and innovative. Racing is racing, be
it gliders, autos, or pogo sticks and "claiming races" are one way to
keep things cheap. For those not familiar with the concept here is
how it works.

Set a cash value, say $25,000, on the glider class. The top 3
finishers (not including first place) have the opportunity to purchase
the glider that placed above them for the predetermined amount. In
this case $25,000.

A slight modification of this is that instead of an outright purchase
the gliders are swapped, with a smaller cash fee paid to the winner
loosing their glider. In this class the fee might be on the order of
$3,000 to $5,000. If it turns out that it was the pilot, and not the
glider, that was superior then at the next meet the original owner has
a reasonable chance to redeem his glide, if they want to finish one
spot back. If he still places ahead of his former mount then he has a
fairly comparable glider - and some cash in his pocket.

This works for other sports where there is a potential to dominate a
class with nothing more than a fat wallet. The trick is to make the
swap price steep enough to allow for some investment in "high tech"
without the fear that you will only get one use of it, yet low enough
that the average participant can come up with the cash when they see
the need.
