To qualify, your wingspan must be 13.5 meters or less.

Being new to racing and owning a 15 meter moderate performance glider I'd like to understand the reasoning behind the 13.5 m limit.

I entirely understand the appeal of a race limited to low/moderate performance gliders, but why not use the handicap number to limit entries?

For example, a glider that had a similar handicap to the PW-5 but longer wings would be included. For an extreme example, this would include the ASK-21. Similar handicap, but much longer wings.

I always figured that performance, and not size, was what mattered
