Does any country run competitions in the IGC Club Class?


Germany comes the closest.

The German national competition rules are essentially identical to the
Annex A (IGC) rules. Tasking and scoring are very similar. The
Germans still have a distance task. Their scoring formulas differ
insignificantly from those in Annex A. In the Club Class, they have
removed some gliders from the top (high performance) end of the list
and added many gliders to the middle and lower portions. Gliders that
appear on both lists have exactly the same handicaps. Here is the
German handicap list:

In the UK, the story is approximately the same. Tasking is identical
to Annex A. Turnpoint geometry differs. Scoring is different in ways
that affect day valuation. The Club Class list is derived from the
IGC list, but handicaps (called "speed index") are assigned by BGA.
Gliders are added throughout the list, and, unlike in Germany, no top
end gliders are removed. The UK rules, including handicaps, are he

In the USA, tasking is similar to Annex A, but with the addition of a
speed task with pilot-selected turnpoints. There are more safety-
related rules, and team flying is not allowed. Scoring is entirely
different, and penalties (esp. airspace) are more severe. There are
two classes that meet the IGC definition of Club Class. As in the UK,
handicaps are assigned by the national organization. One of the two
classes excludes no gliders at all, but disallows one of the tasks.
The other one is similar to the UK Club Class, with the addition of
locally popular gliders. Of the two classes, only the former has a
national championships. Here is the USA handicap list:

Competition pilots in all three countries (at least those who read
this newsgroup) seem satisfied with their local implementations of the
IGC Club Class.
