Sport Class competitions have taken off especially in Mexico (Valle de Brovo and
San Marcos) and Guatemala. You'll also find them in Russia, France, the USA, and
Kazahstan, as well as other location.

Sport class is now a legitimate class with lots of participation. We haven't
attempted to obtain USHPA and CIVL sanctioning previously for the Green Swamp
Sport Klassic (although we do so for our other national series meets which all
contain sport class), but it looks like we shall do so in the future.

Sarah Weaver, US pilot, is the highest ranked female in Sport Class.

Unfortunately, Sport Class is not ranked in the US, although the results of US
CIVL sanctioned competitions are sent to CIVL.

It wasn't that long ago that one meet organizer in the US didn't allow sport
class in her towing meets.
