I am all in favor of sponsorship, promoting the sport, the sport as a better recreational activity vs jetski's etc...
(and i really dislike sailing through exhaust, sailing near boats who don't understand sailing nor right of way, and the noise of motors)...

but i dont think you can call our sport "green".. (even though we are "greener" than jetski's) with the amount of petro-chemicals used in the production of our boats/lines/blocks/sports clothing.... etc

Unless we go back to hemp lines, and wooden boats .. we are a part of the petro-industrial manufacturing world.
