Good stuff! My thoughts about racing are put down at
www.seabreeze.com.au/info/racing.asp . It's awesome fun.
I reckon the $20 is good value for the opportunity to pit your skills against others in a controlled racing environment. i.e. WWA volunteers set up buoys (need a boat), provide controlled starts, are properly officiated, people scoring, trophies, etc...
PLUS, you'll be racing against some of the better sailors, so there's a huge learning curve to be had. Coming last is a great motivator to improve your sailing skills, which in turn brings more fun


Have fun .. Lozza
