For anyone thinking of racing at Noosa this Saturday:
I just got an email back from the race organiser and unfortunately they can't offer a total downwind race as there is nowhere to launch or come ashore if they run a downwind race, so the short course will be a triangle course inside the bay at Noosa, and the long course will be run out around the headland, down to Sunrise Beach and back. Here are the maps of the 2 courses.
