A is the main carpark. You'll almost always get a park here, especially in winter. It's free for ages, 12 hours i think. Bit of a trek with all your rigged gear to...
B is the launch point. If you're lucky you'll get a carpark right there. There are about 4.
C is the alternate park and launch point. Parking is much harder but a better spot.
Being a westerly it's going to be gusty as hell but it's not a bad spot in a westerly. Clean chop compared to other directions. Kinda cool to be looking upwind to the Opera House when you are out in the harbour some more. Perhaps worth it for that unique experience alone.
LOOK OUT FOR OYSTERS at launch point B. I have scars.
