For those of us with sticks-and-rags (yachts with a mast) try avoiding playing MIddle Harbour Bridge Limbo (so taking care to note the Spit Bridge opening times)..
We plan to head up into the upper arms of Middle Harbour and stay overnight in either Sugarloaf or Bantry Bay, surrounded by Garigal National Park. Lets hope for a dry weekend.
Chat with boat owners before the event (the social meeting is the Tuesday before), and see if you can finagle a bunk for the night.
Kayak access is another option, with several places you can put in (like Roseville bridge) or rent one from The Spit
