I am planning to have this weekend up there. My options are RMYC at Broken Bay $55 per night for a berth. RPAYC at Newport $70 per night for a berth. Pick up a mooring. Anchor.
Hi up to Refuge or Jerusalem Bay or Castle Lagoon. Much better. If Pittwater alongside is a must go to the marina below the Newport Arms or the RMYC for a good feed and a few drinks.
A berth is okay after few day in the wild, but I vote for Refuge Bay, nice to wake up under waterfall at the end of the Bay. Moorings a plenty if you don't like anchoring. You can nip over to Patonga for lunch the next day, the pub rocks there! cheers Richard
