My wife and I moored over night two weeks ago on one of the Town of North Hempstead's moorings as mentioned earlier. There are a half dozen or so, yellow
mooring balls pretty much right where Activecaptian puts them. #7 has
lost it's pennant but we took it anyway as it was the last open one for the day. We had to McGyver it a little by bending on heavy shackle and heavy
dock line. The town's very friendly
water taxi is $4 per passenger one way and they run until about 11pm. They
monitor 9/71.
I would check North Minneford, it looks like they have several open/transient moorings available.
There is a laundromat, 2 grocery stores and 2 marine/hardware stores on the island. The City Island Yacht Sales dock has Gas/Diesel and pumpout. 8:30-4:30 Mon-Sat.
There's a 15 min. bus ride to a subway station if you want to dip into the big city too.
