As Kirk mentioned, we were just there (on Sat. Aug 21). We had first intended on taking a mooring at 79th St. but were told by the guy on the radio
that they don't allow multihulls on their moorings. As we motored past the mooring field we observed two Cats there among the other boats but we saw that they were both anchored and not on a mooring after all. We opted to go to our Plan B which was to anchor
in the cove behind Liberty State Park. Skipper
Bob's guide says that the bay is protected from all but SE winds. This looks to be true. We however had 20-25 knots blowing right from the SE. That was not the biggest issue though. Every 10 minutes or so a fishing
boat would zoom by us about 10 feet off our bow or stern and wake the crap out of us. Only about 1 in 10 would slow down.
Wanting to visit our friends in Manhattan we took our dinghy to the dock
there and left it, walking to find a water
taxi. It is a "fast" 1 hour walk to the taxi stop! After reaching the taxi stop at the "nearby" Liberty Landing Marina, we opted not to go to Manhattan after all and just walked back to the boat. Our dinghy, which we left at the dock, was just as we had left it.
As for how man boats could anchor
there, I'm not a good judge but at least half a dozen. We were the only boat when we left to go ashore. When we arrived back there was one other boat anchored in the bay. We left the next day for Great Kills and saw no other boats attempt to anchor there.
