Unfortunately, facilities in New York are not very good. Those on the Hudson River tend to be VERY rough compared to what moat are used to. If you do stay on the Hudson at most facilities (Libery Landing and Liberty Marina are two exceptions as they are pretty calm albeit a bit of a trip to get across the river) I highly recommend doubling your lines and using Shockles to reduce the shock load from the ferries, barges, etc. Sheepshead Bay in Brooklyn is often overlooked as a place to stay. There are several yacht clubs and if you contact them in advance you may work out a reciprocal arrangement if you are a yacht club member. They also have the advantage of being serviced by the NY subway system. The B train runs express into Manhattan and is only about a 45 minute trip. Most marinas on the New Jersey side are a thirty minute to forty five minute trip. There are ferries however they often end in the early evening. You’ll have to check the individual ferry schedules to be safe.
