There are a couple of inlets deep and wide enough that you could easily use for a stopover make but not sure if they are useable in strong onshore winds.
However if you anchor
behind Sandy Hook it is only about 120 nm to Cape May which is an easy overnighter. Just check the weather
before you leave to make sure you have a good window.
You aren't considering the trip this time of year are you? It is a bit cold and the Nor'easters are starting to roll in.
