I have done this passage
Chesapeake City is definitely a nice and secure anchorage. I have always anchored here.
It is an easy day to the Cohansey if the weather
and tides aren't favorable, or a longer day to Cape May. I have anchored several times in the Cohansey about 3/4 mi in, around the first hard bend to the left. Leave plenty of chain out .... strong currents. Also, put the screens in! Lots of greenheads (man-eating mosquitos)!
In Cape May, you have to go into the harbor to have a secure anchorage. Holding is only fair, so beware. Most people anchor near the Coast Guard Station.
Atlantic City Inlet is not bad in most weather. You can anchor just before the bridge on the port side near Harrah's, or take the small creek on the starboard side just before the bridge, Rum
Point, and there is a nice anchorage. Stay to port through the opening! Watch your chart.
I sailed an IP 350 out of Barnegat Inlet for many years, but not since 2018. It's ok with benign conditions, but don't try to run the inlet when the 3 knot
tide is running out and the wind
is blowing anywhere from the east! You'll have breakers and it will suck!!! There's a nice anchorage when you bear to port at the lighthouse towards the town of Barnegat Light.
Atlantic City to the NY area is a good 75 mi, a lonnnng day, or an overnight. Barnegat is much easier.
I have anchored west of Sandy Hook (ok in settled weather, but the ferries to Atlantic Highland have mean wakes!), Great Kills on Staten Island (not much room to anchor, but lots of commercial
facilities), and Coney Island Creek (easy entrance, great location by the Verrazona Bridge, but you have to ignore the "neighborhood". I didn't worry much, since there was a 1/4 mi of water
The East River is fun if you are riding the 5 knot
current! Read your chart carefully. I usually hug the Brooklyn
shore to avoid the ferries and shipping
A few hours up is Manhasset Harbor, which had 2 nights of free stay on their moorings a few years ago, and plenty of room to anchor. There is a water
taxi, and a supermarket and restaurants near the harbor.
