Sag Harbor-NYC-Atlantic City
Well...you can do that on a good forecast but I''d make DARN sure you''re fuel and filter /engine is in great shape. Often with a new boat there are lots of little foul things growing in the diesel and this tends to get stirred up at sea which would not make getting to AC very easy! If you have confidence in the fuel system then the trip is not difficult and saves a lot of time.
If you tak the Sound route...suggest stopping in Manhasset Bay before going under the Throgs Neck and Hell''s Gate. From there you can time the tide nicely and get a nice run down to Sandy Hook for your next anchorage. Good luck...GB
