Pick up a copy of Eldridges Tide & Piloting http://us.st11.yimg.com/us.st.yimg.c...v_1972_8124412
Sorry sailnet but I could not find this on your site.
This will be a good reference for you in order to time your passage around The Battery in NY Harbor and up the East River thru Hells Gate. You should look at it as a total exprience going thru the Battery and up the East River as it truely is. Best to be at HG around slack tide so there is no push either way. Next best might be a slight flood tide (tide on the nose but you want to check Eldrich as I have forgotten weather flood tide is in or out at HG ) so as not to get going too fast. Try to avoid extreme tides in either direction as you will feel a bit out of control and won't enjoy it as much. You want to be able to look around an take in everything as there is a lot going on...especially if you time it in the morning around Rush hour. Don't be intimidated..........take your time and have fun
