Re: Planning a trip up the East River, Timing?
Check out this site Deepzoom.com you can go to any date that you want and see what the tide/current is going to be doing.
Having done the East river several times in a 36' person and my own 33 Newport I have always found it best to pay attention to the current and plan your trip to ride the ebb/flood up or down. It will only be rough if you have an opposing wind.
Enjoy your trip. IMHO that is the only way to see NYC - from the deck of your sailboat.
