Normally you must transit west of Roosevelt Island. There is a lift bridge on on the east channel. The lift bridge will not open if the west channel is open and you will not clear the bridge unless it is lifted.
The west channel is closed based upon security threats to the UN. This may or may not be in the Notice to Mariners. When the west channel is closed security forces are highly visible at both the north and south ends of Roosevelt Island. They will hail you on Ch. 16. and direct you into the east channel. Failure to respond ensures an imminent opportunity to see CG machine guns up close.
If you are directed to the east channel you will need to hail the lift bridge operator. The bridge opens on demand but there is a thirthy minute wait as they go through their signal sequence.
Westbound you will face strong adverse currents once you round the Battery. Eastbound try to time your rounding so that you enter the East River just as the current turns northbound; you'll have a favorable current down the Hudson and out the Sound all the way to Stamford. Keep your head up as you round the battery for brisk ferry traffic.
