We took the trek up the east river last Monday and returned south yesterday
following the rules for fair current posted here: Navigating the East River - Choosing the Right Time (Fair Current or Slack Water?) to Make the Passage
These rules appear consistent with the advice given here.
Our northbound track can be viewed in Google earth here:
Our southbound track can be viewed in Google earth here:
Northbound, we left about 30 minutes before the designated auspicious time and it took 2 hours to transit north to the Throgs Neck Bridge.
The reverse path to the Battery was about 1:45 in duration and the GPS read 10.5 kts through Hell Gate.
Please let me know if anyone finds the log useful ( or amusing).
