I would refer to the attack Prein made on Scapa Flow, as a reference. A pre-war knowledge of the harbor, by a member of the crew, would be most helpful.
A knowledge of the Hudson River and tides (high and low) would help.
Depending on the date in 1942, in your novel, black-out conditions may have not been enforced by the government. Lights of the city are helpful in navigation.
Following a freighter's wake could be used to enter the harbor.
The time of year also has an effect on navigation. Winter storms provide a chop to the waves, concealing periscope observations. A calm summer day, with the Hudson River almost as smooth as glass, could reveal a periscope easier.
In a practical sense, a Captain may have better luck, by staying off shore from the harbor and use the city lights as a backdrop illumination for passing freighters.
Probst!
