They move an unbelievable number of people through the boarding area in a very short period of time. Impossibly short. I bet it borders on fastest possible.
There is a wide range of ferries ... From the swanky Molinari class to the ultra crappy Andrea dorea class.
A huge percentage of people on our ferries have "recircUlated" (gotten back on)- maybe as many as 15%.
SI terminal is better than manhattan.
My favorite ferry seat iS center bow on the bridge deck of a Molinari class boat.
Security truly could not care less if you ride for 24 hours straight.
