Liberty Landing Ferry operates between the World Financial Center in NYC and Jersey City, NJ. In New Jersey, the ferry makes stops at Liberty Landing Marina in Liberty State Park and Warren Street before returning to the World Financial Center. New York Waterway runs a number of routes between New Jersey and Manhattan.
Walk Street
Depends where in Jersey, there are few of them that will take you near Pier 17 the closest one will be Walls St.
I think the seastreak travels from new jersey.
Not at pier 17.
Pier 17 is on East River at Seaport by Brooklyn Bridge. No ferry service from NJ unless you walk from aforementioned stops in Lower Manhattan. It would be about 15 minutes
Not to pier 17
Sorry I don't know any thing about ferries from Jersey
