I went to a work event at the Willy Wall and tried to convince the launch captain to drop me off in JC. He basically said the ferry people would sink him with torpedoes if he tried to use their dock.

Nytimes: the Admiral?s Launch, picks up visitors at the marina and for a $18 fee shuttles them past water taxis and ferries to a landing on the barge (that's a bar)

Part of the greatness comes from the way you approach the Willy Wall. A vintage motorboat, the Admiral?s Launch, picks up visitors at the marina and for a $18 fee shuttles them past water taxis and ferries to a landing on the barge. (That is, until it reaches its 150-person capacity.) The launch is driven by a uniformed old salt named Captain Billy. He is a chivalrous and grizzled man, recently out of Florida, and gives the air of having spent last night inside a bottle of Haitian rum.

the "Willy Wall" is:
the Honorable William Wall, a waterborne watering hole moored during the warmer months on the never-ending chop of New York Harbor. ?It?s pretty basic,? Mr. Claus, 60, suggested, looking at the skyline, a white wine in his hand. ?Sailors like to drink.?

The Willy Wall, as the cognoscenti call it, is ? officially ? the clubhouse for the Manhattan Sailing Club, an organization that since 1987 has catered to the oceangoing urges of New York City?s nautical community. A two-story barge christened with the name of a Civil War congressman, it is a sort of floating roadhouse where urban mariners and members of the public can gather from May until October and, as seamen like to say, get three sheets to the wind.

BTW -- It is a BYOF -- bring your own food!
