Workers are, at this time, preparing the Haverstraw Ferry Landing for New York Water Taxi service, which is expected to begin in August. Construction crews have closed the northern side of the ferry parking lot, while they drive pilings in the water and add docks and ramps. The New York Water Taxi slip will be located on the northern side of the Ferry Landing and just south of the Haverstraw Elks Club. The New York Waterway ferry slip will remain where it is. Docks for recreational boating are also being installed in the water gap south of the Elks Club. Work on a new ferry pier at the base of Main Street in the Village of Haverstraw is expected to begin in Spring 2008. The two ferry operations will move to main street, once work there is completed; this may happen as early as Fall 2008.

The docks are open to anyone who is willing to pay for a slip. Of course, “Harbors” residents have priority, but there are many slips still available.
Another update, confirming the new service will begin on August 1st! http://www.thejournalnews.com/apps/pbcs.dll/article?AID=/20070714/NEWS01/707140356
The marina is called “The Marina at Admiral’s Cove” it’s a tacky name, but a really beautiful marina! The docks are amazing
