The marina has over 250 slips for vessels up to 120 feet (37 m) in length, a boat and kayak launch, and a ferry landing.
The ferry landing is currently used by SeaStreak, which provides service to Highlands, New Jersey for selected New York Mets games.
A free ferry operated by New York Water Taxi provides service between Pier 11/Wall Street and the East 34th Street Ferry Landing in Manhattan and the World's Fair Marina, for the US Open and before Mets games.
The marina's administration building constructed for the 1964 World's Fair now houses the New York City Department of Parks & Recreation Marine Division office and the World's Fair Marina Restaurant & Banquet Hall.
Robert Moses had the marina redesigned and expanded to accommodate 800 boats for the 1964 New York World's Fair, which was held in the same location.
