US Open Tennis Ferry; it's free but you need to make a res

As I read it in Crains (including the typo):

Tennis fans can catch a free ferry ride to the U.S. Open from Aug. 31 to Sept. 6, thanks to a sponsorship deal between New York Water Taxi and Coca-Cola.
Ferries will leave from the East River at East 35th Street and arrive at the World’s Fair Marina, where shuttle buses will spare passengers a 20-minute walk to Arthur Asche Stadium. New York Water Taxi will make a number of round trips, starting at 9:30 a.m. from Manhattan and leaving Flushing, Queens, as late as 11:45 p.m. Reservations on the 149-passenger vessels are required and can be made online via the ferry company’s Web site.
Coca-Cola is paying to “wrap” one of the boats, which will feature the logo of its sports drink, Powerade Zero, as well as an image of tennis great Venus Williams.
