A high-speed ferry loaded with hundreds of commuters from New Jersey slammed into a dock in lower Manhattan during the morning rush hour, injuring dozens of people. The Seastreak ferry hit the dock pulling into Pier 11 near the South Street Seaport just before 9 a.m., opening a large gash on the starboard side of the bow. At least 81 people suffered injuries, 10 were serious, but as of Wednesday night only three people remained hospitalized with one in critical condition.
