Passengers who had boarded the 141-foot Seastreak Wall Street in Atlantic Highlands, New Jersey, and were queued up to disembark in New York, were thrown to its deck by the impact of the hard landing.
People were thrown through the air as the commuter ferry slammed into a pier, according to passenger Brett Cebulash, 50, an attorney who regularly rides the ferry, which has a monthly commuting cost of $655 (£409).

The boat was travelling on calm waters at between 10 to 12 knots, or about 11.5 to 14 miles per hour when it crashed into the pier, New York City Department of Transportation Commissioner Janette Sadik-Khan said.
The National Transportation Safety Board tweeted that its investigators were gathering information about the cause of the crash.
A construction worker, who asked not to be named, told Reuters he was working nearby when he saw the 400-passenger ferry slam into the pier.
The boat was backing up and hit something and that's when everything went crazy.
