"A commuter ferry had a hard landing when it pulled into a Lower Manhattan pier, injuring at least 53 people Monday morning," WABC-TV is reporting .

At least one person suffered a serious head injury, according to The Associated Press.

The New York Post writes that "the craft's front, starboard side appeared to sustain significant damage in the crash — though the ferry was stable and secured to the dock." The accident happened around 8:45 a.m. ET. The Post says more than 300 people may have been on board.

New York 1 says "a representative from Seastreak, the ferry's operator, says they believe the 'Seastreak Wall Street' departed from its Highlands [N.J.] pier at 8 a.m."

The ferry was traveling at between 11.5 and 13.8 miles per hour (10 to 12 knots) when it hit a loading barge and another dock, says New York 1 , citing Department of Transportation Commissioner Janette Sadik-Khan.

The station adds that 326 passengers were on board, along with a crew of five.
