EXCHANGE PLACE, New Jersey (PIX11) – Seven people were injured Friday when a commuter ferry struck a pier in New Jersey around 4:30 p.m.

Investigators are trying to figure out why the New York Waterway ferry was pulling into the wrong dock when the accident happened. The ferry was traveling from Lower Manhattan when it slammed hard into a gunny pier at Exchange Place, inside of docking several blocks South at the main terminal — its usual destination.

People did fall down during the hard landing, NY Waterway spokesman Pat Smith confirmed. Seven of the 24 commuters reported minor injuries, mostly to their necks and backs.

Two crew members and five passengers, including two children, were being taken to Jersey City Medical Center for further treatment.

The cause of the hard landing and the ferry captain’s decision to dock at the wrong pier are under investigation.
