NEW YORK (AP) — A high-speed commuter ferry that crashed into a lower Manhattan dock, injuring dozens of people, had recently undergone a major overhaul that gave it new engines and a new propulsion system, and officials are looking into whether they played any role in the morning rush hour accident.

The National Transportation Safety Board also will begin interviewing crew members of the catamaran Seastreak Wall Street on Thursday, a process NTSB board member Robert Sumwalt said would take all day.

The ferry had slowed following a routine trip across New York Bay and past the Statue of Liberty Wednesday morning when the impact took place, hurling scores of people to the deck or into the walls. Around 70 were hurt, 11 seriously.
