The investigation into how the accident happened is still under way.
"This is the start of a long process," Michael Graham of the National Transportation Safety Board (NTSB) said during a briefing on Monday. "We will not be drawing any conclusions, we will not speculate."
Mr Graham said there was "no significant structural damage" to the load-bearing elements of the Brooklyn Bridge.
His colleague, Brian Young, provided a preliminary timeline of events on the night of 17 May.
- At 20:20 local time (00:20 GMT), the Cuauhtémoc backed away from Manhattan's Pier 17 with the assistance of a tug boat. It intended to sail south on the East River before heading out to sea, Mr Young said
- After departing the pier, the ship's astern (backwards) motion and speed increased up to 6 knots
- At 20:24 a radio broadcast was sounded requesting assistance from other tugboats in the area. It was followed by two other requests
- At 20:24 and 45 seconds, the Cuauhtémoc's mast struck the underside of the bridge
- At 20:27 the ship came to a stop
- By 20:30, New York City police and firefighters arrived on the scene
New York police officials previously said it appeared that the Cuauhtémoc had lost power as it was leaving New York Harbour and was dragged towards Brooklyn Bridge by the current.
Its three masts, measuring more than 48m, hit the base of the bridge, which -according to the New York transport department's website – only has a clearance of 41.1m.
All three masts collapsed and video footage taken by bystanders shows some of the crew members dangling from the yards and sails.
Mr Graham said that his team would consider the status of the engine during their investigation.
"On behalf of the NTSB, I wish to express my most sincere condolences to the families and loved ones of those who lost their lives in this terrible tragedy," he said.
Mexico's Navy Secretary Raymundo Pedro Morales Ángeles said in a statement the results of any investigation would be followed with "total transparency and responsibility".
The Cuauhtémoc left Acapulco, Mexico, on 6 April on a tour that included stops in New York and Aberdeen, Scotland, for the city's Tall Ships race in July.
