Officials Pinpoint Reason for Ship’s Collision With the Brooklyn Bridge

A Detailed Account of the Cuauhtémoc’s Collision with the Brooklyn Bridge

On the evening of May 17, 2025, New York City bore witness to a catastrophic and highly unusual maritime accident: the Mexican Navy’s tall ship Cuauhtémoc smashed into the iconic Brooklyn Bridge, resulting in two fatalities and leaving 19 others injured. The vessel, carrying 277 cadets and crew members as part of a goodwill training mission, was navigating the East River when a sudden mechanical failure caused it to lose propulsion. Unable to clear the bridge’s span, the ship’s towering masts collapsed onto the roadway below. What follows is a comprehensive, professional overview of the incident—its sequence of events, immediate aftermath, ongoing investigation, and broader implications for maritime safety in major urban waterways.

1. Chronology of the Incident

1. Departure and Early Course

   • Around 6:30 PM, the tall ship Cuauhtémoc departed its Manhattan berth, bound for a scheduled tour of New York Harbor and the East River. Under clear skies and calm currents, the vessel steamed northward, with cadets on deck enjoying an evening training exercise.

2. Approach to the Brooklyn Bridge

   • By 8:15 PM, the ship approached the narrow corridor beneath the Brooklyn Bridge. Although it was not part of the vessel’s planned route, navigational adjustments—likely to showcase the ship against one of New York’s most famous landmarks—brought it inexplicably close to the bridge’s center span.

3. Mechanical Failure and Loss of Power

   • At approximately 8:20 PM, as the Cuauhtémoc attempted to pass under the bridge, its propulsion system suffered a sudden malfunction. Witnesses reported that the ship “went dead in the water,” losing steering and thrust simultaneously. Without engine power, the vessel began drifting with the current toward the bridge’s piers.

4. Collision and Mast Collapse

   • The ship’s main and mizzen masts—each extending well above the bridge’s clearance limit—struck the underside of the railway and pedestrian spans. Under tremendous force, the masts shattered and collapsed, sending rigging and spars crashing down onto the bridge deck and into the river. Two crew members, standing aloft when the impact occurred, tragically fell from the rigging and later succumbed to their injuries. An additional 19 individuals sustained trauma ranging from fractures and lacerations to head and spinal injuries; two remain in critical condition.

5. Emergency Response

   • Within minutes, New York City’s Emergency Medical Services, Fire Department, and NYPD converged on the scene. Floating cranes and the city’s marine unit helped stabilize the vessel and retrieve debris. Injured crew were triaged on the riverwalk and ferried to nearby hospitals. By 9:30 PM, the Brooklyn Bridge was closed to all traffic, and divers began searching the river below for any additional victims or debris.

2. Official Statements and Immediate Actions

2.1 New York City Authorities

• Police Commissioner Wilson Aramboles provided the first public account of the evening’s events, confirming that the Cuauhtémoc “strayed from its intended course” after departure from Manhattan. He attributed the collision to a sudden mechanical failure that left the ship powerless under the bridge, necessitating an emergency response to prevent further loss of life.

• Mayor Eric Adams released a statement via social media at 11:00 PM:

  “Tonight, the Mexican Navy’s training vessel Cuauhtémoc experienced a catastrophic loss of propulsion and collided with the Brooklyn Bridge. Of the 277 aboard, 19 were injured—two critically—and two crew members died of their injuries. We extend our deepest condolences to their families and commend our first responders for swiftly coordinating rescue operations. Preliminary inspections show the bridge structure itself sustained no permanent damage and will reopen once safety checks are complete.”

2.2 Mexican Government Response

• President Claudia Sheinbaum issued a message of mourning and solidarity:

  “We are profoundly saddened by the passing of two cadets aboard the Cuauhtémoc during last night’s accident in New York Harbor. Our thoughts are with their families. Under the guidance of our Navy leadership, all injured personnel are receiving the highest level of care. The Mexican Consulate in New York stands ready to assist in every way.”

• Admiral Julio Alvarado, commander of the Mexican Naval Academy, confirmed that a naval inquiry would proceed in coordination with U.S. maritime authorities, ensuring a thorough examination of the ship’s machinery and navigational protocols.

3. Eyewitness Accounts: The Human Dimension

3.1 Shoreline Observers

Local residents and tourists along the Brooklyn promenade described a scene of chaos and disbelief. Flavia Moreira, a photographer capturing sunset shots, recounted:

“I saw the ship drifting toward the bridge, and suddenly the masts hit. There was a thunderous crack, then the rigging snapped. Crew members up high were thrown off; some were hanging by ropes, swinging in the air. It was horrifying.”

3.2 Bridge Foot Traffic

Pedestrians on the bridge reported hearing a loud “boom” as the wooden spars struck the metal superstructure. Commuter Jose Ramirez remarked:

“We looked down and saw rigging and shattered pieces of mast on the roadway below. People were screaming, running away. I helped pull someone back from the edge—they were about to step off in panic.”

3.3 Onboard Reactions

Surviving cadets spoke of the sudden silence after power loss, replaced by urgent radio calls and frantic attempts to restart the engines. Petty Officer Ricardo Lozano described the moments before impact:

“We tried reversing engines, but nothing happened. The current pushed us forward faster than we could react. I grabbed hold of the mast just before it gave way. The next thing I knew, we were under water.”

4. Technical Profile: Bucolic Beauty Meets Urban Engineering

4.1 The Tall Ship Cuauhtémoc

• Specifications: 270 feet in length, three masts rising over 150 feet above the waterline, four sails per mast, steel hull with wooden decking.

• Mission Profile: Built in 1982, the Cuauhtémoc serves as Mexico’s principal sail-training ship, hosting naval cadets on voyages designed to instill seamanship, leadership, and cultural diplomacy. Over decades, she has visited more than 60 countries.

4.2 Brooklyn Bridge Clearance and Design

• Clearance Height: At high tide, vertical clearance under the bridge’s navigation spans is approximately 135 feet. The Cuauhtémoc’s unladen mast height exceeds this by 15–20 feet.

• Structural Resilience: Completed in 1883, the bridge’s truss and suspension design can withstand significant impact forces; by all initial engineering assessments, the bridge’s load-bearing capacity and integrity remain uncompromised.

5. The Ongoing Investigation
