This question will resolve to all the answers that are contributing factors of why the boat hit the bridge. As long as there's a reasonable causal connection, it counts - eg "failure to properly follow up on inspections" would count, so long as the followup could have plausibly averted the collision.

According to the NYTimes, what we know so far:

Why did the ship hit the bridge?

It is not known, and the National Transportation Safety Board said it is investigating. The 985-foot-long cargo vessel, called The Dali, was leaving the Port of Baltimore when it lost power and issued a mayday call just before hitting a critical component of the bridge, known as a pylon or pier. Radio traffic from emergency workers suggested that the crew was struggling to steer the ship, according to audio published by Broadcastify. Most of the lights of the ship went dark abruptly, just over two minutes before the ship hit the bridge. Baltimore harbor pilots were directing the ship at the time of the crash, as is customary when vessels enter ports or canals, according to a joint statement from the ship’s owner and manager. Governor Moore said the bridge was fully up to code, and that the collapse did not appear to be the result of a structural issue.

Feel free to add your own answers. I will moderate and N/A any that are obviously false/true and don't add value.

I'll only bet to set some initial values.
