What is the immediate action to take after experiencing a collision?

The immediate action to take after experiencing a collision is to pass the word over the 1MC and sound the collision alarm. This is crucial because timely communication is vital in emergencies. Sounding the collision alarm alerts all personnel on board to the situation, prompting them to take necessary precautions and prepare for potential actions such as damage control, evacuation, or securing the ship.

Additionally, passing the word over the 1MC ensures that everyone on board is informed of the collision immediately, which is essential for coordinating an effective response. This action helps in managing the situation efficiently by mobilizing the crew and initiating emergency procedures as necessary.

While actions such as contacting the naval command center, checking for injuries, and logging prior positions are important, they should follow the immediate alerting of the crew. Prioritizing the sounding of the alarm ensures that all personnel are aware of the situation and ready to respond.
