If someone else strikes your vessel and it’s not your fault, what is the first thing you should do?

When another vessel strikes yours and it's not your fault, the first thing to do is to look behind you. This action is crucial as it allows you to assess the situation safely and ensure that there are no additional hazards coming from behind that could put you or your passengers in further danger. By checking your surroundings, you can make informed decisions about how to proceed, such as whether it's safe to remain where you are or if you need to maneuver your vessel out of harm’s way.

Additionally, looking behind you helps you stay aware of the other vessel's movements and the overall state of the water around your boat, which is vital before taking any further steps, such as assessing damages or calling for help. Understanding the immediate environment is the first step in safely managing the aftermath of a collision.
