What should a vessel do if a tow is being overtaken and the overtaking vessel does not give way?

When a vessel is being overtaken and the overtaking vessel does not give way, it is crucial for the overtaken vessel to take action to avoid a collision. This aligns with the fundamental principles of navigation and seamanship, which aim to ensure safety on the water.

The rules of the road, specifically in the context of navigation, dictate that if there is an imminent risk of collision, the vessel that is overtaken should maneuver to prevent such an incident. This could involve altering course or speed as necessary. The priority is to avoid an accident rather than waiting for the overtaking vessel to comply with give-way rules, which may not always happen as expected.

The other options, while they may seem reasonable in different scenarios, do not address the immediate need for action to ensure safety. For instance, signaling with a long blast may alert others to a potential issue but does not actively prevent a collision. Maintaining speed could inadvertently lead to a collision if the overtaking vessel does not change their course. Reporting to authorities might be necessary after a collision, but it does not prevent an accident from occurring in the first place. Therefore, taking action to avoid collision is the most appropriate and responsible course of action in this scenario.
