Question 1

You are in a crossing situation as stand-on vessel. The give-way vessel shows slight alteration but CPA remains unsafe. What is the BEST immediate action?

Accepted Answer

Take decisive avoiding action by altering course to starboard or reducing speed.. Rule 17 allows early action | Slight alteration insufficient | Avoid port | Rule 2 applies if risk remains.

Question 2

The vessel continues to approach with minimal change in bearing. What principle now applies MOST strongly?

Accepted Answer

Rule 2 requires action to avoid danger. Rule 2 overrides | Avoid immediate danger regardless of role.

Question 3

After taking action, what confirms that your manoeuvre was effective?

Accepted Answer

CPA increases and the bearing shows a clear change. Effective action = increasing CPA + clear bearing change.
