Module 5 - COLREGs

Advanced Scenario Check

Decision pressure: A small course alteration may look neat on paper but be invisible to the other vessel.

Advanced trap: Quoting a stand-on/give-way rule while ignoring continuing responsibility and restricted evidence.

A strong Yachtmaster answer says what you would do now, what you would monitor next, and what would make you change the plan. It should sound like an instruction a crew could follow, not a paragraph copied from a textbook.

What is your evidence?

The screen says so.

Yachtmaster answer: Cross-check independent sources and name any conflict.

What is your margin?

It should be fine.

Yachtmaster answer: State depth, time, sea room, weather, crew, or traffic margin.

What changes the plan?

I will see later.

Yachtmaster answer: Name a trigger: time, position, visibility, crew state, or equipment failure.

What do you brief?

Everyone knows.

Yachtmaster answer: Give short crew instructions and confirm understanding.

Key points

  • Apply Steering and sailing rules (Rules 5, 7, 8, 9, 10, 12–19) to a changed real-world situation.
  • Separate fact, estimate, and assumption.
  • Show what you would brief to helm, navigator, lookout, or deck crew.
  • Make the conservative option visible before defending any higher-risk choice.
