Module 12 - Visual Aids to Navigation
Advanced Scenario Check
Decision pressure: The mark may be close to a danger, so a quick but uncertain identification is not enough.
Advanced trap: Matching one flash pattern and ignoring the charted context or possible identification error.
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.
The screen says so.
Yachtmaster answer: Cross-check independent sources and name any conflict.
It should be fine.
Yachtmaster answer: State depth, time, sea room, weather, crew, or traffic margin.
I will see later.
Yachtmaster answer: Name a trigger: time, position, visibility, crew state, or equipment failure.
Everyone knows.
Yachtmaster answer: Give short crew instructions and confirm understanding.
