Module 8 - Drawing Instruments
Advanced Scenario Check
Decision pressure: Under time pressure, untidy plotting becomes a navigation risk rather than just an exam presentation issue.
Advanced trap: Getting a plausible line on the chart but leaving no labelled evidence of method, time, or units.
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.

| What is your evidence? | The screen says so. | Cross-check independent sources and name any conflict. |
| What is your margin? | It should be fine. | State depth, time, sea room, weather, crew, or traffic margin. |
| What changes the plan? | I will see later. | Name a trigger: time, position, visibility, crew state, or equipment failure. |

Key points
- Apply Use of parallel rulers, dividers, and proprietary plotting instruments 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.
