Module 10 - Chartwork
Advanced Scenario Check
Decision pressure: The tidal gate creates a latest safe time, so a slow correction can invalidate the whole passage plan.
Advanced trap: Solving the first-hour vector correctly but failing to update the plan when the fix disproves the assumption.
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. |
| What do you brief? | Everyone knows. | Give short crew instructions and confirm understanding. |
Key points
- Apply Course shaping along a coastal or offshore passage 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.
