Module 11 - Tides & Tidal Streams
Yachtmaster Offshore Standard
Tides & Tidal Streams at Yachtmaster level is not just recall. The answer has to show command judgement, evidence quality, margin, and a fallback if the first plan stops being safe.
Scenario: A secondary-port calculation gives enough depth on paper, but low pressure, wind setup, and a late arrival reduce the margin.
Examiner expectation: Show the calculation, state the assumptions, add safety margin, and name the fallback if the actual tide differs.
Key points
- State the evidence you trust and the evidence you distrust.
- Name the margin that makes the plan defensible.
- Choose the first action that preserves safe options.
- Explain the contingency before the situation becomes forced.
