Module 10 - Chartwork

Yachtmaster Offshore Standard

Chartwork 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 three-hour passage leg has changing tidal streams, leeway, a mid-leg fix, and a tidal gate at the far end.

Examiner expectation: Build a CTS or amended plan that accounts for changing tide, uncertainty, and the latest reliable fix.

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.
