Module 9 - Compass
Yachtmaster revision outcome
Use Three Norths as an applied Yachtmaster decision, not just a definition list. The course outcome is that a Yachtmaster candidate can recognise the situation, choose a defensible action, and explain the check that supports it.
A paid revision product needs to build exam recall and cockpit judgement at the same time. Work this module by saying the cue, the risk, the calculation or rule if there is one, and the skipper action you would take before moving on.
What tells me this is a Three Norths problem?
Why it matters: Stops keyword guessing and forces context.
Which rule, calculation, symbol, or procedure changes my decision?
Why it matters: Turns memory into a skipper action.
What chart, almanac, forecast, instrument, or crew factor could change the answer?
Why it matters: Builds margin and avoids brittle exam-only recall.
What would I do now, and what would make me delay or stop?
Why it matters: Connects the course to Yachtmaster-level command judgement.

Key points
- Recognition cue: True North — geographic north (charts are drawn to true north).
- Decision cue: Magnetic North — where a compass needle naturally points.
- Safety cue: Compass North — where YOUR boat's compass points (includes deviation).
- Revision standard: answer in plain English, then state the source or cross-check you would use on board.
