Manual contents

Buoyage brings together visible cues, documents and context. Begin by recognising families and the attributes described by a source: colour, shape, topmark and light where present. The manual separates observation, identification and application, explaining why region and publication reference accompany a reading. Figures are original schematics with no real harbours or routes. Specific mark and practical interpretation chapters become available as their content and review are ready. A buoy photograph may prompt curiosity; learning reveals which questions remain.

Colour, shape, topmark and light help describe a mark; they are not a ready-made route.
