How to Learn Navigation Lights and Day Shapes Without Rote Memorising

TL;DR

Open any diagram full screen and pinch to zoom, then drill the lights and shapes topic with instant grading. Questions link back to the rule text so you learn the reason, not just the picture.

Lights and shapes are visual, and trying to memorise them from a list is slow.

A better way

  1. Open a diagram and look at the arrangement first, then the description.
  2. Ask what the vessel is doing: a vessel under power, fishing, restricted in her ability to manoeuvre.
  3. Go to the lights and shapes topic and answer questions on the same ideas.
  4. Read the linked rule when you miss one.

Make the misses stick

Missed questions stay in rotation until you get them right consistently, so the confusing patterns come back.

Test yourself

Cover the caption, look at the diagram and say what it is before you read it.
