COLREG lights quiz: what ship is this?

This is what the night watch really looks like: darkness and a few lights. We show you the night view of a vessel from a random bearing, and you name her type. The clues are the pattern and colours of the lights, and the lights you do NOT see. New to the lights? Start with the COLREG lights course and the interactive trainer, then come back.

All graphics are generated from light positions in metres per COLREG Annex I. Verified by a Master Mariner. Free, and it stays free: safety knowledge never goes behind a paywall here.
