Navigation Lights: Rules and Recognition
The lights are a language with a fixed vocabulary. Learn the arcs, the ranges and the patterns, and a distant vessel tells you what she is and where she is going.
Rules & Regulations
Most collisions are not accidents of fate but failures to apply rules every officer is supposed to know cold. This is the law of the sea made practical: the COLREGs and right of way, SOLAS, MARPOL and STCW, and the flag and port state regimes that decide whether your ship sails or stays alongside.
COLREGs: The Rules of the Road at Sea
No lanes, no traffic lights, just one ruleset that decides who gives way and who holds course. A working guide to the COLREGs and the judgment behind them.
