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.
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.
