Read the lights.
Hold the right of way.

When the sun's down or the fog rolls in, a vessel's lights tell you everything — what she is, where she's headed, and who gives way. This one-page checklist keeps that answer in the cockpit, not buried in the rulebook.

• ✦Every light configuration you'll actually meet — power, sail, fishing, towing, at anchor, restricted in ability to maneuver.
• ✦Right of way at a glance — mapped directly to the lights in front of you, so the call takes seconds.
• ✦Sound & distress signals — what one prolonged blast, five short, or a red flare actually mean.
• ✦Grounded in the COLREGs & US Inland Rules (33 CFR) — wording you can trust on the water.
