Don’t swim or sit near the swim platform when any engine is running. Don’t hold on to the swim platform while the boat is underway (no “Teak Surfing”)

Don’t moor next to another boat whose engine is running. Don’t confuse carbon monoxide poisoning with seasickness or intoxication.

Do immediately move the person to fresh air, investigate the cause and take corrective action if someone on board complains of irritated eyes, headache, nausea, weakness or dizziness. Seek medical attention if necessary.

Do make sure generators are properly ventilated, and keep engine and generator exhausts clear. Do always shut off engine and generator when moored, anchored or standing still.

Do be aware that the station wagon effect, or back drafting, can cause carbon monoxide to accumulate inside the cabin, cockpit and bridge when the boat is underway, moving at a slow speed or idling.

Do keep your boat’s engine well-maintained, and regularly check to make sure carbon monoxide detectors in the cabin are working properly.

Do always wear a properly fitted life jacket while in or around water.
