• Be aware that mooring and anchoring in an area where other boats’
engines or generators are running may put your boat in an atmosphere
containing CO, even if your boat’s engines and generator are not run-
ning.
• Keep the engine room hatch closed when operating the engines and
generator.
• Be aware that exterior enclosures can create air flows that draw in and
trap CO in the enclosed areas. Provide adequate ventilation to these
areas.
• Do not occupy aft lounging areas, including the boarding platform, or
swim near the engine or generator exhaust outlets while the engines or
generator are running.
• Because CO production is greater when the engines are cold, minimize
the time spent getting underway.
• Avoid backdrafting. Backdrafting occurs when air moving past the boat
creates a low pressure or suction area near the stern. This low pressure
area can draw CO into the boat’s cabin and enclosed exterior areas.
Under certain speed and operating conditions, the low pressure area
may form in other areas of the boat and permit CO to enter through
openings that are not near the stern.
To avoid backdrafting:
- Maintain the proper trim angle; avoid a high bow angle.
- Distribute the boat’s load evenly.
- Do not operate the boat at slow speeds, especially with a following
wind.
- Provide adequate ventilation; make sure the air flow is moving from
forward to aft inside the cabin and enclosed exterior areas.
• Have a trained marine technician inspect the boat’s exhaust systems
whenever the boat is in for service or if you notice a change in the
sound of an engine or the generator.
• Maintain the propulsion and generator engines to optimize their effi-
ciency; this in turn reduces CO emissions.
For additional information on carbon monoxide as it relates to boating,
please contact marine organizations that produce safety publications.
