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.
