Under certain running and/or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits with
insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your
boat.
Although the occurrence is rare, on a very calm day, swimmers and passengers in an unclosed area of a
stationary boat that contains or is near a running engine may be exposed to a hazardous level of carbon
monoxide.
2 Examples of poor ventilation while boat is stationary:
A Running the engine when the boat is moored in a confined space.
B Mooring close to another boat that has its engine running.
3 Examples of poor ventilation while boat is moving:
A Running the boat with the trim angle of the bow too high.
B Running the boat with no forward hatches open (station wagon effect).
