Poor Ventilation

Under certain running 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 open area of a stationary boat that contains
or is near a running engine may be exposed to a hazardous level of carbon monoxide.
