Poor Ventilation

Under certain 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 an operating engine may be exposed to
a hazardous level of carbon monoxide.
