vated whenever the cabin DC breaker panel is energized. Some of these devices require a warm
up period. Refer to the manufacturer's instructions.
Always make sure the Cabin DC Breaker Panel and the carbon monoxide detector are
activated by the house battery switch whenever the cabin is occupied.
Carbon monoxide (CO), a by-product of combustion, is invisible, tasteless, odorless, and is
produced by all engines, heating and cooking appliances. It exists wherever fuels are burned to
generate power or heat. The most common sources of CO on boats are gasoline engines and
auxiliary generators and propane or butane stoves. These produce large amounts of CO and
should never be operated while sleeping. Also be aware that, in some situations, CO from a
generator or an engine being operated in nearby boats can enter your boat and present a hazard
for you and your passengers. High concentrations of CO can be fatal within minutes. Many cases
of carbon monoxide poisoning indicate that while victims are aware they are not well, they
become so disoriented they are unable to save themselves by either exiting the area or calling for
help. Also, young children, elderly persons, and pets may be the first affected.
Drug or alcohol use increases the effect of CO exposure. Individuals with cardiac or respiratory
conditions are very susceptible to the dangers of carbon monoxide. CO poisoning is especially
dangerous during sleep when victims are unaware of any side effects.
Low levels of carbon monoxide over an extended period of time can be just as lethal as high doses
over a short period. Therefore, low levels of carbon monoxide can cause the alarm to sound
before the occupants of the boat notice any symptoms of carbon monoxide poisoning. CO
detectors are very reliable and rarely sound false alarms. If the alarm sounds, always assume the
hazard is real and move persons who have been exposed to carbon monoxide into fresh air
immediately. Never disable the CO detector because you think the alarm may be false. Always
contact the detector manufacturer or your local fire department for assistance in finding and
correcting the situation.
In certain situations, boats can have a problem due to the “station wagon effect” where engine
exhaust fumes are captured in the vessel by the vacuum created by a rear opening or installed
canvas while underway. Boats that are underway should close all aft portholes and open a
forward facing hatch which may lend to pressurize the living spaces within the boat. Sleeping,
particularly in aft cabins, should not be permitted while underway. Occupants of the “bridge”
also should maintain proper ventilation by opening a forward window or windshield vents to
drive fumes away from the occupants. Extreme caution must be taken while at anchor or in a slip
and an auxiliary power generator is operating. Wind still nights can easily allow fumes to enter
the boat. Inspect the exhaust systems of propulsion and the auxiliary generators, if installed,
frequently for possible leaks. High concentrations of CO in your boat may originate from an
adjacent boat. Exhaust fumes from nearby boats may enter your boat through open hatches or
windows.
Symptoms of carbon monoxide poisoning are dizziness, ears ringing, headaches, tightness of
chest or hyperventilation, drowsiness, fatigue or weakness, inattention or confusion, lack of
