Leaks in your own exhaust system from the engine or generator can allow harmful
levels of CO to accumulate at a surprising rate. Good maintenance practices are
critical to avoid this.
There are many variables that can combine to affect the accumulation of carbon monoxide. Some of
these variables are: the presence of weather enclosures and covers, boat layout and configuration,
location of ports, hatches, windows, doors, and vents, proximity and types of structures and other boats,
wind speed and direction, speed of the boat, etc. Although it would be impossible to identify every
variable or combination of variables that may affect the accumulation of carbon monoxide, the boat
operator must remain aware at all times of the possibility of CO accumulation. The following additional
illustrations show how Carbon Monoxide Gas (CO) can accumulate in your boat while you are at the dock
or underway. Become familiar with these examples to prevent exposure to this poisonous gas.
Figure 1. Blocked hull exhaust outlets near a pier, dock,
seawall, bulkhead or any other structure can
cause excessive accumulation of Carbon
Monoxide gas with the cabin areas of your
yacht. Be certain hull exhaust outlets are not
blocked in any way.
Figure 2. Engine and generator exhaust from other vessels
alongside your yacht, while docked or anchored,
can cause excessive accumulation of Carbon
Monoxide gas within the cabin and cockpit areas
of your yacht. Be alert for exhaust from other
vessels.
Figure 3. When protective weather coverings are in place,
engine or generator exhaust from your yacht, while
docked and/or running, can cause excessive
accumulation of Carbon Monoxide gas within the
cabin and cockpit areas of your yacht. Always
provide adequate ventilation when the weather
coverings are in place and either the engine or
generator are running.
Figure 4. Engine or generator exhaust from your yacht while
underway at a slow speed can cause excessive
accumulation of Carbon Monoxide gas within the
cabin and cockpit areas of your yacht. A tail wind
can increase the accumulation. This is often
referred to as the “station wagon effect”. Always
provide adequate ventilation or increase your
speed if possible.
