SAFETY-12
Engine or generator exhaust from your
yacht while underway at a slow speed
can cause excessive accumulation of
Carbon Monoxide Gas (CO) 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.
Engine or generator exhaust from your
yacht while underway and operating with
a high bow angle can cause excessive
accumulation of Carbon Monoxide Gas
(CO) within the cabin and cockpit areas
of your yacht. Always provide adequate
ventilation and redistribute the load to
lower the bow angle.
HOW TO MINIMIZE THE ACCUMULATION
OF CARBON MONOXIDE
Practice good inspection and maintenance
habits.
Be certain hull exhaust outlets are not
blocked or restricted in any way.
Be alert for exhaust gasses from other
boats.
Always provide adequate ventilation when
weather enclosures are in place and engines
or generator is running.
Do not run with a high bow angle. Use trim
tabs or redistribute the load to maintain a
low bow angle.
Orient your boat to maximize the dispersion
of CO.
Be aware of the effects of your actions on
other boats.
Be aware of the effects of the actions of
others on your boat.
Provide adequate ventilation when open
fl ame appliances are used in the cabin.
PREVENTIVE MAINTENANCE
Frequent inspections and proper mainte-
nance of the engine, generator, and exhaust
systems as well as other various areas of
your boat are critical in preventing the ac-
cumulation of carbon monoxide. It is the
owner’s responsibility to make sure that
the entire boat is inspected and maintained
against CO.
