Figure 4.3. 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 boat. Be cer-
tain hull exhaust outlets are not blocked in any way.
Figure 4.4. Engine and generator exhaust from other vessels along-
side your boat, while docked or anchored, can cause excessive
accumulation of Carbon Monoxide gas within the cabin and cockpit
areas of your boat. Be alert for exhaust from other vessels.
Figure 4.5. Engine or generator exhaust from your boat while under-
way and operating with a high bow angle can cause excessive accu-
mulation of Carbon Monoxide gas within the cabin and cockpit areas
of your boat. Always provide adequate ventilation and redistribute
the load to lower the boat angle.
Figure 4.6. When protective weather coverings are in place, engine
or generator exhaust from your boat, while docked and/or running,
can cause excessive accumulation of Carbon Monoxide gas within
the cabin and cockpit areas of your boat. Always provide adequate
ventilation when the weather coverings are in place and either the
engine or generator are running.
Figure 4.7. While underway or drifting
