N. Cabin Appliances
Figure B13: Operating at Slow Speed
with Following Wind
Boats having fuel burning appliances in accommo-
dation areas should be provided with adequate
ventilation and the appliance should be maintained
to function properly.
. Be aware that cockpit and deck drains can be a
source of CO ingress into boats, especially boats
with cockpit or decks enclosed with canvas or
permanent boat structures.
O. Air Conditioning
L. Accumulation of Exhaust Gases-
Lack of system maintenance may cause CO to be
brought into the air-conditioned spaces by the air
conditioner. Please refer to the air conditioner
manufacturer’s literature for additional information.
When the propulsion engine(s) or generator is
running, CO is produced and may remain in the
vicinity of the exhaust outlet (including underwater
exhaust outlets such as sterndrives and outboards).
Refer to Figure B14.
P. Ventilation of Accommodation
Accommodation spaces need to be ventilated to
introduce fresh air into the spaces. Ventilation meth-
ods (e.g. windows, hatches, doors, and blowers)
used to accomplish this may, under certain conditions,
bring hazardous levels of CO into the occupied
spaces. Care should be taken to be aware of all
prevailing conditions when using these ventilating
. Do not occupy aft lounging area(s)
or swim platform.
. Do not swim under or around swim platform.
. Do not swim in the vicinity of the exhaust outlet.
Q. Running of Engines in Idle
Engines running in idle exhaust carbon monoxide
that can accumulate near the hull of the boat. Do not
stand or swim near the engine exhaust or outdrive
when engines are idling or generator is running.

R. Altitude and Sea Conditions
M. Dangerous Activity -
Operation at altitudes greater than 5,000 feet con-
tributes to inefﬁcient engine performance and may
require adjustments to the ignition systems, fuel
systems, or changing the propeller’s size or gear ratio.
Do not sit on, occupy or hang on any stern append-
ages (e.g., swim platforms, boarding ladders, etc.)
while underway. Do not body surf, commonly known
as “teak surﬁng” or “dragging”, etc. in the wake of the
boat. Do not tow persons in close proximity to the
stern of the boat. See Figure B15.
Failure to make adjustments to ignition systems
and/or fuel systems for altitude conditions may
cause an increase in CO production.
Reduced power resulting from increased altitude
may require adjustments to propeller size.
