Figure B14: Exhaust Gas Accumulation-Dangerous Activity
Boats having fuel burning appliances in accommodation
areas should be provided with adequate ventilation and
the appliance should be maintained to function properly.
Figure B12: Operating at Slow Speed with Following Wind
Be aware that cockpit and deck drains can be a
source of CO ingress into boats, especially boats O. Air Conditioning
with cockpit or decks enclosed with canvas or per-
manent boat structures.
Lack of system maintenance may cause CO to be brought
into the air-conditioned spaces by the air conditioner (if
Please refer to the air conditioner
manufacturer’s literature for additional information.
L. Accumulation of Exhaust Gases-Swim Platform
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):
VentilationofAccommodation (Occupied) Spaces
Accommodation spaces need to be ventilated to introduce
fresh air into the spaces. Ventilation methods (e.g. win-
dows, 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
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
Refer to Figure B13.
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 en-
gines are idling or generator is running.
R. Altitude and Sea Conditions
Operation at altitudes greater than 5,000 feet contributes
to inefficient engine performance and may require adjust-
ments to the ignition systems, fuel systems, or changing
the propeller’s size or gear ratio.

M. Dangerous Activity - “Teak Surfing”/“Dragging”
Failure to make adjustments to ignition systems and/
or fuel systems for altitude conditions may cause an
increase in CO production.
Do not sit on, occupy or hang on any stern appendages
(e.g., swim platforms, boarding ladders, etc.) while un-
derway. 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 B14. This activity can also increase
the possibility of injury due to contact with a rotating pro-
Reduced power resulting from increased altitude may
require adjustments to propeller size.
