6. 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 per-
manent boat structures.
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):
1. Do not occupy aft lounging area(s) or swim platform.
2. Do not swim under or around swim platform.
3. Do not swim in the vicinity of the exhaust outlet.
Refer to Figure B13.

M. Dangerous Activity - "Teak Surfing"/"Dragging"
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-
peller.

N. Cabin Appliances
Boats having fuel burning appliances in accommodation
areas should be provided with adequate ventilation and the
appliance should be maintained to function properly.
O. Ventilation of Accommodation (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
be aware of all prevailing conditions when using these ven-
tilating methods.
P. 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.
Q. 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.
1. Failure to make adjustments to ignition systems and/
or fuel systems for altitude conditions may cause an
increase in CO production.
2. Reduced power resulting from increased altitude may
require adjustments to propeller size.
3. Heavy sea or out of trim conditions tend to load en-
gines resulting in reduced performance and thereby
increasing their CO production.
