5. Operating a boat at slow speeds with a following
wind should be avoided. Consider changing direc-
tion, adjusting speed, or both. See Figures B13.

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 plat-
form.
2. Do not swim under or around swim platform.

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

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 prop-
erly.
O. Air Conditioning
Lack of system maintenance may cause CO to be
brought into the air-conditioned spaces by the air con-
ditioner. Please refer to the air conditioner
manufacturer's literature for additional information.
P. Ventilation of Accommodation (Occupied)
Spaces
Accommodation spaces need to be ventilated to intro-
duce fresh air into the spaces. Ventilation methods (e.g.
windows, hatches, doors, and blowers) used to accom-
plish this may, under certain conditions, bring hazard-
ous levels of CO into the occupied spaces. Care should
be taken to be aware of all prevailing conditions when
using these ventilating methods.
