BOMBARDIER SeaDoo Speedster 200 Operator's Manual page 20

While underway, CO concentrations can increase by backdrafting or "the station
wagon effect". Backdrafting is caused by factors such as relative wind direction,
speed, or the bow being too high. To prevent this, open canvas whenever possible
to provide positive airflow through the hull.
Boat houses, seawalls, and other boats in close proximity or confined areas can
contribute to increased CO levels. Operators must be aware that operation, moor-
ing, and anchoring in an area with other boats puts them in jeopardy of CO accu-
mulation from other sources. Likewise, a boat operator must be aware of how
exhaust from his boat will affect others. Operation of the engines while moored
may cause CO accumulation in your boat and those around you.

CONFINED AREAS
Be sure to provide adequate ventilation. If the windshield has vents, open them
before getting underway to increase positive air flow and decrease the chances
of CO accumulation.
Backdrafting! Under certain conditions, moving air currents can direct poi-
sonous CO fumes into boat. These fumes can accumulate to dangerous
levels without proper airflow. Provide adequate ventilation, redistribute
the load or bring boat out of high bow angle.
Exhaust Fumes! Hull exhaust from your boat can cause excessive accumu-
lation of poisonous CO gas within cockpit area when using protective
weather coverings while underway or while stationary. Provide adequate
ventilation when the canvas top, side curtains, and/or back curtains are in
their closed protective positions.
