Know the Dangers!
Swimming near or under the back deck or swim platform. Carbon monoxide from exhaust pipes
of inboard engines, outboard engines and generators build up inside and outside the boat in
areas near exhaust vents. STAY A A AWA W W Y A A from these exhaust vent areas and DO NOT swim in
these areas when the motor or generator is operating. On calm days, wait at least 15 minutes
after ff the motor or generator has been shut off ff before entering these areas. NEVER enter an
enclosed area under a swim platform where exhaust is vented, not even for a second.
It only t y akes one or two breaths of the air in this “death chamber” for it to be fatal.
Blockage of exhaust outlets can cause carbon monoxide to accumulate in the cabin and cockpit
area - even when hatches, windows, portholes, and doors are closed.
Exhaust from another vessel that is docked, beached, or anchored alongside your boat can emit
poisonous carbon monoxide gas into the cabin and cockpit of your boat. Even with properly vent-
ed exhaust, your boat should be a minimum of 20 feet from the nearest boat that is running a
generator or engine.
Slow speeds or idling in the water can cause carbon monoxide gas to accumulate in the cabin,
cockpit, bridge, and aft ff deck, even in an open area. A tailwind (force of wind entering from aft ff
section of the motorboat) can also increase accumulation.
The “station wagon effect,” ff or backdrafting ff can cause carbon monoxide to accumulate inside the
cabin, cockpit, and bridge when operating the boat at a high bow angle, with improper or heavy
loading or if there is an opening which draws in exhaust.
This effect ff can also cause carbon monoxide to accumulate inside the cabin, cockpit, aft ff deck,
and bridge when protective coverings are used and the boat is underway.
Teak T T surfing, dragging and water-skiing within 20 feet of a moving watercraft ff can be fatal.
