GENERAL INFORMATION
12
The primary concern is the boat changing direction while in the midst of the jump. In such case the landing may
cause the boat to veer violently in a new direction. Such a sharp change in direction can cause occupants to be
thrown out of their seats, or out of the boat.
WARNING
Avoid serious injury or death from being thrown within or out of a boat when it lands after jumping a wave or
wake. Avoid wave or wake jumping whenever possible. Instruct all occupants that if a wake or wave jump occurs,
get low and hang on to a boat hand hold.
There is another less common hazardous result from allowing your boat to launch off a wave or wake. If the bow
of your boat pitches down far enough while airborne, upon water contact it may penetrate under the water surface
and submarine for an instant. This will bring the boat to a nearly instantaneous stop and can send the occupants
flying forward. The boat may also steer sharply to one side.
Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal combustion engines. This includes the outboards,
sterndrives and inboard engines that propel boats, as well as the generators that power various boat accessories.
Carbon monoxide is a deadly gas that is odorless, colorless and tasteless.
Early symptoms of carbon monoxide poisoning which should not be confused with seasickness or intoxication,
include headache, dizziness, drowsiness, and nausea.
WARNING
Avoid the combination of a running engine and poor ventilation. Prolonged exposure to carbon monoxide in
sufficient concentration can lead to unconsciousness, brain damage, or death.
GOOD VENTILATION
Ventilate passenger area, open side curtains, or forward hatches to remove fumes.
Example of desired air flow through the boat.
POOR VENTILATION
Under certain running and/or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits with
insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.
