Contact the detector manufacturer, the Pur-
suit Customer Relations Department or your
local fire department for assistance in finding
and correcting the situation.
In certain situations, boats can have a prob-
lem due to the “station wagon effect” where
engine exhaust fumes are captured in the
vessel by the vacuum or low pressure area,
usually the cockpit, bridge deck and cabin,
that can be created by the forward speed of
the boat. Boats that are underway should
close all aft facing portholes, hatches and
doors. The forward facing deck hatches
should be open whenever possible to help
pressurize living spaces of the boat. Sleep-
ing, particularly in aft cabins, should not be
permitted while underway. Proper ventilation
must be maintained on the bridge deck by
opening a forward window or windshield to
drive fumes away from the occupants. The
canvas drop or aft curtain must be removed
and side curtains should be opened or
removed to increase airflow and maintain
proper ventilation whenever the engines are
running.
DO NOT operate the engines with side cur-
tains closed and the aft or drop curtain
installed.
Use extreme caution while anchored or in a
slip and an auxiliary power generator is
operating. Calm wind nights can easily allow
fumes to enter the boat. Inspect the exhaust
systems of propulsion and the auxiliary gen-
erators, if equipped, frequently for possible
leaks. High concentrations of CO in your
boat can originate from an adjacent boat
through open hatches or windows.
Failure to properly ventilate the boat while
the engines are running can cause CO to
accumulate within the cabin. Make sure to
ventilate the boat and to avoid CO from
accumulating in the boat whenever an
engine is running.
