Yacht Council.
Periodic inspection and cleaning of the ventilation ducts
isnecessarytoensureadequateaircirculation. Abuildup
of leaves, twigs, or other debris can severely reduce ven-
tilation. Be sure bilge water does not accumulate to a
level that would obstruct the ventilation ducts.
Blower operation can be tested by placing a hand over
the vents. DO NOT rely on the sound of the blower. Be
sure a substantial amount of air is being exhausted by
the bilge blower. Check the bilge blower system often,
preferably before each cruise.
