Location of ventilators
and air intakes
NOTE! Air intakes or outlet holes must never be in-
stalled in the transom. The air in this area is mixed
with water and exhausts and must therefore never be
allowed to enter the boat.
Function of air intakes
Air intakes and outlets must function well, even in
bad weather, and must therefore have efficient water
traps. Soundproofing must usually be built in.
The air intake and outlet should be placed as far
away from each other as possible so that a good
through-flow is obtained.
If the intake and outlet are too close, the air can recir-
culate resulting in poor ventilation.
