7.2.11 Ventilation
V
entilation is a ver
y
important issue with
y
our boat, with
the potential for Carbon Monoxide buildup
(

f
et

S
ection
)
, alon
g
with the simple com
f
ort o
f
f
resh
air or air conditionin
g
, ventilation is a standard that is a
necess
i
t
y.
O
n
y
our boat, there are essentiall
y
three t
y
pes of ventila-
tion, the air conditionin
g
s
y
stem
(
AC s
y
stem
)
, the blower,
and the Bomar hatches, which suppl
y
y
ou with
f
resh
air when opened. Since the air conditionin
g
s
y
stem is
AC powered
(
see AC Electric Section
)
and the hatches
require no power, we will detail the blower
(
or
f
ans
)
, and
their function, here.

7.2.12 Fire Extin
g
uishin
g
S
y
stems
In the en
g
ine room, there is a
f
ire extin
g
uishin
g
bottle
installed. This s
y
stem is D
C
powered with the rela
y
, or
“
module”, and the alarm at the helm station.
When a
f
ire is detected on
y
our boat, the alarm will sound
and set off the Halon bottle. This rela
y
will shut down the
e
n
g
ines, the blowers, and the
g
enerator. To reset the
s
y
stem, activate the reset switch on the monitor at the
helm. See Fi
g

7.2.13 Shower Sump
The shower sump is part of the Sanitar
y
S
y
stem and

ormation about the
S
hower
S
ump can be
f
ound
in that section. However, the breaker control for the
S
hower Sum
p
can be found on the MDP
.
7.2.14 Windlas
s
Your boat ma
y
be equipped with an optional windlass. It
receives its power from the DC electrical s
y
stem. The
windlass offers
y
ou the abilit
y
to raise and lower
y
our
anchor. There is also a circuit breaker at the batter
y
switch. The windlass can be operated from the bow. See
manufacturer’s owner’s manual about the
p
ro
p
er and
sa
f
e operatin
g
procedures.
