7.2.4 Lighting Systems
There are basically four different lighting systems aboard
your boat. These are the interior and exterior lighting,
the safety and navigational lighting, and, if supplied, the
courtesy lighting.
The interior and exterior lighting systems are separated
because of the method in which power is supplied to the
two systems. The interior lights are powered from the
MDP and marked Cabin Lights. The exterior lighting is
powered from the MDP and have switches on the main
control panel for their operation.
The next area, safety and navigational lighting, closely
follows Coast Guard regulations regarding safety and
navigational lights. They are as follows:
Nav Lights
Steaming Light
Mast Light
Deck Light
The red and green lights on the bow rail and the white
facing light on the transom are known as “Nav Lights”.
These lights should always be on when motoring.
The “steaming” light is the forward facing light mounted
halfway up the mast. This should be on when underway
with sail power only.
The anchor light is a 360° light mounted at the top
of the mast and should only be on when anchored.
The engine area lighting is controlled by the courtesy light
breaker, and the Deck light gives lighting to the foredeck
area.
Lighting circuits and locations are outlined in the end of
this chapter.
7.2.5 CO Monitors
In each area aboard your boat, you will find a CO Monitor
(Carbon Monoxide Monitor). We care about your safety
and have installed these CO Monitors to show our con-
cern. For more information about the CO Monitors
mounted on your boat, consult your owner’s packet and
find the documentation for the CO Monitors.
7.2.6 Entertainment Centers
The entertainment centers in the berthing areas of your

boat are 12 volt DC powered. The power is supplied
through the distribution panel. The television is AC pow-
ered from a DC to AC inverter, and the stereo is DC
powered. More information about the controls of your
entertainment centers and equipment can be found in
your owner’s packet.
7.2.7 Oil Changer (Option)
Your boat may be equipped with the optional oil changer.
The oil changer receives its power from the DC Electrical
System. The breaker is located on the Battery Switch
Panel. The breaker is marked “OIL CHANGER.”
Consult your mechanical arrangement for the location of
the oil changer.
Note: Discharge of oil is prohibited. The Federal Water
Pollution Control Act prohibits the discharge of oil or oily waste
into or upon navigable waters and contiguous zone of the
United States. If such discharge causes a film or sheen upon,
or discoloration of the surface of the water, or causes a sludge
or emulsion beneath the surface of the water, violators are sub-
ject to a penalty of $5,000.
7.2.10 Bilge Pump Systems
Your boat is equipped with one main bilge pump and
one (optional) emergency bilge pump. For locations
of the bilge pump systems, consult your Mechanical
Arrangement Drawing or the Sanitary Systems Drawing.
The Bilge Pump System consists of a pump and a float
switch. When the water level rises far enough to activate
the float switch, this activates the pump which lowers the
water level down to a point that the float switch stops the
power. Fig. 7.10 shows you the typical wiring.
For more information about your bilge pump system, see
Sanitary Systems.
