Compass
A Ritchie magnetic compass (Figure 3-48) is mounted on the starboard dash
panel, centered over the coxswain console. It is the standby or backup
compass used for navigation. The compass contains an internal gimbal
system for maximum stability during adverse weather conditions. Built-in
compensators provide for easy compass deviation adjustments. The blue dial
is calibrated in white 5-degree increment markings. Lubber lines are
provided at 45 degrees.

Magnetic compass deviation may occur when cabin electrical equipment (windshield wiper
motors, cabin fan motors, or heater) is energized creating EMI.
