Compass
A compass is installed on each boat to aid in navigation. A magnetic compass is often deflected by iron,
magnets, or electrical current from nearby wiring and must be adjusted to compensate for these
influences. Only a qualified technician should perform compass adjusting/compensation. Since it is
seldom possible to correct compass deviation to zero, a deviation card is created to indicate the correct
heading that must be utilized when navigating by compass. Keep this card near the helm and refer to it
as necessary.
