The Significance Of Correcting The Yacht Magnetic Compass.

The yacht magnetic compass is a navigational pointing instrument that makes use of the interaction principle of magnetic needle and other magnetic sensitive elements in the geomagnetic field to make the compass indicate magnetic north. Because of the simple structure of the magnetic compass, reliable performance, do not need to rely on other external conditions, known as one of the necessary instruments of the ship.

Yacht magnetic compass is a pointing instrument that relies on the earth's magnetic field to attract magnetic needles. It is characterized by simple structure, reliable performance, durable, easy maintenance and so on, so it has become one of the necessary navigation instruments for modern ships. However, due to the influence of ship magnetism, the pointing of magnetic needle cannot completely point to magnetic north, but to the combined direction of Earth magnetic field and ship magnetic field. This deviation is called the magnetic compass deviation. Therefore, the ship pilot must understand the reason of magnetic compass deviation, correction method and residual deviation measurement, so as to ensure the safety of navigation.
