The Significance Of Correcting Yacht Magnetic Compass.

The yacht magnetic compass is a navigational pointing instrument that uses the interaction principle of magnetic sensitive elements such as magnetic needles in the geomagnetic field to make the compass indicate magnetic north. Because the magnetic compass is simple in structure and reliable in performance, it does not need to rely on other external conditions and is called one of the necessary instruments for ships.

     The yacht magnetic compass is a pointing instrument manufactured by relying on the ability of the earth's magnetic field to attract a magnetic needle. It is characterized by simple structure, reliable performance, sturdiness and durability, and easy maintenance, so it has become one of the necessary navigation instruments for modern ships. However, due to the influence of the ship's magnetism, the direction of the magnetic needle cannot completely point to the magnetic north, but to the direction of the resultant force of the earth's magnetic field and the ship's magnetism. This deviation is called the magnetic compass self-difference. Therefore, ship pilots must understand the causes of magnetic compass self-difference, the correction method and the determination of residual self-difference, etc., to ensure the safety of navigation.
