Magnetic Compass Adjustments and Deviation Curve

This involves an examination of the compass position for deviating objects. The vessel is then swung to obtain a deviation curve. If deviations are excessive and correctors are fitted to compass position then corrections can be made to reduce deviations.



Initial consultations are always free of charge or obligation.
