Members and clients are therefore advised to take note of the warning published by AMSA and ensure that Masters and crew are aware of their responsibility under international regulations to monitor the performance of magnetic compasses at regular intervals, adjust as necessary and record deviations in a compass deviation book.

All Magnetic Compasses are vulnerable to magnetic interference, which will produce errors, called deviation. It is the Owner/Operator and/or Helmsman’s responsibility to make sure the compass is properly installed and compensated.

Compensation is the act of correcting for MAGNETIC deviation aboard your boat.

A graduated scale, called a card, is wrapped around the float and viewed through a glass window with a lubber line across it. The effects of these onboard magnetic fields on the compass change with the vessel’s heading.

The difference of the compass’s north from the magnetic north on the different headings is called deviation. Compass adjustment is the compensation of these deviating forces with correctors. Handbook of Magnetic Compass Adjustment, 1st Edition, US Government.

Vessel owners and masters each have responsibilities for ensuring that magnetic compasses are maintained in good working order, adjusted and a table or curve of residual deviations is performance of the compass should be monitored and, for a vessel more than GT, deviations recorded in a compass deviation book at regular intervals, ideally at least once every watch and also.

Compass adjusting sea-going vessel. Magnetic compasses should be adjusted when: they are installed for the first time; they have become unreliable; repairs or structural alterations have been made to the ship that could affect its permanent and/or induces magnetism; electrical or magnetic equipment close to the compass is added, removed or altered.

Vessel owners and masters must ensure that magnetic compasses are maintained in good working order, adjusted and a table or curve of residual deviation is available. The Australian Maritime Safety Authority has issued Marine Notice No of (copy attached) highlighting the importance of maintenance and adjustment of magnetic compasses.

Magnetic North to be so many degrees East or West. Example: Magnetic declination 11 degrees West means The North arrow of the lensatic compass will point 11 degrees West of True North. Place the fully opened compass on the map with the scale edge alongside a.

Magnetic Compass Adjuster course enables ship’s officer to carry out the adjustment themselves and keep compass calibrated to avoid SIRE findings. According to AMSA, failure to maintain a magnetic compass in a good working order or to monitor deviations may result in a vessel being delayed or detained, and the vessel owner and/or Master can.

Compass Adjusting Services offers an ongoing training / certification program. The objective of this training / certification is to highlight some important adjuster skills, traits, abilities, and increase the opportunity for deployment.

The goal is now to adjust out the local magnetic field that has just messed us up by 10 degrees by using the N-S adjustment in the compass. This is done by turning the boat degrees and adjusting out 1/2 the difference from magnetic south that you observe.

Compass Adjustment is the method of analyzing and compensating for deviating forces of a vessel’s magnetic compass. A magnetic compass should always align steadily to the earth’s magnetic field, pointing to magnetic north. However, steel, electronic instruments or equipment, and even the type of cargo carried, can cause the compass needle.

Principal Surveyor John Hall holds an unlimited marine compass adjuster's licence and has adjusted compasses on many hundreds of seagoing ships and boats of all types and sizes.

He has installed new compasses on offshore & cargo vessels, fishing. The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earth's North magnetic pole.

GILLIE'S book contains within its small compass all the information necessary for those who wish to understand the factors on which the efficiency of the magnetic compass depends.

Among its. The oldest and most familiar type of compass is the magnetic compass, which is used in different forms in aircraft, ships, and land vehicles and by me in the 12th century, mariners in China and Europe made the discovery, apparently independently, that a piece of lodestone, a naturally occurring magnetic ore, when floated on a stick in water, tends to align itself so as to point.

The sources of magnetic deviation vary from compass to compass or vehicle to vehicle.
