14.1.1 Subject to 14.1.3, the master of a ship must take all reasonable steps to have navigational equipment maintained in efficient working order.
14.1.2 The owner of a ship must ensure that appropriate spare parts and suitable tools for repairs to navigational equipment fitted on the ship are provided on the ship.
14.1.3 Except as provided in SOLAS regulations 7(b)(ii), 8 and 9 of Chapter I of SOLAS, if a defect is discovered at a place where repair facilities are not available, the ship may proceed to a port where repairs can take place, provided that suitable arrangements are made by the master to take the inoperative equipment or unavailable information into account in planning and executing a safe voyage to that port.
Note: It may not be necessary for permanent repair facilities to be available at the port. It may be practical, for example,for appropriate expertise and/or equipment to be brought to the port for the purpose.
14.2 Instructions
The owner of a ship must ensure that adequate information and instructions written in English (or in the case of a foreign ship, a language acceptable to the flag State of the ship) about the use and maintenance of all navigational equipment installations on the ship are provided on the ship.
14.3 Magnetic compass
14.3.1 The master of a ship over 100 gross tonnage must keep a compass deviation book in which is to be recorded the information specified in Appendix 1.
14.3.2 The master of a ship must ensure that observations for the purpose of ascertaining compass errors are made at appropriate intervals and recorded in the compass deviation book.
14.3.3 The master of a ship must ensure that, if the observations for a standard magnetic compass on the ship show an excessive deviation, the compass is adjusted by a licensed compass adjuster at the next port where an adjuster is available, to correct the deviation.
14.3.4 The master of a ship must ensure that for each magnetic compass, the tables or curve of residual deviations from the last adjustment, and details of subsequent changes in deviations, are available for use at all times.
14.3.5 The master of a ship must ensure that the size and position of magnets and soft iron correctors in a compass and the date and nature of any changes made to those items or to their position at any time are recorded in the compass deviation book.
Note: In particular, it may be desirable to alter the height of the vertical magnets in order to reduce oscillations of the compass due to rolling (heeling error) when on northerly or southerly courses. Such alteration of the heeling error corrector may affect the compass deviation on various headings and appropriate precautions should be taken.
14.3.6 On completion of an examination and adjustment of a ship's compasses under 14.3.3, the adjuster must provide the master with a table of deviations in accordance with Form MO—21/1 in Appendix 2.
14.3.7 If, in relation to a ship:
(a) one or more of the requirements of 14.3.2, 14.3.3, 14.3.4 and 14.3.5 has not been complied with; and
(b) a surveyor has reason to believe that the compasses of the ship are, or may be, unreliable,
the surveyor may direct the master of a ship to have the ship's compasses adjusted in accordance with 14.3.3.
14.3.8 The master of a ship must comply with a direction under 14.3.7 as soon as practicable.
14.3.9 For this provision:
appropriate intervals means at least once on each watch.
excessive deviation means for a standard magnetic compass, the deviation of the compass on a heading is more than 5°.
Note A deviation may be permanently or temporarily excessive after an event, eg if a ship has been laid up for a long period, structural alterations, grounding, structural damage caused by fire, being hit by lightning, passing an area of magnetic anomaly or carrying a cargo of ferromagnetic materials that are magnetised or may become magnetically induced.
14.4 Licence as Compass Adjuster
14.4.1 A person may apply to the Manager, Ship Operations and Qualifications, for the issue of a Licence as Compass Adjuster.

(a) has successfully completed a course, approved by the Manager, Ship Operations and Qualifications, on adjustment of compasses; and
(b) has assisted in adjusting the compasses of at least 12 ships during the previous three years,
the Manager, Ship Operations and Qualifications, is to issue that person with a Licence as Compass Adjuster.

14.4.6 The General Manager, or a person authorised by the General Manager for the purpose, may cancel at any time a Licence as Compass Adjuster that has been obtained by reason of a false representation.
