The deviation of the standard compass must not exceed 5° on any given compass point after adjustment by an adjuster of compasses under these Regulations.\n\n(2) Where the Deputy-Director is satisfied that the deviations of a ship’s compasses have been satisfactorily ascertained and adjusted he shall issue a Compass Certificate for the ship in Form C 4.\n\nCompass-error register book.\n\n10.—(1) The master of every ship over 100 tons gross register registered in Australia or licensed to engage in the coasting trade, or regularly trading from a port in the Commonwealth as head-quarters, and to which these Regulations apply, shall keep a compass-error book, substantially in accordance with Form C 5, in which shall be accurately recorded particulars of observations taken, the approximate position of the ship at the time, the different points of the vessel’s head and the deviations and errors of the standard compass on those points; also the size and position of the magnets and soft-iron correctors for the standard compass, and the date and nature of any changes at any time made in them or their positions.\n\n(2) Observations for the purpose of ascertaining compass-errors shall be made and recorded as frequently as practicable.\n\n(3) The compass-error register book shall be produced to a surveyor or inspector, on demand, and when so produced shall be signed and dated by that official, provided he is satisfied that the register book has been kept in accordance with these regulations.\n\nIssue of licences to compass adjusters.\n\n11.—(1) Subject to compliance by applicants with the requirements of regulations 13 and 14, the Deputy-Director may issue licences, in accordance with Form C 6, to the following persons, authorizing them to examine and adjust compasses and to compute their deviations, that is to say, to—\n\n(a) adjusters of compasses holding valid licences issued by the Government of any State, or any Marine Board or other authority approved by the Minister;\n\n(b) persons holding a certificate of competency as Extra Master recognised by the Board of Trade of the United Kingdom;\n\n(c) persons holding a certificate of competency as Master (other than Extra Master) recognised by the Board of Trade of the United Kingdom, and who have been at least one year in command of a foreign-going vessel, and who produce satisfactory evidence that they have passed the examination prescribed under the Act, or by the Board of Trade of the\n\n \n\nUnited Kingdom, or by any Marine Board or authority approved by the Minister, in the syllabus of the laws of the deviation of the compass in iron ships, and in the means of compensating or correcting such deviation.\n\n(2) No person shall act as an adjuster of compasses unless licensed in accordance with this regulation.\n\nCancellation of licences\n\n12.—(1) The Deputy-Director may at any time, by order under his hand, cancel any licence issued to an adjuster of compasses.\n\n(2) A copy of the order, stating the cause of cancellation, shall be delivered to the adjuster of compasses or transmitted by registered post to his last-known address in the Commonwealth.\n\n(3) The adjuster of compasses may appeal to the Director of Navigation against the order.\n\n(4) If no appeal is made to the Director of Navigation within fourteen days after the delivery or posting of a copy of the order, or if on appeal the order is confirmed by the Director of Navigation, the licence shall be void, and shall forthwith be delivered up to the Deputy-Director.\n\nApplication for licence\n\n13. The application for a licence shall be in accordance with Form C 7, and shall be accompanied by the applicant’s certificate of competency or commission, and with satisfactory evidence of good conduct and character during the twelve months immediately preceding the date of his application.\n\nLicence fee.\n\n14.—(1) An annual fee of One pound shall be payable, in advance, to the Deputy Director, on the 1st July in each year in respect of each licence issued; provided that in respect of a licence issued after 1st January in any year, the fee for the unexpired portion of the year shall be Ten shillings.\n\n(2) If the licence-fee be not paid on or before the due date, the Deputy Director may, by order under his hand, cancel any licence.\n\nApplication for services of adjuster of compasses.\n\n15.

\n```\n\nNotice to Masters and Navigating Officers.\n\n(To be printed inside front cover of Compass-error Register Book.)\n\nOfficers should understand that the object of tentative adjustment is to bring the deviations within management limits, and also to equalize the directive force of the needle so far as is practicable on all courses; but no system of adjustment whatever is sufficiently reliable in character to absolve the navigator from the necessity of using every precaution, and especially of ascertaining the deviation on every available opportunity by observations of the sun by day and the other heavenly bodies by night.—(Extract from Board of Trade Instructions on Compass Adjustment.)\n\nForm C 6.\n\nCommonwealth of Australia.\n\n\\_\\_\\_\\_\\_\\_\\_\\_\\_\\_\\_\\_\n\nNavigation Act 1912–1920.\n\n(seal).\n\nNav.
