Compass bearings<\/h4>\n

The angle between the direction of a place or object and compass north is called the compass bearing.\u00a0 As previously stated it is distinguished by the suffix (C) after the bearing.\u00a0 Like true and magnetic bearings it is written in three figure notation.\u00a0 In order to change a compass bearing to a true bearing, the navigator must correct it for deviation and variation.\u00a0 It is important to remember that the heading of a vessel determines the amount of deviation.\u00a0 All bearings taken whilst on a particular course must be corrected according to the amount of deviation determined by the ship\u2019s heading.\u00a0 Only when the ship alters course will the amount of deviation change.<\/p>\n

Procedure for converting compass bearings<\/h4>\n

When converting a compass bearing to a true bearing one must first remove the deviation.\u00a0 This will provide one with a magnetic bearing.\u00a0 By next applying the variation correction one will finally arrive at the true bearing.\u00a0 If the deviation is easterly, it must be added to the compass bearing.\u00a0 If the variation is also easterly it must be added to the magnetic bearing.\u00a0 In both cases, if the deviation and variation is westerly, they will be subtracted from the compass and magnetic bearings respectively.\u00a0 If one needs to convert a true bearing to a magnetic and compass bearing, the reverse of the above is applicable, ie you subtract the easterly deviation and variation and add westerly deviation\/variation.\u00a0 The following is a good aide memoir.<\/em>
