WebA marine compass is oriented so the N-S line of the compass runs through the pivot point on the compass dial and an index mark on the compass’s base. This is called a "lubber’s line." This line needs to be aligned along the centerline of the craft: bow/north; stern/south. Take the time to orient the N-S line because a slight offset of only ... WebHow do I correct my compass to the true bearing? You can compute the true bearing from a magnetic bearing by adding the magnetic declination to the magnetic bearing. This works as long as you follow the convention that degrees west are negative (i.e. a magnetic declination of 10-degrees west is -10 and bearing of 45-degrees west is -45).

WebThe clockwise angle on the other side is needed. Use the angle fact that angles in a full turn add to 360°. To work the bearing, subtract 130° from 360°. 360° – 130° = 230° and so, the bearing of A from B is 230°. Here is another example of bearings using interior angles. For example, find the bearing of B from A. WebThe bearing to the object is determined by calculating the number of degrees clockwise from 000° to the object.

WebThe compass can be dragged and positioned to point in any direction and routes can then be plotted. The compass will automatically adjust for differences between magnetic and true north for any location and also provide the latitude and longitude coordinates of your routes.
