What is bearing in direction?
A bearing provides a direction given as the primary compass direction (north or south), degree of angle, and an east or west designation. A bearing describes a line as heading north or south, and deflected some number of degrees toward the east or west. A bearing, therefore, will always have an angle less than 90°.

What is a heading in nautical terms?
In the nautical sense, a “heading” is the direction your vessel is pointing, and the direction you would travel if you were making way would be the resultant vector of this orientation, taking into account the simultaneous effects of winds, currents and tides. A bearing on the other hand is an expression of your position relative to some other (either fixed or moving) reference point, which then establishes your your line of position. Multiple bearings can be taken to determine converging lines of position . . . thereby determining your actual position - as one might pinpoint on a nautical cha
