+## rhumbBearing
+
+Takes two [points][1] and finds the bearing angle between them along a Rhumb line
+i.e. the angle measured in degrees start the north line (0 degrees)
+
+**Parameters**
+
+-   `start` **[Coord][2]** starting Point
+-   `end` **[Coord][2]** ending Point
+-   `options` **[Object][3]?** Optional parameters
+    -   `options.final` **[boolean][4]** calculates the final bearing if true (optional, default `false`)
+
+**Examples**
+
+```javascript
+var point1 = turf.point([-75.343, 39.984], {"marker-color": "#F00"});
+var point2 = turf.point([-75.534, 39.123], {"marker-color": "#00F"});
+
+var bearing = turf.rhumbBearing(point1, point2);
+
+//addToMap
+var addToMap = [point1, point2];
+point1.properties.bearing = bearing;
+point2.properties.bearing = bearing;
+```
+
+Returns **[number][5]** bearing from north in decimal degrees, between -180 and 180 degrees (positive clockwise)
