how to calculate reciprocal course

by Melany Treutel 5 min read

Reciprocal course can be obtained by simply adding 180 degrees to the original course if original course is less than 180. When the heading shows 310 degrees (i.e. 20 degrees short of 290 degrees) rudder is put to midship. Williamson turn is ideal method in reduced visibility.

Take away a two from one place, and add it to the other. For example, with 120 degrees, move the two from right to left-subtract it from the 2 and add it to the 1-to get the reciprocal of 300 degrees.Apr 5, 2004
