    The attached  image is a sanity check. Beacause of the way the map is drawn I have had to measure the long way  bearing which  is 90° + 26° - 116°. The  short way  bearing is 180° - 116° = 64° which is acceptably (to me) close the the figure of 65° which I previously quoted.

    Who needs spherical trgionometry?
