    There is something wrong somewhere, my computation gives 129° TRUE and H.O. 214 comes up with about 128°. Are you using MAGNETIC directions? Variation is 12° west making the magnetic course 141° .

    I'm in Phila. PA and when I enter the Lat/Lon of Bermuda into my GPS and request a course I get 142 degrees. When I enter the same figures in the online program called Great Circle Sailing I get 101 degrees.
    Anyone know why this happens?
