                    TC 106.0 deg  Estimated time  24 hours and 13 minutes
            #2  Adding current vector, speed goes from 9.5 to 9.85 kts and
                    direction goes from TC of 106 to direction with added vector
    is                 107.1 deg
                Correcting for the current vector, the needed TC is 104.8 which is
