    Sean,

    Thank you for the effort which looks considerable.  I noticed in Bowditch Chapter 24, "The Sailings" mention of the Traverse tables.

    Also, I gave these a try and they work-

    DR Longitude = Lf+t(V/60)sinT/cosBf

    DR Latitude = Bf+t(V/60)cosT

    ...where

    • Lf = Longitude of the last fix
    • Bf = Latitude of the last fix
    • t = Time elapsed
    • V = Speed
    • T = Course

    Very nice.

    Thanks,

    Sam L.
