    Yes, this?s true, but I think that Rhumb Line is only the line on the surface 
    of the earth, ( spherical or oblate), of a Mercator Sailing, also called 
    loxodrome
    >Mercator Sailing:
    >        Provides a solution to the plot as made on a mercator chart. Uses
    >meridonial differences and difference of longitude in place of
    >difference of latitude and departure, respectively.
    >
    >Rhumb Lines:
    >        Maintains a true direction. Makes the same angle with all meridians
    >it crosses. Maintains a straight line on a mercator chart. The
    >difference between the Rhumb line and the Great Circle connecting two
    >points increases as (1) as the latitude increases, as the difference in
    >latitude between two places decreases, and (3) as the difference of
    >longitude increases.
