    The calculated course would be difficult to steer because the required
    heading changes continuously throughout the voyage. Mercator methods
    give a rhumb line, much easier for a sailor to follow. Besides, they
    are practical without electronics, so are closer to the spirit of this
    list. I suspect your suggestion would be too much for a navigator to
    handle without electronic help.
