    Re: Ocean swells for direction

    Dr David Lewis gave details of traditional navigation
    in the Pacific in several books   - "We, the
    Navigators" being the most focussed on this. There are
    also several books on "emergency navigation" which are
    interesting (the stand-out being the one by David
    Burch). From memory, there was a pull-out appendix to
    one edition of "Survive the Savage Sea" which had quite
    of lot of info, too.
    As to practical sailing experience, once into ocean
    swells you can steer minute-by-minute by swell, but
    over a day you need sun or stars as well. Lewis says
    that the Pacific navigators found that the best way to
    sense swells is to stand up and let the swing of your
    testes tell you...though that could just be a
    cock-and-bull story.
