    Ocean swells for direction
    From: Frank Swift
    Date: 2004 Feb 14, 12:31 -0800

    I remember back in the '50s that the Bahamians sailed from Andros to
    Nassau without using a compass.
    They knew the direction from Andros Island and would set sail in that
    direction.
    When the wind direction changed,they would alter their course noting at
    the time the direction of the swell so they knew what direction they
    would have to make good after changing their course.
    The reason this worked was that the direction of the swell would change
    some time after the wind direction changed.
    That, plus looking for the reflection of the land (dark) under the
    clouds enabled them to reach Nassau while transiting the area known as
    the Tongue of the Ocean.
