    The navigationally interesting aspect of voyaging to the east from
    established areas of Polynesia to South America is that it is uphill
    all the way! Meaning that travelling due east from these tropical and
    semi-tropical zones would involve sailing against the prevailing
    south-east trade winds, and currents, for a considerable distance.
    Some storm.
    Remember that those who have sought to provide credence for contact
    between South America and Polynesia, such as Thor Heyerdahl,
    sailed/drifted west. They could hardly do otherwise.
    Much further south, traditionally beyond 40 degrees of latitude, there
    are prevailing westerly winds and currents, but that is a whole other
    box of dice ... Feel free to suggest that the Polynesians, in their 60
    foot double hulled vessels, deliberately sailed far enough south to
    make their necessary easting. After all, they did something of the
    sort in order to sail between the Polynesian heartland and Hawaii.

    Not just the meat, Lu, ya gotta consider the veg as well! Remember
    that the presence of Polynesian yams (of South East Asian origin) in
    South America has long been a mystery.
