These are sailors who in the darkness, in the hull of the vessel, can distinguish as many as 32 different sea swells moving through the canoe at any one point in time, distinguishing local wave disturbances from the great currents that pulsate across the ocean, that can be followed with the same ease that a terrestrial explorer would follow a river to the sea.
To su mornari koji u tami u koritu broda mogu razlikovati do 32 različite vrste bibavica koje se kreću uzduž kanua u bilo kojem trenutku, razlikujući lokalne valne smetnje od velikih struja koje pulsiraju diljem oceana i koje se mogu pratiti s istom lakoćom s kojom bi istraživač na kopnu slijedio rijeku do mora.
