string of seven or more islands in a line running north–south (which historians generally agree must be the modern Ragged Island, Bahamas) before landing on the north coast of Cuba. A successful inter-island track must therefore navigate from Guanahani to the Ragged Islands in a way that fits the descriptions of the log without serious infidelity. Strictly speaking this is impossible, as there are a few places where the log seems to contradict itself. Island II Leaving Guanahani late on 14 October, Columbus said "I saw so many islands I did not know how to decide which one I would go to first". Aiming for the largest, he estimated its distance by eye at five leagues, while other islands were both nearer and farther than that. He arrived at Island II around noon, delayed by a contrary marea (usually translated as "tide", although "breeze" is possible), re-estimating the distance as seven leagues rather than five. Island II had a coastline facing Guanahani that ran north–south for five leagues, and another coastline ("which I followed", says Columbus) that ran east–west for more than ten leagues. At this point comes a contentious passage in the log: "And since from this island I saw another larger one to the west, I spread sail to go forward all that day until night, because [otherwise] I would not have been able to reach the western cape of the island". From this it is unclear whether the "western cape" at which Columbus anchored that night was on the island with the five- and ten-league coastlines, or the larger island to the west; in other words, it is unclear whether Columbus was adjacent to one or two islands on 15 October. Those who prefer the two-island interpretation call these Island IIa and Island IIb. Island III The log gives two descriptions of the sail from Island II to Island III on 16 October: in the first version, Columbus leaves at 10 AM and sails nine leagues east–west to reach Island III; in the second version, Columbus leaves at noon and sails eight leagues "almost east-west" to reach Island III. Columbus also gives somewhat contradictory information on the size of Island III, saying at first (before actually exploring the island) that it "may well be" more than 28 leagues long; but later saying only that "I saw quite 20 leagues of it but it did not end there."
