The problem of how the Pacific was colonized against prevailing winds and currents is solved if we accept that the earliest path-finders had boats of similar design to the fast, long-distance single-outrigger with a tilting triangular sail, because these boats sail best a little upwind or with the wind on the beam. They must have had these outrigger canoes, otherwise they could never have made exploration probes and then colonized, and exploration is an easier proposition than subsequent colonization. For several reasons, the natural way to go is eastwards with the aid of occasional westerly winds.
