This paper presents a new geometry of the western Pacific based on an analysis of the time necessary for canoes to sail to islands around S amoa. Using methods proposed by F rancis G alton in 1866 and 1881, updated by a computer simulation of sailing trajectories, the author demonstrates the existence of a navigational threshold east of S amoa through systematic ‘displacement’ of islands according to sailing time in winter and summer – a threshold that helps explain the ca 2000 year pause between the L apita era settlement of M elanesia– W est Polynesia and the settlement of E ast P olynesia.
