Island Girl’s shortcut yesterday (in the region of South America known to geographers as the “Arica Elbow”, or "Arica Bend") took her over the Pacific Ocean for 371 km (231 mi) before returning to land in southern Peru. She appears to have made landfall in the vicinity of Ito, although it must be remembered that we have only a few GPS locations every day and the route that Island Girl actually follows to connect those dots is, by default, shown as straight lines on the maps but her exact route between the dots is unknown. For example, she might have returned to the coast considerably north of Ito and then followed the shoreline to Ito, and the map would look exactly the same.
By late morning today, Island Girl was on the move again, following the coast, and was 86 km (53 mi) from the Chilean border.
Here's an interesting article about the geology of the Arica Bend. Apparently the land north of Arica is slowly rotating counterclockwise, and the land south of Arica is rotating clockwise, resulting in the bent coastline (and the entire Andes chain, for that matter): http://www.sciencedirect.com/science/article/pii/S0040195198000584
