Day 4, the penultimate racing day of the 2017 South American Championships at the San Isidro Sailing Club in Buenos Aires. The sun has returned, competitors are eager to get going, working their sails hard, and wondering what today will bring.
Peruvian coach, Juan Carlos Gonzalez, explained: "Each day it changes, today we have wind, the current, the sun; yesterday we had rain; we get a lot of wind, we get no wind - it depends on the day, the time, always different. It is not an easy place to sail, very hard. The locals are always in the front, you have to try and catch up with them!"
