Sailing teams were not without challenges as the week of races have started for them in the Rio Olympics games. The US team in Rio de Janeiro had been preparing for months in order to get familiar with the tidal cycles and wind patterns in the Guanabara Bay. On the second day of racing the team experienced light wind that made it difficult for the races to begin. The early races in the five different categories were defined by tactical parameters that were treacherous. The races on the second day took place in the Guanabara Bay area.
