One day I was sailing, I was with a friend. We had a race in about ten minutes we were training a little bit when the wind changed and i saw his optimist sail changing direction(because the wind changed)and i lowered my head, fortunaley none of us got hit, sadly I ended up in 3 place
Another day something similar happened we were still in land but the optis had the sails on, the wind changed directions and all sails changed of place
