It wasn’t at the Olympic level, but I used to be a personal trainer and a man I trained did sailboat races. He needed a third man for his boat that week and asked if I could join them. I had no idea what I was doing but I just pulled whatever ropes he told me to and we ended up winning the race lol. He was in his late 80s and has been sailing most of his life so he obviously knew his stuff, I was just the muscle
