explanation_1: People yachting could be anyone and don't have to be rich aristocrats
explanation_2: Four men riding in a gray, fast moving boat appear to be wearing vests doesn't imply that a group of rich aristrocrats are yacthing and are annoyed.
explanation_3: Just because four men riding in a gray, fast moving boat appear to be wearing vests does not mean they are rich aristocrats and are annoyed.
