Unfortunataly that kind of thing happens, 911 for examaple. You just have to convince the sponsors that if that happens, (a race gets cancelled)you will make it up, Do two more boat shows, or 5 parades. The best thing is let the sponsors know that at the end of their sponsor year, you will give them a list of where the exposure was. They can't read every news paper and every magazine, but you can because you know where you were and what mag. you will be in. It is tough, but it can be done. Good luck to you.
