About 50 cats got turned over in the big Mt. Dora spring race back in the day. The start was scary downwind blowing over 25, then it got way heavier! My Hobie 18 didn't just capsize after the first mark while missing others, it got flung upside down, and the mast stuck in the mud. It took us 20 minutes on one hull then the other trying to get it loose. On the way back in, the same thing happened again, and it took a powerboat to get the mast out. Nobody got hurt AFAIK. Yup- cast iron.
