Wind can't capsize the Oday 25
38% of the displacement of the centerboard Oday 25 model is lead ballast. The worst that the wind can do is to knock the boat flat (down to 90 degrees.) And the lead in the keel will always bring her back up when the wind eases. Even a knockdown is a rare event. In listening to experienced sailors, less than one in 30 years of summer sailing is my estimated frequency.
The Oday is a ballasted keel boat, even if it has a centerboard. The only way it can capsize is if a wave 9 feet high or more hits it broadside. And it takes hours for the waves to build up to that height - plenty of time to get off the water!
Capsizing is common in unballasted boats, where the only ballast is the weight of the crew on the rail. For such a boat, (a Sunfish, for instance) the first drill is to tip it over, and practice righting it, and getting back in it.
I think sharing this fact is some help, but I do agree with the suggestions of lessons, and more time sailing with a trusted captain to reduce the real fear of heeling.
Falling out of the cockpit in the rare event of a 90 degree knockdown is a reasonable fear, and a good reason for PFD's and (when called for by the weather possibilities) harness/tethers.
