We've just finished up a GREAT first season with our '76 O'day 25. Having previously only sailed much smaller boats, I was perhaps very much overly cautious and conservative about heeling (Usually not heeling beyond 15 degrees). Anybody have thoughts on what the safe limits are?  A family friend who's a serious sailor (and former math teacher) has offered to run stats on the O25 with a couple of different formulas. In order for him to do this, he needs the following:1) Angle of heel for max. positive stability (max. righting area in feet)2) Angle of heel for min. positive stability (zero righting area in feet -- rollover point)I was able to locate all the other basic info. I needed here.... --- thanks!

Heeling

I can't answer your specific questions, but I will offer my experience on my 78 O25. 15 degrees is not nearly too much, but the boat sails fine at 10-15 degrees. Beyond that, you loose speed for various reasons that have been discussed on this list in the past. I've sailed at 20-30 degrees when I've been out with friends who want some action, but the family prefers 10-15. I've been almost knocked down a few times and the boat came back up without a problem (other than my heart stopping).I'm interested in your friend's calculations. Let us know what he comes up with. Sorry I can't give you the specific information, but I'm sure someone here can.Alan

What I know, What I've heard

I too have a '76 O'Day 25 (centerboard model). When I'm out for having fun, I regularly sail it up to 40 degrees. At that point, it will typically turn to upwind. 20-30 is absolutely no problem. However, as reported, it really sails best if it's kept to about a 15 degree heel.I also had a report first hand from another O'Day 25 owner (also a '76 CB) that he got hit by a sudden gust, the boat heeled over to 85 degrees, put the spreader in the water for about 10 seconds, and then it popped back up.
