Depends
Hi Cindy, its not likely to happen under the conditions you described. Its usually the result of a wave-train, out of sync (large rogue wave), that causes the boat to fall off the wave at the exact moment a massive gust of wind heels her over and a large boarding wave fills the cockpit, causing a shift in the centre of balance. In other words conditions that one should not be out in unless caught out by mistake. The righting moment of your boat is probably about 100 degrees, meaning the boat will right itself (theoretically) with the mast 100 degrees over from the vertical. Picture what that looks like in your mind and you may conclude you were a long way from that. Its more a feeling of pending doom that we all must learn to overcome. What you described with the rudder was the result of severe weatherhelm which caused the rudder to act more like a wing rather than a rudder, causing the boat to round-up into the wind. This is a good thing as it helps the boat recover from excess heeling. You may have had too much sail up, better to reduce sail and keep the boat on its feet. Sounds like you have rediscovered the fun of sailing, and in a good boat too. Have a blast. Don
