NOT LIKELY
Mike: I don't have a 23 nor am I anywhere near an expert on it or marine engineering/design. Having said that, you ask the same question my wife did when she first started sailing! Without going into any math (I was TERRIBLE in math!), basically, as a sailboat heals to the wind she gets more and more stable. See that for yourself by going out under bare poles sometime and motoring parallel to a beam sea and then put up the main. That healing, by the way, is what allows the boat to go faster...to a point. And that is the point. As the boat heals beyond a certain angle (around 20 degrees for my 31', probably a bit less for you especailly with a centerboard), the sideward force on the sails dramatically DECREASES. HUH? Yup, think of it (as I do!) in simple terms. As the boat heals, the sail starts "spilling" wind at the top decreasing the healing force and increasing the righting motion. At that point (all things being equal) the boats heal decreases until the next gust of wind hits it. There are a couple of things which could keep the boat healed. First, an extremely strong wind could put a vessel on her beam ends (we're talking gale/hurricane force here) or a large wave hitting the beam just as you reach max heal could throw the boat on her side. THERE IS VIRTUALLY NO CHANCE YOUR BOAT WOULD CAPSIZE IN ANY SITUATION WE NORMALLY FIND OURSELVES! (That is more for our new-to-sailing spouses than us). Since you apparently will be lake sailing in Texas, you probably won't have to worry about huge waves (except for those gigantic stinkpotters plying your waters!). However, thunderstorms are a real possibility (I'm an airline pilot and fly into DFW often!) so keep a weather eye, and reduce/furl your sails EARLY and I doubt you'll ever have a problem. I would recommend at least one good primer for you which has great sections on just about every aspect of sailing: "The Annapolis Book of SEAMANSHIP" by John Rousmaniere. I belive it has been continually updated and still in print. Mine was printed in the early 80's but I still refer to it. I hope this helps. Have an great time and welcome to sailing! Tim L.
