170 stability
I'll just throw my two cents in belatedly. Before I bought my 170, I read the comments about stability and was worried about the boat going over, turtling, etc.I contacted about twenty 170 owners, heard back from most of them, and all but maybe one considered the stability fears to be overblown.I've come to feel the same way. If you sail within your ability, this boat is actually quite stable. It is true that it is very responsive, but frankly that just makes you become a better sailor.Alsough I've sailed in winds as high as 15 mph, I generally find winds of 10 mph or less to be most enjoyable. I personally don't worry at all in winds up to 12-13 mph. And as long as you have SOME wind, this boat can ghost around nicely in the most gentle of breezes while others are reaching for the motor/paddle.Last year, my youngest was at the helm and we got hit during a tack with an unexpected gust....to make matters worse, my son had forgotten to uncleat the main. We did a complete 360, with all three of us diving to the center and my oldest quickly uncleating the main. During our first year with the boat, we made some dumb mistakes under stiff winds as well. In none of the cases did we go over even though I was sure we would.Not to say that the boat can't go over, and I have the Hobie float on top as insurance, but I was a Nervous Nellie before getting this boat and I now know that much of the fear was vastly misplaced. Again, as long as you stay within your abilities, sail within reasonable winds (and reef when necessary) there's no reason at all to be worried.
