Think long and hard
I have a 1998 model 170. It is a beautiful boat. Perfect size for one person to handle. Easy to trailer, to set up, to take down, to beach, to dock and to launch. However it is, as they say, "tender", i.e., a strong gust of wind will make you jump up to the rail real fast, or swim you will! I sail in Candlewood Lake, CT which has gusty winds that change strength and direction constantly and drastically. I have come close to being knocked down a dozen times over the past three summers. But it was not until last summer (2000) that it actually happened. Not dangerous, it all happened slowly. But the water was a bit too cold and the sky was cloudy, so I got real cold, real fast. The boat turned on its side then turtled (i.e., keel up) and there was no way to right it on the water. I had to take it (with motorboat assistance) to a beach where I removed the mast, etc., then righted the boat. What a pain, and my outboard was damaged. Since then, I have purchased from Hunter and installed a HobieCat mast float to prevent turtling (I would advise the same) and I have had a reefing point put into my main sail (I would advise the same). I also think the centerboard should have more weight. But Hunter has never gotten back to me on that issue although I have asked. The 170 sails fast, but it is not a "family" boat (as promoted), unless you use the motor exclusively. My wife and 8 year old daughter will no longer sail with me for fear of a knockdown and a swim. Since the boat is the right size and weight for me to sail alone, I am keeping it (for now) and making various modifications in the hope that eventually all will be well.
