I just bought a 1984 Nacra 5.2 a few weeks ago and it works well with my wife and two kids. Well, actually my wife hasn't got on it yet because of the third youngest boy. I take my 7 year old daughter and my 5 year old son on it all the time. We went out today and it was blowing between 10 and 15 mph. It was a little more wind than I would have liked with the kids so I sailed with just the main. My daughter is special needs and is usually just along to enjoy the water. My son however is very handy when someone needs to go to the leeward side to raise or lower the daggerboard or the rudder. The boat got powered up a couple a times and I accidentally flew a hull. I don't like doing that too much with the kids on. It is a very stable boat compared to the H16. I turned the tiller over to my son so that I could go forward to take some pictures. He got too busy hamming it up for the camera that he pulled us into an accidental jybe. I had to drop the camera and do some serious scampering, but the boat never even lifted the hull. Thank God for water proof cameras and safety halyards. The Nacra is very forgiving... so far. There are a lot of lines and trim points on the Nacras, but most can be locked out or you can use them all to fine tune the sails. It is IMHO the most well rounded boat I have sailed so far. My experience is limited though to the Hobie 14, Hobie 16, Apollo 16, and the Nacra 5.2. I don't recommend the H16 because with a second adult onboard, it will want to PP anytime you get your speed up downwind. I weigh 150 pounds wet, so I wouldn't be able to right it solo, but I wouldn't be able to right an H16 either, so I went with the better boat. I could right the H14, but that is not enough floatation for two adults. I plan on installing a soloright pole eventually. For now I will just sail it on the light/moderate days. I hope you find a good boat for a great price. Be patient... your boat is out there somewhere.
