David,
Good evening. I am building my second Core Sound 17 MkIII. I sold my first boat, tried a Precision 18 which was a disappointment, so now I am building a second boat. My daughter is building a pocket ship. It has been a slow project for her due to work. It seems like a good kit. It does not have the room of the Core Sound. My wife and I like the Core Sound since it feels very secure, stable, and manageable in a variety of conditions. Our other boat is a Wayfarer Dinghy. The Core Sound is the boat we sail to relax and to do over nights. We don't want to conquer the world, just get away from it for a while. I am biased but I think with good reason. I hope this helps. If you have questions please ask.
Regards
