As you note, the H22 is the same design as the former H216, but in fiberglass. I suggest you review the H216 reviews. I've enjoyed my H216 for several years of day sailing on Saginaw Bay, which is somewhere between a little lake and the open ocean. It's a good safe boat, for its size, and rides well in a sea. I would not try to go out in something over 20 kt breeze or over 3 foot seas, nor be caught away from port if that were likely to happen. Personally, I would not sleep aboard for comfort reasons, but I've read of some owners that do camp out. The cuddy is very cramped, particularly after stowing your sailing gear. There is open space under the cockpit, but accessing it is for gymnasts only. There are some good articles in this site's owner modifications on upgrades, including installing flooring in the cuddy for sleeping. One issue is that the mast boot always leaks and there is no isolated bilge, so water does accumulate in a rain. Good luck.
