I would think a Flying Scot with a furling jib would be great for you, or a Buccanneer. If you swim while sailing these boats, you need to re-consider sailing. I also would really think your wife could help with jib sheets - couldn't you ask her to release that one and pull on that one? She might enjoy sailing on a more "lively" boat, ymmv. For a keelboat, in addition to those mentioned, how about a Sweet 16.
