There are a lot of designs to choose from. Have a look at some of John Gardener's work. He has a book with dozens of plan sets in it, so the book price (not much) will pay for itself, the moment you build one. Chapelle has quite a few in his assorted books as well many others, some that specialize in just human powered craft. Though I'm not big on hand propelled craft, I have a few designs in this area too.
You should think about the build method, as some are more rewarding, then others. For example you can do a lapstrake build which produces, probably the best looking little boat, but the traditional method is tedious, with lots of steam bent ribs and plank fitting. On the other hand a glued lapstrake build can eliminate much of this effort, usually being sanitary of ribs all together. It all depends on what you want. In this vain, you might like the tedium, in which case maybe a strip planked build will satisfy or possibly a molded hull.
Check out Glen-L.com and Bateau.com and have a look at some of their traditional and non-traditional pulling boat designs. Refine your desires a bit, so you can narrow down the search.
