13 Whaler would be nice, but you could buy another V20 for less money than a ragged out, motorless 13 Whaler. 30 hp isn't enough for a 14 McKee. If you're up for it, look thru Glen L's website and pick out something you like. Be a good winter project. The Ben Garvy's look easy enough, or look at the Simmons Sea Skiff if you are up for teh challenge
a couple of sites for you
