M_Boats: Anyone have any experience with an RK20?

Hi All: Does Anyone have any experience with an RK20, good, bad or otherwise? This is another Lyle Hess design. There's one for sale here (it was my #2 choice after my Monty) and I've got a friend with a SERIOUS sailing jones but very little money, and I'm steering him towards it. I think it's in bad shape, no trailer, but I think we can fix it. Best BG
