Habitatpro,
I've seen a single 6 x 6" post set into the ground about 16' from the bank and extending 3-4' out of the ground. The post had a standard boat winch from a boat trailer attached to it. Pull up to the shore, hook up the strap, and yank her out of the water and pull the plug. It would take a little elbow grease to shove it back in the water,, but I suppose you could fab a small "rail" system with rollers (as opposed to bunks)that lies on the ground. This would make it easier to winch up and a breeze to launch. I use rollers on my trailers with the larger boats because we rarely have a boat ramp. Makes life easy.
