For several of our disabled dogs we have made either a platform or sling to allow them to get ashore. The Garheur davit works well in the C Dory-- One way is to use a piece of 1/2" plywood the same foot print as the dog lying down. Pad this, then cover with Sunbrella, and monel staples on the bottom. Make webbing steps which cross cross across the bottom about about 2 feet above the platform. Then take another pice of sunbrella about a foot wide, stable on the bottom, tack to the webbing, and leave an overlap on one end (double flaps, but not attached at the very ends. Us velcro to attach when the dog is in the sling. The dog walks in, lies down, and then you bring the flaps around the entrance so the dog cannot fall out. Hoist over the stern, and deposit the dog on shore. Then the dog gets up, goes about his business, and comes back to the sling. Sort of like a bosan's chair for the dog--you will understand bing an old sailor!
