Some of us sail boats without enough deck space for a dink, and I hate inflatables!
Have you ever considered rail mounted davits? The advantages of lifting your dinghy out of the water include reduced drag and ease of launch. Many quality rail mount davits are also able to rotate and be easily removed. Some davits also have an adjustable height and reach to get past windvanes or other structures.
The price and commitment that davits represent far outweigh the risk, cost and the catastrophe that losing your dinghy just once would produce.
