I must admit that I have no first hand experience with these devices, but those that I have seen have the transom of the dinghy fixed one a couple of hinge-like devices to the back of the "mothership" and the bow free to move up and down. It seems that you would be placing a lever matching the length of your dinghy available for great forces of waves to pry the mechanism apart. I would think of these as only inland or protected water devices; however, as I said, I've never used or closely inspected these.
