Re: Grounding on purpose
There is a practice, most popular in places with extreme tides, called "careening" a boat, where you tie it up at high tide, let the tide go out and work on it when it is high and dry. In England quite a few moorings are dry at low tide. The safety for the boat will depend on the balance of the boat and the underwater configuration. It will rarely be safe for the boat with a fin keel, better with a full keel, but the ability to do this is the reason that twin keels can be found on some English boats. Some boats with lifting keels and twin rudders are designed so that they will be stable if left dry, though in every case you need to be certain that the bottom is smooth and level. If there is a either a boulder or a hole under the keel or rudder, its a major disaster. In the US you dont hear of people doing this very much.
