Sorry I have come to this so that but just in case anyone else reads it. I own a Leopard 42 and used to keep it in the UK in the Bristol Channel. You have to dry out here as the tidal range is the second highest in the world.
No problem at all drying her out, and we never experienced any issues with pounding, she sits down quickly and easily. Usually we where on a
mooring with fore and aft lines but we would do the same thing with twin anchors. The rudders and propellors are always well clear.
The only thing to be aware of is that if you are on sand that is reasonable firm she will lie bow down (because of the design of the keels) so if there is any slope then you want to take advantage of it. On mud of course it is not a problem. I think the idea is that you would go bows onto a beach
