There is an advantage to drying out a hull, it saves the environment as you usually don't need anti-fouling paint which can be be fairly toxic. The organisms can't stand the alternating air and water environment so you don't need to discourage them.
My father kept his fin keel boat tied up along the harbour wall in Ramsey. The tidal range was more than 10 metres (30+ feet) and so the harbour driued out completely, except for the residual Sulby river flowing through the middle. He added a leg to the off side which helped support the hull, as did the two or three boats often rafted outside him which all leaned against each other to a greater or lesser extent.
Here are a couple of pictures stolen from the internet which show the effect of tidal range. The top picture is not quite high water and is taken from further up the harbour, the lower one is low water at the harbour mouth.
