All our previous boats (multis) had half tide moorings so dried/lifted twice a day for 6 months of the year for 10+ years. They were on soft mud and stones. There are 2 issues.
Abrasion of the hull/antifouling you can prevent by using keel
shoes and a hard antifouling such as coppercoat (epoxy/copper) otherwise live with losing some antifouling. We did neither and had no real problems except that by the end of the season we got fouling in those areas rubbed clean.
Pounding. If the bottom is hard enough and the area subject to any swell/waves then the boat will pound and eventually do structural damage. If you have ever been on a boat drying on hard sand just once you will recognise the problem. We occasionally would dry out on sand when cruising in sheltered areas in benign weather
and the whole boat would shake/thud heavily for a period while taking on/off. In this, soft mud is your best friend, we never ever felt the boat take the ground or lift
off on our mooring
