Bucky, that's called careening
a boat and it is the traditional way to clean a bottom.
Couple of cautions: Put out a radio
call (securite) beforehand, if folks see a boat "on the beach" they may call into the coast guard, who will appreciate knowing to ignore this.
And some folks would recommend putting a number of used tires, etc. between the hull and the beach, to prevent chafing and other damages.
How politely the boat goes over, whether the keel hangs, whether you need some lines to encourage it...all things to consider. And to make sure the deck
won't take water when the tide comes back in and she refloats.
Careening is out of fashion, hauling certainly is easier and faster, but for hundreds of years careening is how it was done. Your local yard may be willing to give you a good rate on a "lunchtime haul", where they haul you before launch break, and drop you back in the water an hour later. That's often time enough to clean the bottom, and a deal can be made.
