Find another place or get a mooring
As asked by another poster, why do you want to be in a place where you're going to be aground at least half the time? Equally important, you're going to be limited as far as when you'll be able to use your boat. How much are you paying for this?
How about a mooring in a deeper water with launch service? Usually a lot cheaper, btw... Slips near me run as high as $165/ft, cheapo marinas run as low as $85/ft but there's a long waiting list. The town marina is at the end of a loooong , skinny and shallow harbor for $54/ft -- not worth the inconvenience (location, location, location...).
If this is the least expensive option of several, you might regret saving a few clams at the 'cost' of risking damage and sailing a lot less. BTW, think about your hull when a storm comes in and she's rocking back and forth a lot more on her keel. Ouch.
