It can be tricky absorbing the nasty chop you get with decent wind in shallow
water.
Moorings do not help with this.
The notion of laying (semi-permanently) a decent sized anchor (eg 50#) with a decent length of rode is more appealing to me, but there's still a problem:
When it's shallow, chain catenary doesn't help arrest the snubbing, either at the boat or at the anchor, and the elasticity of a nylon rode is a double-edged sword.
Chafe (external damage) is one problem, particularly where the rode comes aboard, and internal deterioration of the rode (due to heat generated by repeated stretching) is another.
One possibility is to use all-chain, with alternating floats and sinkers attached along the rode at intervals*. The one nearest the anchor should be a heavy sinker, and the one nearest the bow should be a large float. When you are not on the mooring, the large float will act like a mooring buoy for pickup: it should be large enough to hold up under the weight of the remaining chain.
This makes a very "soft" action, but durable rode, which will continue working reliably despite long unsupervised periods. You can use discarded (preferably aluminium, but failing that, galvanised) LPG bottles for floats.
*Don't make all the intervals the same ! (possibility of resonance)
