I want to install a fixed mooring this summer and see that for example
mushroom anchors are expensive.

The environment is... Atlantic salt water, in a fairly well protected
cove, with 6' tides, in about 10-15' of water, virtually no traffic
and a spit serving as immediate breakwater.

Alternative suggestions to a mushroom would be appreciated.
