As I recall
it was a decent anchorage (both were), but it was some time ago and I don't really recall
what the bottom was like. I don't remember any drama around finding a spot and getting the anchor
set, and I certainly recall drama in some of the anchorages
along that coast.
However, the old coast pilot has the opposite opinion (possibly from the point of view of much larger vessels):
Corrales Harbor - West of Tabo Bay, separated from it by a high hill is the so-called [sic] harbor of Corrales, the western limit of which is only about 1/2 mile from Cape Corrientes. It is about 1/2 mile in extent, but affords no convenient anchorage because of the depth of the water, 30 fathoms being found in the center and 4 fathoms within an oar's length of the beach all around.
A sunken rock, on which the sea breaks in rough weather, lies off the mouth of the harbor, about 600 yards from the shore. A good landing may be had in this bay.
My memory is that we found a decent spot along the east shore near the village. There is a charter
cat that says this about it:
Corrales is a fine protected inlet just inside the Southernmost tip of Banderas Bay. It’s where we can securely drop anchor if we want to stay overnight near Cabo Corrientes, which we must go around when we’re on the longest leg of our Costa Alegre Discovery cruise. It saves a few hours time and is convenient when we’ve been enjoying the South Coast beaches and lively water environments during the day and we want a nice quiet, calm anchorage for the night.
