I see  your point.

The  ocean tides are coupled driven damped harmonic oscillations  of many
ocean basins and various seas -- large and small.  There are several  tens
of driving frequencies which produce many tidal components -- the NewZeland
site says that they consider some 700!!!  NOAA  usually considers some 70.

The end  result is that there is not much correlation between the _several_
Moon frequencies and local tidal frequency ie  high water does not occur at
a constant regular  interval -- I would like to say "anywhere" but I
don't  really know that  that  is precisely true.
The NewZeland site  plots the main Moon component, M2.

However, in addition  to the above, you are quite correct  that there is --
again  I would like to say "never" -- a correlation  of the position of the
Moon with local high water.
