According to a local old sea dog, there is a 50 year cycle to the height of
tides superimposed on the usual new/full moon / sun distance, cyclic
variation.
If there is indeed such an influence , would any one know what it is -
earth's precession ?

Never heard of it; and if it existed I'd have expected to have done so.

It seems unlikely that it's the 260th harmonic of the Earth's
precession, or the third sub-harmonic of the Metonic cycle, or the
Jubilee cycle.
