Lunar phase and tidal waters

Hi all.

Around here, the term "good friday's ebb tide" refers to the belief
that
the sea level on the low ebb on good friday (which happen very close
to the full moon) is particularly low. This good friday, there were way

more people along the beaches than normal, which got me thinking.

The question is: While there is a significant difference between
the tidal levels between full and half moon (the high tide is
significantly
higher and the low tides are significantly lower at full moon than at
half moon), are there any tidal differences between full and new moon?

The gravitational pull of the sun and moon work colinearly but in
opposite directions at full moon. They work colinearly in the same
diraction at new moon.

Is this difference significant?

The tides is *no* different with Full Moon or New Moon. The tidal bulge
is equal on the backside where the Moon's gravity is weakest.
