The ebb and flow is the result of the rotation of the Earth and the gyres

To calculate the height of the tides in the Bay of Fundy, you need to know the speed of the whirlpool and the depth of the Gulf of Maine.
If anyone has this information, please write them.

So what is the purpose to all of this whirlpool theory?

For reference: "Tidal forces in nature - the statement that the center of the Earth is less attracted by the Moon than the surface of the Earth due to remoteness." The degree of heterogeneity of the gravitational field of the Earth depends on the distance from the Center of the Earth to the Earth's surface. And the larger the radius of the planet, the greater the heterogeneity of the gravitational field.
If tidal forces existed, then the pressure of water and air would certainly react to this, especially during the parade of the planets.
Darwin and Laplace scattered with their research the conviction that the Moon influences the barometer with its attraction.

It is believed that the maximum tides are formed in the new moon and the minimum tides are formed in a quadrature. Has anyone tested this? (Minimal tides are formed in a full moon)?

Yes, very easily observed at places with large tidal ranges, we have about 5-6m range, springs and neaps are obvious.

Fermer05:
Fluctuation of the amplitude of tides during the month is a rather complex phenomenon of nature and it will be rather difficult to explain it without a model of the solar system.
This is due to the oscillation of the orbital velocity of the earth, and the complex trajectory of the earth's motion in orbit, because of the barycenter.
And further.
The center of the earth can be imagined as a material point that moves in orbit at a speed of about 30 km / s, while the Bay of Fundy revolving around this point at a speed of 1,700 km / h, moves relative to the sun, then forward and backward, then tops downwards, which adds additional complexity.
