In New Zealand, there is a tidal power plant.

That is not an excuse why your theory fails.

If the NZ government completely dammed Cook Straight for a tidal power plant, then that would slow the current considerably. But they haven't.
- In fact, if they did this, the current would slow, but the tidal range would increase, the opposite of what your theory predicts.

I think you have confused correlation and causation:
- many of the world's tidal power plants are built into estuaries or bays which have both a large tidal range, and a high current flow
- But this does not mean that the high current causes the large tidal range.

The only way to refute the whirlpool theory of tides is to name the coast where the current is moving fast, but there are no high tides there.

What about Cook Strait, in New Zealand?

I've given a counterexample.

You now have to explain why it doesn't refute your theory.
You quote a speed of 7 knots for the Cook Strait. How does your theory predict the relatively low 2m tidal range?

It's no validation to say "It depends on several other variables that I am not going to define".
- You have the location
- Now, calculate the he size of the gyre, the amount of water under the gyre, the distance from the coast to the gyre
- At least I can help you with the direction of the current - it is basically East to West, and West to East slightly over 6 hours later.

The tide height is shown here (in Russian).

The interesting thing is that just outside Cook Straight to the west (where the current is small), the tidal range is shown as dark grey (ie large).
- But inside Cook Straight (where the current is large) the tidal range is small.
- This is the opposite of your theory.
- Your theory does not work.


PS: I sailed through Cook Straight in January 2019.
- Fortunately, I was not the one doing the navigating!
- I assume the navigator timed it so it was high tide in the East (where we started), and low tide in the West (where we were going), and they cruised through with minimal engine power.

A “lunar tidal wave”, moving from the Indian Ocean from east to west, crashing into the eastern coast of Madagascar creates tides 1.5 meters high and abnormally high tides 7 meters high, for some reason they form in the west of Madagascar. Wikipedia explains this discrepancy by the reflection of waves and the fact that the Coriolis force does its job.
And the real reason for this discrepancy is the giant cycle, rotating around the island of Madagascar at a speed of up to 9 km / h, precessing, reflecting the tidal wave towards the western coast of Madagascar.

To predict the tides, you need information, a map, the current velocity, the depth of the coast.
You have chosen a very inconvenient place, choose another place where there is a flow map.
For example, the island of Madagascar.

To predict the tides, you need information, a map, the current velocity, the depth of the coast.

You also need detailed information on positions of moon and sun.

You have chosen a very inconvenient place, choose another place where there is a flow map.

By inconvenient you mean it doesn’t support your hypothesis 
Try the English Channel.
One of the most charted and sounded areas in the world with detailed records and accurate predictions of tides and tidal flows.
Even a very brief look at the charts and almanacs shows that your hypothesis is seriously flawed.

This has all been explained to you previously and you either do not understand it or are deliberately ignoring the information.
Because of the danger to life posed by someone following your flawed ideas, these threads are being locked.
