I will offer you a simpler experiment. Place your palm in the water and move it back and forth to create resistance. When moving backwards you will feel more resistance than when moving forward. This energy is taken from the water, it is its free thermal energy. This is explained by the effect of added mass. The asymmetry of the pendulum's oscillations, acceleration and deceleration, allows this to be used. I will need time to give a more detailed explanation, I can do this later.

Asked a few questions to the AI. Here are three excerpts:

“When atoms or molecules approach each other, the electron cloud of one can be polarized by the nucleus of the other, causing a temporary or permanent shift in electron density toward the more charged nucleus.”

“Even at significant distances, weak van der Waals interactions can polarize the electron cloud slightly, creating an asymmetry in the electron density distribution. This can cause the probability cloud to shift or deform slightly toward the neighboring atom.”

“By the Heisenberg uncertainty principle, the more precisely we know the position of an electron (i.e., its probability density), the less precisely we can know its momentum, and hence its kinetic energy. This means that in regions of high probability density, an electron has a large uncertainty in its velocity and momentum, which can lead to an increased kinetic energy.”

In my model, pendulums have greater kinetic energy and speed when passing opposite the nucleus of a neighboring atom, and this may be analogous to a region of high probability density according to the AI text.

In addition, if the orbitals of the model overlap each other, this will create a region in which pendulums will pass alternately, which gives a higher probability of finding them there and this may correspond to a probability cloud when the orbitals of atoms overlap.

Further, in the figure below, it is seen that in regions close to neighboring atoms, the orbitals are compressed and if we imagine the electron as a ball in an orbit, it travels a shorter path, which may mean its greater energy and speed. If so, then this corresponds to the model with pendulums.

In addition, orbitals can be considered as waves coming from the boat. They are also compressed (shorter) in front, in the direction where it is attracted, and expanded (longer) behind

Absolutely right, it happens. As you have drawn, the boat wags its hull like a fish wags its tail due to the displacement of the center of mass that occurs during the interaction of the magnets. 

No they can’t. These are 3D standing wave patterns, similar to the “spherical harmonics” you can excite by striking a rubber ball and watching its deformation with a stroboscope: 

 

And relying on AI in the way you are trying to is going to lead you astray. Don’t outsource your understanding to a bot.

Vibroboat hydrodynamics.

The phenomenon that makes the vibroboat move is poorly understood. And from what I know, the most in-depth study on this topic is mine. I posted it here more than once, but the topic was closed due to lack of confirmation. But now I was able to find two other studies that confirm it.

First, pay attention to the experiment in the video below. Here, the plate rises up and stops. At the same time, the turbulent vortex that follows it catches up with it and crashes, reflecting to the sides and expanding. This gives the plate an impulse.

https://youtu.be/GA2aj0JWuZA?si=1KPOQD9jG7fI1UH6

I can also provide a link to the Aerospace Engineering subreddit where this was posted here, so that you can see that no one denied it, but also did not give a detailed explanation. https://www.reddit.com/r/AerospaceEngineering/comments/1ak5m0s/can_anyone_explain_or_name_the_aerodynamic_effect/

The logical conclusion is that if the plate goes down at a lower speed than up, then the turbulence formed above it, and therefore the momentum imparted to the plate, will be less. And if we imagine a boat as a plate that oscillates perpendicular to the plane, quickly in one direction and slowly in the other, the resulting force will create a thrust in the direction of the fast oscillations.

In confirmation of this, there are two studies in Russian sources concerning vibration-based aircraft. Since access is via VPN, I have attached the article files below. A translator will be required.

Quotes:

“The experimental setup is fairly simple and is essentially shown in Fig. 1. This is a simple RL circuit in which the role of inductance is played by an elastic element (spring) L, and the resistance of the resistor is about 1 kOhm. The spring stiffness coefficient k=9.6 N/m, the attenuation coefficient of harmonic oscillations (the reciprocal of the time interval during which the amplitude decreases by e times) is no more than 0.005.”

“The following conclusion turned out to be more than unexpected. Traditional experimental data on aerodynamic drag coefficients are not applicable to describing oscillations of extended bodies. In this case, the oscillations occur with a drag coefficient almost six times greater than the C value obtained by blowing the plate in a wind tunnel.”

According to the effect observed in the video, each time the plate finds itself at the extreme point of oscillations, it receives an impulse from the vortex following it, which leads to an increase in drag compared to blowing in a wind tunnel.

On experimental aerodynamics of an
oscillator with an umbrella-shaped wing

The drag force of the environment, acting on one of the
bodies of the oscillating system, can create a
lift force. To do this, it is necessary to ensure
an asymmetry of the drag force. One of the
ways to do this is to use an asymmetric wing oscillating in the
vertical direction. There is an opinion that in this case the lift force
should be directed toward the convex
side of the wing. Careful experimental
study shows that this is not always the case.
The measured lift force created by a
cone-shaped wing is significant, but
in the opposite direction. Measurements of the energy losses needed to create
the lift force are in agreement with this
conclusion. It turns out that a wing moving
with its tip up forces the air to go
downward”

“The most important thing is that as the frequency increases, an
asymmetrical oscillator with the wing oriented with the tip up becomes heavier.”

My explanation is this: because the setup was suspended on a spring, the cone and the motor
oscillated as a single unit relative to the suspension, and as a whole they descended faster than they rose. Accordingly, the cone moved down faster than up. This asymmetry of oscillations created a thrust in the direction of the fast movement of the umbrella, i.e. downwards. The shape of the umbrella is of secondary importance.

My experiment clearly demonstrated this result. Two oscillators similar to the model oscillator were installed on the boat so that they compensated each other's rotation and led to a rapid displacement of the boat's hull forward and a slow backward.

This led to forward movement. The boat hull had a pointed nose like a cone, but when the engine thrust changed in the opposite direction, the boat moved with its tip backwards, which indicates that the shape was of secondary importance.
When moving on water, a corresponding wave pattern appeared - short waves ahead in the direction of movement and long waves behind.

This can be explained by the fact that behind the boat or plate a rarefied medium is formed, which does not disappear immediately after the motion stops due to its inertia. Instead, a sharp collapse occurs with a delay, with the release of free thermal energy of the medium in the form of directed movement of molecules in a vortex. The flight of birds, the movement of fish and many other flying and swimming creatures are based on this.

Many modern studies like this https://www.nature.com/articles/424621a
consider the flight of birds as a kind of jet propulsion, during which they throw off vortices, and this creates thrust. This is similar to the principle described above, and these vortices are impulses of collapse reflected from the wing.

My research on this topic was published in a non-authoritative, but still peer-reviewed Russian journal

https://sci-article.ru/stat.php?i=1601957819

In view of the current situation, I published an English translation here

https://doi.org/10.36074/2663-4139.17.01

In the end, in the Russian version of Wikipedia, the article Reactionless drive, in the section explaining the reason for the movement of this device, technically similar to mine, my edit was published, describing this principle of movement in a viscous medium.

https://ru.m.wikipedia.org/wiki/Инерцоиды

As for the boat with one rotor, its principle of movement is approximately the same as that of the boat with two. But it differs in more complicated movements due to the lack of compensation.

The picture below shows a diagram of a boat with a pendulum in two positions. On the left, the pendulum is removed from the magnet and has a normal speed V1 per half-turn. In this case, the force V1 is applied to the axis. The stator rotates in the opposite direction, but this is significantly compensated by friction with water.

On the right, the pendulum accelerates and slows down as it passes by the magnet. In this case, the average speed V2 on this half-turn is greater than V1. Accordingly, the force F2 applied to the axis is greater. The rotation of the body occurs in both directions at different speeds (the arrows are of different sizes), which is also significantly compensated by friction.

In the next picture, the pendulum makes a half-turn at a speed of V2, creating a force F2 applied to the axis. In this case, the accelerating magnet of the stator moves towards the accelerating pendulum faster than it follows it when it passes by and slows down. Therefore, the common center of mass of the system, marked with a cross, shifts with the greatest speed in the direction of the arrow TRUST. The force vector changes in time and therefore this arrow is bent. During this, an asymmetric vortex is formed, which gives traction. Accordingly, when the pendulum makes another half-turn at a low speed, this vortex on the opposite side is blurred and its force is weaker.

This does not contradict. An electron can be considered as a vortex. A vortex can also have the properties of a particle - have momentum and be reflected, being a structure localized in space.

A vortex can be described as a rotor with orbitals.

https://commons.m.wikimedia.org/wiki/File:Rotational_vortex.gif#mw-jump-to-license

And it can also be considered as a three-dimensional standing wave, since it has layers of different density.

In addition, a vortex can change its configuration like a harmonic as a result of external influence, like an atom at an energy level above the main one.

You can see all this here
https://youtu.be/oUSLfehZaIk?si=aaeyeMOh6tMoM44-

Although the vortex is not an exact copy of the atom, similar vortex processes such as toroidal fields and magnetic loops exist in electromagnetism and the vortex can be a manifestation of these fundamental forces in the macro world.

Regarding the AI text. I know that it can be manipulated. I deliberately tried to get from it the assumptions that I need based on the search results.
