Meanwhile in the real world the non-existent Bayraktars continue to cause trouble. Two Russian boats
have been sent where Russian boats tend to go:
...
If you watch a longer,
2-minute footage, you can see that after the strike at the end of the video, the boat didn't sink, but continued to swim.
Is there any evidence that these boats sank afterwards?

Is it known how thoroughly the AP studied the version with an explosion inside the building? What experts do AP rely on?
The Russian side cited the opinion of
Vladislav Ivanovich Telichko, the former Deputy Minister for Emergency Situations of Ukraine, who refutes the airstrike version. According to him, the explosion was carried out inside the theater.
Video with his commentary:

01:50 - "Here's another interesting point. This is a fire hydrant. If the explosion had been a little higher at this level, then these articulated joints and everything else would have been deformed or, most likely, even destroyed. But since there were several storey mates and a load-bearing wall, they closed this niche from below. Above us is a roof. If there was an explosion from above, then this swivel would not function. According to this picture of the explosion, the explosion was clearly under the lower layer of reinforced concrete base, on which there was an auditorium and the stage itself".
03:14 - "You see, what I said. There was a third floor, and this is the first floor. The lower, the greater the deformation, much stronger and more. That is, the epicenter of the explosion was under all structures".
04:17 - "The reinforced concrete slab was completely destroyed, and it all went down. The explosion was from below".
Pro-Ukrainian individuals may accuse Vladislav Telichko of bias or subjectivity, that's why such high-profile events should be investigated by independent experts who are neutral towards both sides of the conflict.

Under this video, one user left a comment, that it was a Russian retaliatory strike on a Ukrainian howitzer.
A translation from Russian to English
Svetlana Vakulenko: "Kharkiv News should also tell that it was a response from the Russian Federation. Maybe someone will tell why it was necessary the AFU show themself first - from a self-propelled howitzer in the direction of Zhukov, in the area of the park, along Novgorodskaya st. (traces of caterpillars on the street are difficult to remove) - and then catch the answer? There are enough witnesses of the shooting of the Armed Forces of Ukraine from Novgorodskaya. A big thank you to the public utilities and firefighters for their work!"
Looks like this user was talking about the northwestern part of the park:
