Orcas have sunk 3 boats in Europe and appear to be teaching others to do the same. But why?

I think the orca can hear the humans interacting in a sail boat they don't like human noises because they aren't the same specie and are foreign to their habitat. Like territorial protection for their water. They are saying we are the largest and most aggressive and we eat white sharks livers just for a snack.

Scientists think a traumatized orca initiated the assault on boats after a "critical moment of agony" and that the behavior is spreading among the population through social learning.

Many sailboat owners have been installing acoustic antifouling devices to the inside of the hull. They emit powerful high frequency sounds 24/7. Some devices hop between different frequencies. The frequencies they use are above the human hearing threshold, but well within the hearing range of many marine mammals (there is a wide range of potential problems for marine mammals caused by anthropogenic noise pollution). Although the device is inside the hull, the hull effectively acts as a huge soundboard coupling the acoustic waves directly into the water. We first noticed such noise sources in a UK marina a few years ago (2018) so it's possible that they are quite prevalent among the worldwide sailing community.
A question to the journalists and scientists regarding these documented cases of Orca aggression - did these vessels have the anti-fouling acoustic devices fitted and active at the time?

If it were frequencies and exhaust I'd expect them to go after powerboats instead of sailboats. It's intriguing.
its important to note that , regulations and restrictions can vary based on different factors, including jurisdiction, local laws, environmental considerations, and safety concerns.

Powerboats generally have engines that produce more noise, emissions, and turbulence compared to sailboats, which might be one of the reasons why regulations are more focused on them. The higher engine power and speed of powerboats can create more significant impacts on the environment, water quality, and wildlife habitats. Additionally, noise pollution from powerboats can disrupt the peace and quiet of recreational areas or residential areas near water bodies.

Sailboats, on the other hand, typically rely on wind power and do not have engines or produce as much noise and emissions. They are considered more environmentally friendly and quieter compared to powerboats. As a result, regulations and restrictions may not be as strict for sailboats in certain cases.

It's important to remember that regulations and restrictions can vary greatly depending on the specific region or water body in question. Therefore, it's always recommended to consult the local maritime authorities or governing bodies to understand the specific rules and regulations that apply to powerboats and sailboats in your area of interest.

So why no reports of Human Hating Orca Whales before 2020?
btw -
Star Trek was not actually filmed "On Location", contrary to what Mommy told you.

Your response to his answer is way off. His answer was to the poster before him that commented maybe it was the noise and pollution from the boats that caused the attacks and had nothing to do with Regulations, Maritime Laws or Governing Bodies. Perhaps having the brain in gear before letting the clutch out on the mouth.
