> “It is a rare behavior that has only been detected in this part of the world,” said Alfredo López, an orca researcher at the Atlantic Orca Working Group (GTOA), in an interview with Scientific American last year.

They also recently rammed into a yacht near Scotland, and in British Columbia an Orca collided a yacht into another yacht by dragging the anchor chain.

I don't know how rare it is either, but it's not unprecedented. There are lots of old sailor stories about aggressive whales.

What I saw in other reports that I did not see highlighted in this article is that the whales aren't just deciding to sink yachts, but appear to be teaching each other.

Personally, I have my fingers crossed that they can learn to target yachts specifically.

"I have my fingers crossed that they can learn to target yachts specifically."

"Yachts" here look like moderately sized sail boats. Doesn't look like this is rich people's super yachts if that is what you are getting at.

The definition of yacht is loosely a boat for personal use that is suitable for multiple day trips.

Right, the response will obviously be to do nothing/protect the whales.

(I'm being sarcastic, they'll get slaughtered)

Big incentive to learn the language I guess, so that someone can explain how one sided the situation actually is.

It probably all started with somebody in a yacht flushing their toilet in that part of the sea.

I can imagine somebody is sharpening up their harpoons somewhere.

I'm remembering that orca attack was one of the seemingly fanciful explanations floated to explain the disappearance of Jim Gray and his boat near San Francisco years ago.

Would be almost ironic if this were true. (An eminent CS pioneer falling prey to a whale R&D project decades before they took it mainstream.)

You get that you can buy a sailboat "yacht" in europe for 1000 usd right? Or even get one for free. Plenty of people sailing are not rich.

There was a YouTube video showing tracked wales trying to cross an ocean. It also visualised ships crossing the same ocean. There was so much traffic that the wales kept having to turn back and turn back. In the end being unable to find a gap in the “traffic” to be able to make the journey across.

I feel this may partly explain the motivation to take a few ships out that fall within do-able for them.

Can they not go under the traffic?

If I recall correctly, the issue is noise, not the physical footprint of the boat.

Here's the visualization: https://www.youtube.com/watch?v=4qNO6JaL9PY

Ahhh of course, thanks. What a dolt I am.

Oh I didn't mean that, it don't think it's at all obvious. I thought your question was reasonable.

I was genuinely thanking you! As soon as I read your answer I thought "oh, that's incredibly obvious, I should think more before posting". Hopefully it all helped someone else anyway.

I still don't understand - what is it about the noise that prevents the whales from crossing it? Do they confuse the noise for an active predator, or does the noise prevent them from navigating properly with their echolocation?

I'd guess it's interfering with their communication and internal mapping in myriad ways.

As susceptible this news story is to humorous takes, I worry that this may soon affect honest seamen and others aboard vessels 50 feet long and below. Or is it happening already but it’s not being mentioned because the yacht stories are juicier? This is troubling.

We could use AI to ask a captive orca what they think about this matter.

Do you think one can use AI to help humans build some common sense? You seem to need it badly.

What in the world are you talking about?

That's like asking someone from an unconnected tribe why kids are doing stupid stuff on TikTok.

“So long and thanks for all the yachts”

My first thought was that the derogatory name for Russian invaders has somehow become mainstream...

Orcas are not orcs, orcas have a biological nature.

It's just that sometimes orcas don't like yachts :(

This is explainable and understandable at least.

> My first thought

keep up the good work. /s

shocking. wild behavior seen in the wild.

There is a reason they are named Orcinus Orca...

Hard to believe not that long ago that they use to help us hunt whales. https://en.wikipedia.org/wiki/Old_Tom_(orca)

People who take a yacht in the middle of the unforgiving ocean without a ranged weapon to dissuade pirates or rogue sea life aren't just stupid but a liability since they waste taxpayers' money when they have to be rescued because they chose to be unprepared.

You get that strait of gibraltar is so small you can see the other side right? So hardly middle of the ocean to sail your boat when you can see land on both sides with your eyes.

How would you prepare against orcas?

> You get that strait of gibraltar [sic] is so small you can see the other side right? So hardly middle of the ocean to sail your boat when you can see land on both sides with your eyes.

Not sure what this was supposed to say, but it appears to be a red herring.

Proactively: Design and build yachts that are more robust to blunt impact.

Situationally: Hunting rifle or speargun.

Extra points if we eventually find out that someone is communicating with the whales, putting them up to it with promises of fish : )
