Orca attack

Well, sort of.

Never been on one.

I’ve seen very small animals attack much larger ones, so my question remains but has not been answered directly but slightly with ridicule. What was the post above about commercial vessels attacked (that my browser will not open)?

I know the whales travel the same routes as small fibre glass sailing cruisers.

I know nothing of passenger cruiser rudders. Big metal I guess?

I have read low frequency radio waves scares or disrupts whales. Submarines use them for comms. So I read…

VLF radio waves (3–30 kHz) can penetrate seawater to a few tens of metres and a submarine at shallow depth can use them to communicate. A deeper vessel can use a buoy equipped with an antenna on a long cable

A different frequency…
Scientists Find Sounds That Deter Killer Whales from Fish Nets

This article is not the one I read or need and is conflicting but interesting…

noted that the baleen whales in the flight group actually produce lower-frequency songs to prevent orcas from homing in on them.

Look up ‘Azipod’. They don’t have rudders, just drive pods. The pod would be something close to the size of a fully grown orca, but with a 3+ megawatt electric motor in it. Times 4. All mounted on a 1000ft ship moving at 15kn. No way, Jose.
