I've used the search feature and got some insight into parts of the processes.

You can force it towards shore so it gets beached or force it towards currents so the current takes it to shore.

For actual killing out at sea, harpoons and poison.

I also read they could just cut it into smaller pieces out in the sea.

Okay, I get that.

But how exactly would they tow a whole whale back to shore, say with only two people? I mean even with 5-10 people or even 50, that's surely no match for a multi-ton whale? Did they have some sort of super strength?

Weren't some of the distances travelled very large?

I just don't see it. I mean, I know they did it, but how?

Also, do dead whales float? Do they sink after a while? Is there a window of opportunity? Did they have to worry about the whale sinking along the way?

Also, how big were some of the biggest whales hunted?
