I've seen this happen before up in Juneau, AK. Cruise ship pulled into port on a nice busy day, with a whale skewered on the bulbous bow. I think it happens a few times every year up in alaska, and in the N.E.
There was a friend of mine who worked on a whale watching boat out of somewhere in Mass. To make a long story short, as they were coming back in from a whale watch, they ran over a whale. Whale gut's everywhere. To make it worse, they ruined both props, so were dead in the water, with pieces of whale carcass around the boat. 😱
I know some other people who hit a whale in their sail boat in the gulf of Maine, they didnt see it, as it was night time, and dont know if they killed it or not.
The problem is that whales are too slow. They can hear the ships coming, but can't get out of the way.
