It sounds a bit BSish to me if a ship can just run over a whale why have they used harpoons for all this time?
I think that the whale would have the awareness that something else large was near to it.
It must not be so easy or again why bother with a harpoon?
That and in my experience many people are full of it and will embellish.For example my neighbor was in Vietnam and I know he
was a true combatant but the story he tells about shooting an M79 into an old french bunker on the beach while he was drunk on R&R I know that it is not true.
I know this because his older brother was also in Nam in a different unit and he says his brother never got a single starch in the war.
Not saying that Gargamel is but his in law is most likely full of it.
