I really wish they had published the brand of fishing line he used, because mine always breaks when I try to pull up anything heavier than a submerged tire or shopping cart.
PS - there is a submerged submarine, whereabouts unknown, in Illinois: https://en.wikipedia.org/wiki/SM_UC-97
Lots of submarines, all over the world, were made during those years.
