I can't imagine anyone swimming with a great axe in the first place.
Not to mention getting enough purchase and leverage WHILE SWIMMING to actually use it effectively. (Not to mention the fact that the ship would be moving during this attempt, as others have mentioned.)
Although I'm not an expert in marine biology, but I've read that sharks often follow ships in hope of an easy meal. I'd think that once the chum hit the water there would be sharks there pretty darn quick to investigate.
