Suggestions for new ship weapons?

You know, using cannons is fine you have lightning, fire, grape,etc.
Also having to sail around to attack from behind for broadsides requires a bit of skill as well.
But what if we had mines?? Just think on privateering, if some dude was following you when your about to make repair, you launch a mine and kabloom!!, half or quarter of their hull is damaged.

That would make privateering more interesting when out for some bounty.

Maybe a Torpedo option?? Thoughts and suggestions please....
