Diving Bells

Diving bells (and the principles used by them) have been utilized throughout the history of naval warfare. By simply trapping air, it allows people to dive deeper.

In SoT, we're basically wreck salvagers. To me, it doesn't make sense that our ships wouldn't at least have some kind of bladder that we could fill with air to dive.

My suggestion is either: full on diving bell, with pulleys to raise and lower, or an item on the ship that operates as a kind of reverse bucket. Swipe at the air with some canvas sack, and upon first use it deflates. If you drop it you can pick another up at the merchant guild. One per ship.

Any thoughts? I wish these threads would get a mark on them to see if Rare at least glanced at it xD
