I still don't exactly understand why these subs aren't just tethered to the ship.

Sure have a battery system as back-up for loss of shore-power (so that you can surface). But if the ROVs [1] they used to find the wreckage can be tethered to a ship why can't the dive sub? It would just be a glorified elevator at this point which sounds much simpler.

Don’t have a source handy but have read the tethering is possible but required more specialized and expensive ships. When the tethers /are/ used I found it interesting the whole reel is welded onto the ship’s deck

They could! Presumably skipping the tether saved him time or money. Fun stuff
