The USS Oriskany and the boat on the deck

[Contrast]

I watched the sinking of the USS Oriskany and there is a boat on the deck that floated when the Oriskany sunk below the surface. What was the purpose of this boat on the deck?

That boat housed the computer controls that sequenced the explosives that were below decks. This way they didn't loose them.
