Who was Cassin Young, you say? He was commander of the USS Vestal (AR 4), a repair ship that was moored inboard of the "Arizona" on Dec 7, 1941. He was blown off the deck by bombs but swam back to his ship, and in spite of taking on water from bomb damage, he moved the "Vestal" to shallow water and beached her to prevent her sinking. He was awarded the CMH for this action. He was then given command of the cruiser USS San Francisco (CA 38) but was killed at Guadalcanal.
You can only tour the decks but it's an interesting place to visit.
