The Tottori Maru was ultimately sunk by the USS Hammerhead while attempting a supply mission. But as I swim around the wreckage, her more infamous history attacks my senses, sending shivers through me. I recount in my mind’s eye the horrific events witnessed by the twisted eroding metal. My torchlight briefly touches a ladder reaching deep into the dark holds and encouraging further my imagination. Finally, my buddy flashing a signal brings me back, the dive time turns us. We head for the assent line. A vast unexplored shipwreck deserves days, not minutes of bottom time. Yet, so much is left unexplored.
