The Rio De Janeiro Maru was a 137 meter passenger-cargo liner, built in Japan before WWII. She was a work horse of the pre-war world, carrying emigrants from Japan, to South Africa, Brazil and on to the West Coast of America, before returning home, on many voyages. However, during the war, she became a submarine tender, and then a cargo transport vessel. She arrived in Chuuk six days before Operation Hailstone, full of munitions, and desperately needed supplies. She languished in a slow death, after being hit by several 1,000 pound bombs in the first strikes of the day. It apparently wasn’t until about 3 am the following morning that she finally sank to her current resting ground.
Bottles in crates on the wall, no wait, spin around, it is actually the floor, or is it the ceiling, it’s easy to get confused in the gloom. Large letters sitting proud in the lopsided bow, spelling the old name, in both Kanji and Roman lettering, amid the sediment and fish. Swim through in to the large cavernous storage decks, taking a peak in to the last moments of the ship, frozen in time. The static prop, once propelling the tons of steel and men through the water to destinations unknown, now sitting, coated in pristine and colorful coral and fish.
Maximum depth to the seafloor is 35 meters, but her port side sits in a nice shallow 10-17 meters. The holds took us to about 28 meters, but there is so much to look at on her hull, one can spend ages ascending slowly.
