| For lunch at the Blue Lagoon Dive Resort I ordered the grilled tuna with rice. I expected that like everything else it would be overcooked so asked if I could have some tartar sauce as well. My expectations were met and the tartar sauce helped to componsate. The rice turned out to be the winner of the choices of rice, chips or a baked potato. Went back to my room and took a nap, but overslept. Peter Fear came knocking on the door just as I was getting back into my Thermalskin. Boat Captain: Ansauo Renis Dive Guide: Tryvin Aisek Sunday afternoon, 8 May 2011 - Rio De Janeiro Maru. Back at the Blue Lagoon Dive Shop after lunch, the other divers were already waiting on the dive boat, plus our three snorkelers were back with us. I had to check my stage gas. Turned out they'd filled the 5 litre cylinder used by Peter Fear on the previous dive, rather than the 11 litre one used by me. So Peter Fear and I switched cylinders. As we geared up on the Rio De Janeiro Maru dive site, a dive boat from the Thorfin live aboard arrived. The Rio De Janeiro Maru is a large passenger liner converted to a submarine tender and depot ship. Tonnage: 9,627. Length: 140.5 metres. Beam: 18.9 metres. The ship is lying on its starboard beam. We headed along the port side which is now the top, back to the stern of the ship. Twin shafts emerge from the contoured bottom of the ship, with the keel separating them. Both propellers remain on the ship. We headed towards the bow along what was the top of the ship and into a cargo hold. There we saw large 15 cm calibre gun barrels and shells. We journeyed deep into the engine room. I followed our dive guide with the others behind me. There were a few times I thought there was no way I was going to make it through in some places, but managed to do so. It turned out the others were all thinking the same thing. Eventually we made it to the bow and onto the port side. As we came up to 14 metres I switched to the EAN61 stage gas. We did our deco and deep stops heading along the port side back toward the stern. I signalled to Laurent and asked him to watch me shoot my DSMB and then did so. Turns out it wasn't in a situation that would enable him to sign it off as a part of my BSAC Sports Diver certification. Bugger! This was a decompression dive of 61 minutes with a maximum depth of 29 metres. Eventually we were all back aboard the dive boat and we headed over to the wreck of a Jananese Zero airplane. |
