| Up at 5 am, eggs benedict for breakfast at 6:30 am, and then went shopping for t-shirts and other stuff the Blue Lagoon Dive Shop. Then back to the room to change and head down to the Blue Lagoon Dive Shop to check my stage cylinder mix. Boat Captain: Ansauo Renis Dive Guide: Tryvin Aisek Monday morning, 9 May 2011 - Shinkoku Maru. With everyone aboard we headed out at 9 a.m. towards the site of the Shinkoku Maru, one of the two mandatory dives in Chuuk. She was one of the eight fleet tankers which refuelled the Japanese Strike Force for Pearl Harbour. Tonnage: 10,020. Length: 152.4 metres. Beam: 19.8 metres. Launched: 13 December 1939. She now features magnificent coral growth and fish life after being hit by a torpedo and sinking to rest on an even keel. The boat crew were worried because of the rain and reduced visibility was making it difficult for them to navigate. We discussed switching to other dive sites, but decided to just proceed slowly and hope conditions would improve. They did eventually and we powered over to the dive site. I was using an eleven litre aluminium stage cylinder with 150 bar of EAN57. In the midship area we explored the bridge, mess, galley, a bathroom and head, plus the sick bay with its operating table. On this dive we penetrated deep into the engine room. At first entering the engine room was like entering a large open space in a large building. From the catwalk the view was like being in a theatre. The huge cylinder heads are held in place with fist sized nuts. Low on the port side of the engine room the torpedo hit shows as a big jagged hole. We saw lots of very spectacular marine life as we made our way around this ship. I switched to the EAN57 stage gas and deep my deep, deco and safety stops. This was a decompression dive of 65 minutes with a maximum depth of 39 metres. What a simply wonderfully varied, relaxing and spectacular dive. Our dive guide, Tryvin, dropped his torch while getting aboard the boat. Ansauo, our dive boat captain, geared up, dived down and retrieved the torch. Impressive. |
