| Boat Captain: Ansauo Renis Dive Guide: Tryvin Aisek Wednesday afternoon, 11 May 2011 - Yamagiri Maru. With our peaceful break on the island completed, we headed over to the wreck site of the Yamagiri Maru, a large 6 hold freighter. Tonnage: 6,439. Length: 133 metres. Beam: 17.8 metres. Launched: 30 May 1939. She is now resting on her port side in 34 metres. I had 100 bar of air remaining in the twin 11 litre cylinders and 150 bar of EAN57 remaining in the stage. Plenty for this dive, though I'd have to monitor my air consumption carefully. We headed down onto the wreck and deep into the engine room with its 2 rows of 3 cylinders. Tryvin showed us a skull stuck in between some machinery. We then made our way out and into hold 5 with its cargo of giant, amour piercing, artillery shells destined for the 46 cm (18 inch) guns of the battleships Yamato and Musashi. The nine 46 cm guns of these ships were the largest artillery ever put on board of any ship and had a maximum reach of 42 km. The shells are about one metre long and weigh about 1460 kg a piece. There is also a steamroller in this hold. As we headed back towards the bow, Laurent spotted a large shark and signalled me, but I couldn't see it. I switched to the EAN57 stage gas and did my deep and safety stops while admiring the coral growth on the side of the hull. This was a non-decompression dive of 36 minutes with a maximum depth of 26 metres. FINISHING UP AT CHUUK LAGOON Five days of magnificent diving was at an end. The three of us discussed the different things we each remembered most as we headed back to the Blue Lagoon Dive Shop. It was time to clean and dismantle our dive gear and take it back to our rooms for drying. By 1 p.m. I had everything laid out to dry on the balcony of my room and headed off for lunch at the Blue Lagoon Dive Resort. For lunch at the Blue Lagoon Dive Resort I ordered the grilled tuna with rice and tartaire sauce again. Then followed it with a banana split. After lunch I went back to the Blue Lagoon Dive Shop to settle up my bill: US$410 extra for the twins, stages and nitrox fills; plus US$250 for my merchandise purchases. Some of the others had organised to go out on a fishing trip for the afternoon. I chose to rest at the resort. The fishing trip proved to be very exciting, but no fish were caught. Dinner was a complimentary BBQ organised for our group by the Blue Lagoon Dive Shop. All three boat and dive crews joined us for this, plus cooked the BBQ feast. It was the best meal of our stay. I went up to the restaurant and ordered banana splits for Ansauo and myself. Turned out he was a bit too under the weather by the time I got back to properly enjoy his. |
