M451 was the 2nd dive for the camp. I agreed to do that also with CCR guys Riku and Kalle. I swapped my tanks to twin-12 liter tanks of 28% Nitrox, and planned to take just the 50% deco tank as this was a shallower dive to max 30 m. We agreed to 90 min dive time with some deco.
We agreed with Anne that she will leave her strobe on the line, and Riku will bring it back as we were likely the last ones to ascend.
Again there was no marker buoy so Orbiit dropped a shot. Weather was still somewhat rough and hight waves. A few pairs went down before us, and when we got to the bottom, we could see that the shot was not at the wreck but someone had drawn a reel line out already. We followed the line which first went to a huge rock, then turned 90 degrees and soon there was the broken front part of the wreck. Kalle was not happy about the reel line, so he attached his own reel to the wreck, and we swam back to the shot to attach to ascent the line and then back to wreck. That only took a few minutes. Then we started diving around the wreck. First we headed to the rear part, where there is the bridge tower, the rear facing big gun, and then finally to look at the big twin propellers. On the way we noticed that the anchor chain of Orbiit was going across the rear deck, which was really bad thing. The anchor chain was beating the bottom and raising silt that made visibility poor. We continued diving to the bow, but there the visibility is always bad. After 70 min decided to start ascent. I had 75 bar left. So Kalle took his reel, and we followed him back to the shot, Riku took the strobe and we started ascending. I switched to 50% deco tank at 21 m, which was really soon as we only had to ascent a few meters to get there. We did 15 min deco and then back to surface.
I had been at this wreck in June, but then the visibility was really poor and we did not go to the bow at all. Now I had a chance to see the bow section. It is quite messy as the boat has broken pretty badly, the boat has split into two parts and the front deck is tilted 45 degrees, the right side is buried into mud.
At the surface there was already planning ongoing how to get the Orbiit’s anchor up without further damaging the wreck. It was decided that we will do a 2nd dive here to help planning the anchor chain recovery.
