Last dive of this trip. We where back in Hurghada Harbour and actually ended our trip with a twin wreck dive. The wreck of El Mina, and a fishing boat. both lies at approx 30 metres and approx 70 meters apart. The El Mina is an old Mine layer that was bombed by Israel in 197 . It was a great dive to end this trip with. In retrospect, looking back at our week with Blue o Two onboard the M/Y Blue Melody, I would say that this is an fantastic way of diving. 16,5 hours of diving on 6 days, great service and good food. My working collegues said when I came back to work; Had a good and relaxing trip, all rested out now? – No, I have been diving, I think I need another week to get all rested out ;)

Dive #128

Location: Sha’ab El Erg, Red Sea, Egypt
Time down: 07:34 | Time up: 08:48 | Divetime: 74 min | Max depth: 13.0 meter | Average depth: 9.6 meter
Water temp: 23° | O² used: 60 litre | Dil used: 45 litre | Total RB divetime: 59h 30min

Day 6 of our trip and we had spent the night at anchor. So first dive of this last dive day was made at the same location, just to clear the help clear the No-fly time on our computers. I was a bit amazed by the O2 consumption, when checking the logs. 60 litres of O2 on a 74 min dive. That is 0.8 lpm! And also, since we didn’t move that much up and down during the dive, 45 litres of diluent was used up. So, 105 litres of gas used on a 74 minute dive to 14 metres. This is Recreational Rebreather Diving in its essence. An OC diver with a fairly good SAC would have used 2800 litres of gas on this dive. That is a full 15 litres/200 bar tank. I used 35 bar in my 3 litres tanks.
