Hi Trymix, South Africa is well known as a home of extreme strokery and I think that the pictures on: http://www.wrectdivers.co.za/ (see "The Story so Far") are an excellent example of this. The guys are/were planning to use a block + full face mask. For one good reason of why not to do this, see the recent posts on Tony Maffatone's death. I dont have any first hand experience of the Oceanos, but from what I hear, the currents can be extremely strong and deep scooters are a necessity. My information may be a little out of date, but I understand that this expedition has been cancelled i.e. the group did not dive the Oceanos. Why dont you post your real name ? You will find people are a lot more willing to talk if they know who you are!

I found one item under the technical info very interesting: "Once the primary divers have reached the surface, they will be transferred to the medical boat where they will be placed on a drip and pure oxygen. The drip is to counter any dehydration experienced and the oxygen is used against decompression sickness." This isn't the first time I've heard of this technique, but I thought that it had been written off. I think that the idea was to discourage bubble formation by increasing the blood pressure, and because the saline acted as an anti-coagulant. Didn't Rehan Bouwer try this technique in about 1990, and decide it was not worth the effort? The idea seems ill-founded to me. The Oceanos lies in an area known for strong currents, with the result that seperation is a realistic situation. If this is the case, then easy return to the medical boat cannot be assured. I would also not like to be the medic who has to insert a drip into a cold diver on a small pitching boat. And surely if the surface O2 and the intravenous drip are needed, then the deco has been cut dangerously short? Does anyone else practise this technique?
