Hello Hugh, Ya I saw the concept drawing and then looked at the 1.2m pressure hull diameter, and said no way are they installing two seats, side by side for adults. I'm really liking that self centering distress buoy. Can you take some pictures of it and the internal workings under the fairing. Drawings would be wonderful as well, but Christmas is to far away to use it for leverage. It is fun working thru a existing sub and discovering all manor of things. I'm still finding things on my K-250. I've used some online free translator web sites for translating some German text I needed in English, and they worked well. For Swedish to English try the below links. http://www.google.com/search?q=swedish+to+english&sourceid=ie7&rls=com.microsoft:en-US&ie=utf8&oe=utf8 Also you can try to contact the Swedish builder of the Malen sub, Anders. He can translate for you if you make it interesting. He might also benefit from the data. Anders Ljung andersljung.engineering@gmail.com Did you ever find a good source for the pair of domes you were looking for? Emile makes nice blown domes. Cliff had a more standard hydraulic pump on the R300 that was quite noisy and used a lot of power. So he changed it out to a much quieter unit. You might want to ask him about it. His was not for the propulsion. The Voyager tourist submarines built by Work Boats Northwest in Seattle, that used to operate in Hawaii used a large stern prop that was hydraulically powered. They were the fastest tourist subs at that time. But not because of them being hydraulically driven however. They used peanut oil to make internal spills safer on the reef. I don't know how often they had to change it out. I know two of the main guys that built two of the Voyager subs if you have any questions. One lives close to me now, and works for the Aqua Jet company I use. " Be yourself. Everyone else is already taken.

Wont do 13 knots and does not have 2700hp!! It is all driven hydraulically. All the rest of the stuff is right. No, I haven’t dived it yet. I am going through it with a fine tooth and going to refurbish all the Hydraulic motors etc. The O2 & CO2 monitors are broken, and the whole thing needs a bit of a tidy up and some TLC. Checked out all the batteries (28 ) and they are all OK. However, it is a good craft with pump on the hard buoyancy. I have found one of the hydraulic motors with water in it and some rust! Hydraulics a bit noisy too! Electric motors are much quieter. I believe it is the only one that was built and it never got final certification from Lloyds although I have drawings and calcs all stamped by Lloyds and certs for materials, inspection etc. However it was all done in Sweden and most of the stuff is in Swedish. I think I should get a Swedish girl for translation!! The weight of it is a problem as it means cranes and trucks for transport and then towing out for diving. The artists view shows 3 seats but no way. That was the concept if it were going to be built with a big Dome up the bow but it has four flat viewports there instead. Bigger than a K350 but not that much. Having a lot of fun going over it and working things out. Needs the drop weight re-modelling and some missing panels made and put back on. At 200 meters capability it should handle most places around New Zealand. It was built in 1986. I am trying to get it certified and if not to Lloyds then at least to NZ Maritime. Keeps me busy, and hope to have it all ready by September. Chs Hugh
