-----Original Message-----If I was going to build one of these ( and I did design on like it when I was about 14) I'd go ambient, which may explain the 30 ft limit he puts on it, no decompression times!

Hi Brent,Just did some homework on "Chinese death trap".The article says its 1.6 tonnes & calculating out the displacement of 7 drums thats about right.Wich means the drums must be his pressure hull & not an outer ballast tank.He says he can go to 30ft, but a thick 1.2mm drum has a crush depth of 16ft. If he reinforced allthe drums half way that would only give him 33ft. Might be wrong, he might be an ardent follower of psubs.org.& have built it to ABS standards.Alan.Sent: Monday, September 07, 2009 7:21 AMSubject: Re: [PSUBS-MAILIST] Chinese home-built sub makes the waterLooks to me, like Xiangli has about the same hatch land height as my original K boat.

Looks like he is working on his TV periscope, the mast seems to be made of a piece of clear acrylic pipe. Note the red line on the front of the sail, I am guessing that this is his trim line. As I stated earlier, he is operating with very little freeboard.
