I guess I'll have to go back and watch the how-we-dun-it show.

Side view of Alicia AP6.  The double bubble doesn't give me a warm, fuzzy feeling primarily because I don't intuitively understand it.  it would be interesting to see how the stresses move as pressure increases.  -JT

I read some stuff about that double bubble deal. It was a monumental pain for the manufacturer and there were several failures before they finally got one to work. Connecting the two adds some serious stress, apparently. HBOI looked into a Sub 3 concept (a double bubble) but never seriously considered interconnecting the pressure hulls. The design called for two crewed hulls with a containment pod between them which would hold all the structure: MBTs, gases, and batteries, et al, in a streamlined shell. There was a time when it could have been built for not much money as HBOI already had all the data and certs for acrylic and the operating systems, and nobody in the world pushed plastic harder than they did. In other words, not a new design, but a reconfiguration of the old one. In any case, it didn't happen, and now it's all a bunch of expensive museum pieces. Sigh.

Hi Hank,

I think they made some passing reference in the video to the cost over-run, don't know if they recited the $2 million figure or not.  That would equate to about $2.47 million today.

Other stats:  18 tonnes, 37 feet long, tested to 1350 ft., 6 persons.  Marlin Subs was planning improved subs  (P7) in the series, but I don't know what came of it since they have developed several other types.

That is not a surprise,  Was that in the video, I skipped over some of it.
I am adding a couple of these guys to my hero list.

Cost over run took it to $2 million 10 years ago.

I don't think the overdramatized that truck load of money it took. Wonder when it was in the water last. Maybe they'd let us keep it at Jon's house in the Keys. We could hold our seminars underwater.

Great Nova video on the building of the Alicia including problems encountered.  I learned a thing or two.  Yeah, they dramatize a bit to make it more interesting to the general public.
