[PSUBS-MAILIST] exotic steel

[Alan via Personal_Submersibles]

Scott,
yes the view ports could be an expensive part.
Paul Morehouse mentioned a German firm that was pressing large acrylic hemispheres.
That process could bring the view port price down a bit.
Here's Graham Hawke's catamaran in case you haven't seen it.

After spending a lot of time down there with Karl it got me thinking a lot. It would be a low fuel expense, easy launching capability because of the wide base, yet still fast for a sailing vessel. Once I had everything built and done I would either hire a CEO to run my company and I would partially retire and run scientific expeditions or I would just sell my company. The problem with a 2000 meter submarine is the veiwports start to get small and the weight goes way up. I would definitely build to all classification standards, but I would not pay to have the classifications done.
