[PSUBS-MAILIST] Personal_Submersibles Digest, Vol 51, Issue 30

Greg,
I've been following OceanGate for a while. I've also been sending them
applications for open engineering and technician positions for almost a
year now. They own several subs:
Suds- a K350 with steel MBT's
Antipodes - Ex PC1501 with a 2nd dome mounted to the stern (an idea I
really like)
Cyclops 1 - The "Prototype" for Cyclops 2. Don't know the entire story
about that one.
Cyclops 2 - A deep diver under construction with a carbon fiber composite
hull (!!!) and titanium heads

A polymer composite hull sounds pretty dubious to me. I just don't see the
benefit. There has never been, and never will be, such a thing as a
"lightweight" submarine. And from what little materials characterization
work I've done, I know that he could have built a fleet of steel subs for
the price of one plastic one.
