RE: [PSUBS-MAILIST] submersible design

["Alec Smyth" <Alec.Smyth@compuware.com>]

I've seen one PSUB that meets that description, Greg Cottrell's. It
seats 3 people in comfort, and it didn't cost a bunch because he built
it from a WWII vintage fuel storage tank. Unfortunately he's not online,
but if you're ever in the mid Atlantic region you might want to hook up
and go take a look at it. The pressure hull is your basic cylinder, but
larger in diameter than a K boat and proportionally shorter. There's a
flat window on the front, again like the Ks. The seating arrangement as
I recall was U shaped, with the bow at the open end of the U. You could
make it a bit fancier and increase your depth rating by substituting a
spherical window for the flat one, but as always that comes at a price.

Rgds,

Subject: [PSUBS-MAILIST] submersible design

Hi Guys,

Ok, so the K-250 and K-350 designs are quite popular. After looking at
many interior and exterior photos of these beasts, I've concluded that
people don't build/buy these subs for their comfort, nor for taking
down alot of passengers.

Is there any middle ground with current submersible designs? It seems
to be you can either build/buy a K-350, and either descend into the
briney deep (read it out loud with a pirate accent for the desired
effect) alone, or with a rather squashed companion; buy a Sport Sub
and get wet (just like scuba), stay above 40 metres (just like scuba),
and stay within the depth  times of the RDP (just like scuba); or, you
can spend a few million on a larger tourist vessel.

Is there any middle ground for submersible design? Something that can
take perhaps 3 or 4 people, still be at one-atmosphere pressure, and
not cost more than an average home?

Are there any other one-atmosphere submersible plans available,
either? Most prospective sub builders seem to have the predicament of
either buying the K-250/K-350 plans (which are safe, well tested and
documented I might add), or try their hand at designing their own
untested craft.
