Hi Vance,
I put a childs swing seat in a friends
K-250 about 20 years ago. We took the variable out so one of us could lie down
and the other sat in the swing. Worked but it was TIGHT!
Btw, did you work with Don Liberatore over
at HBOI?

No, on the seats. One of the guys used a
flexible child's swing seat on chains, easy to drop out of the way, and I may
use that. The sub is so small that those kinds of savings are important.
I am building MBTs along the style of
Carsten and Emile's KSS, rather than the straight shoulder tanks. They give the
best of both worlds--improving visibility over the bow without totally ruining
the side vision from the conning tower. Plus they five stability in all
directions while on the surface as they wrap more or less completely around the
hull.
I'll hold off on the manipulator
penetration until our ball and socket assembly is built and tested (like the
Nektons). If that works, then I'll have to add a ring support into the fwd head
next to the main viewport, or possibly in the side like the Nektons, where I
already have extra port and starboard viewports.
Lift bags are easy. Just run a hose
inside the bag and roll it up in a big PVC tube for storage. The hook end will
run out front somewhere you can pick it up with the manip. Hook it up, back
away to deploy the bag (but not to far) and then inflate. The fill tube should
be set up so that it pulls out as the bag lifts away. Done deal. We used that kind
of rig over and over again with the Johnson SeaLinks to recover science
packages and it worked first time, every time.

How far are you with the saddle mbt
design?I am busy welding 8 SS hydraulic socket fittings to the Hull I am
planning on fitting a small manipulator later ,I am also fitting extra elec
thru hull and 2 extra air nipples 1 for a emergency lift bag which could
also be used to lift heavy items off the bottom ,the other for a hose
which could be attached to the manipulator to blow lift bags.Any suggestions
welcome.
By the way is your seats made to
K350 spec?

You're absolutely right. I even got
people to pay ME for that. But I went for the same reasons you suspect.

I like to think of what the people get for the ticket they purchase. To leave
the world they know to a world of unknowns. To explore and excite. To
imagine what more could exist. To do more than just exist...to live.
I would wager that if offered the money back in return
for the thrill of this short submarine ride...
you'd have few complaints.
I for one would love to go.

Oh yeah, number of dives. If the maximum
capacity thing works, then you're talking 2800 dives or so. In reality, it will
probably be more, maybe twice as many. 2800 dives, 40 passengers per, that's
about 110,000 paying passengers. I'd sure like to have the hot dog concession
for that!!!

Let's extrapolate: 40 passengers per
trip, 6 dives per day, $65 US per seat. What, $15K/day on a good day? If the
sub cost $3.5M US, figure twice that overall for startup, equipment and seed
money for the first two years--$7M, give or take. That's divides out to 67
weeks operating 7 days per at maximum or near maximum capacity to square up the
investment. Double the time, even if it's a good site, and triple it
if the traffic is slower. Call it four years to make your original investment
back. Probably longer. However, ameliorated over a reasonable period, say a
decade, I'm betting the return is good. Good enough for Atlantis to build a
trainload of submarines and a few others to follow suit. Mind you, after ten
years the certifying agency is going to want a tear down and proof testing,
plus viewport replacements and the like, so you get your check book out and
start all over again. My guess is that whoever owns these things is playing
way, way, way over my head (sic).

It's a huge sub with heaps of room
inside.
This link shows it's vital statistics
& inside view.
must have cost a fortune; they'd need to
do a lot of dives
to justify the investment.

I think it is its
sister sub on the Lanzarote island, operated by the same company.
My 'dive
certificate' showed those two subs have logged 20,000 dives together... (since
1997 I think).
that is quite a lot,
sending some 800,000 people underwater

I had a nice experience
last week, I took a dive for the first time in a sub, a tourist sub on the
coast of one of the Canary Isles.
For a guy that
has thought about building a submarine for a few years without touching
one,
it is quite
exciting (though not to the point to pee in your pants ;-0 )
the sub itself was a
big (100ton) 18m long cylinder, moved by 6 15kW orientable thrusters,
quite slow, but with very good viewing (two seats for a large 22" window)
the dive lasted for
about 45mn, went down to 45m depth. The feeling of a very slow motion free fall
when the ballasts are purged felt weird (It did not feel like there was a HBT
on the sub).
But the best was to
see my 3yr old son's face glued to the window, as a big sting ray with a diver
playing with it passed by our window...
