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.

Hi Vance
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?
All the best
GlenSA

David,
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).

Hi Antoine,
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
regards
Antoine

submarine dive
Hello all,
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...
cheers
Antoine
