As for the fine nautical tradition of warning others of the "Kraken" (pun intended) of the deep don't we at least get a full glass of RUM while we listen to the same frightfull story for the 5th time? LOL

As I have said in the past I have made a living combining the experiance of those who came before me with their and my vision for solutions to problems others ran away from in abject fear.

I have met few men of wisdom who could not be part of the solution if their politics and or religion allowed it. You have to wonder if a man who can only see or talk about the negatives of a problem has clear enough vision or intent to even participate in the solution. My experiance is that Most can not.

My teams and even our "elderly mentors of experiance" are carfully selected for their exceptional if not fanatical focus on delivering FFF - Form Fits Function. If it won't do the job select a different technology and move on.

But since none of us know what the "requirements" of Will customer are our naysaying and even our solutions are heresay at best. LOL

For all we know the customer wants a big slimy aquaculture hull that has a max speed of 3 knots. Put a wind gnerator on the snorkle and you have a high tech hybrid electric 'Green" sailboat which if done well is not an eyesore of halyards in the marina.

I have a friend that has a lawn for a roof! Can you imagine the look on the contractors face when we explained that! He said we would never keep it from leeking. 20 years later it has never even sweated moisture and he has never spent a dime on air conditioning!

There are plenty of honest concerns to be addressed by men of honest intentions whenever progress is to be made. The contractor made several very good suggestions which I credit with that 20 year record. But a lesser man than my friend, a member of one of my teams, would have folded his hand.

Perhaps, like my friend, Wills investor is looking to make a difference and stand out from the crowd. We can only guess!

I will have to remember this as the absolute minimum requirement-
Goslings of course....

Great post- thanks!

Bntii,

Your posts are a welcome part of the process!
Besides you have good tast in RUM!


If I keep ranting about the process
"I" will owe everyone a round! LOL

That could cost more than the raw hull!

[PanAmMan]

I am inclined to start a thread outside concrete submarine since the goal is to evaluate Steel vs Cement vs ??? With the goal of identifing a technology for a large hull that has much better cost per volume than what I see available today.

Maybee we should call the discussion by it's goal. "Sub Cruiser Hull"

I feel the discussion should include costs associated with 100% sonic or radiologic inspection of seams and or the skin as well as ongoing maintenance concerns like corrosion / ablasion / depth cycling / vibration / marine growth control and or maintenance.

I am open to sugestions on where this discussion should take place.

Mydauphin,

My regular sailboat "if you could call it that" uses composting toilets. You have to remove a "Bucket Size" tray once a month and the material is dry. with a carbon air filter they are even certified for use in mines!

The larger problem is of course your sink and shower "grey water". That discussion would make a neat cross post to Simple Sub Systems.

Maybe some are alluding to my response to watson as whether I have ocean experience. That went into the other experience in the Albacore boat. That led to my overall experience in ife, which I can justify if I want to sell hulls, as opposed to buying one.
That said, the discussion of hull material is a major concern given the advancements to composite materials available. If I can learn and find out what is available, that can change my mind. I haven't heard much about using the concrete as a medium with additives, other than it can make the concrete model currently proposed weaker and away from the proven method of mixtures. It seems that it is a matter of scientific testing, just as a starting point.
The issue of hull material is still on the floor, and if other, less cost prohibitive materials are out there, I would like to hear about them

But I am for free expression in creation, and if you think your vessel is safe and performant, why not, let the concrete flow, and the sub dive, but do not make assertions you can back up, that will be delusional.
You are in Columbia I beleive, wounderful country, nice people, you must be happy overthere.
Cheers

dear daniel if you have a problem with floating concrete please update your knowledge at:
http://imulead.com/tolimared/concret...ne/anuncios/du

For the more basic understanding please check laws of flotation Archimedes.
http://en.wikipedia.org/wiki/Archimedes

Flotation has nothing to do with the material - just weight and displacement - in a nutshell.

If you think i have no idea what i am doing. I can only say that i have done it before - so what have you done/achived to be endorsed to that kind of opinion?

Cheers,
Wil

Look at the yellow page and you find myriad of people working concrete. The whole submarine calculations is complexe and extremely diversified . Do you have any clue what is a submarine? You try to hide behind false problem, the concrete.
What I have done? design in submarine while you were in highschool, and yes I am a naval architect, but this is not relevant. Everybody can study everything. Your question is inapropriate and typical of a salesman who show by diversion again his unability to realy go to the heart of the project. This is a so called by you a SUBMARINE, prove it. No concrete crap any more please, it start to be stupid. And please your link are pathetique. Grow up.
By the way your 20 ton is not a submarine, walk up, and don't try to fool people. You never did a submarine, you put in the water a concrete balloon. and you will never built a submarine because you don't know how,and mostly you want to sell. Bad, bad.

Nice country you are working in, nice people. (The Columbian)
Cheers
Daniel

hmm that kind of comment explains itself - naval architect - 40 years in military submarine galley piping design...unable to sell any of his own ideas - lot of bitterness...unable to look outside his box... etc...

Whatever - i have no problem with YOU designing what ever YOU design - (i see from your profile it is traditional sailing boats...) i have also no problem if you think a concrete submarine yacht as proposed by concretesubmarine.com is no SUBMARINE at all (for the military sub builder).

Call it a submersible houseboat, a self propelled concrete habitat, a concrete living bubble of apartment size under the sea, a seastaeding solution, - what ever - i am fine with that.


Yust relax and bring up a point that is worth of discussion...

Hello PanAmMan,

That is a very interesting point.

A military submarine has a building cost of some over USD 200,000 per cubic meter / at "European Submarine Structures AB" (our newly founded company - motherhouse in Sweden - subsidiary and building site in Colombia) we are going for a cost of 331 Euro per cubic meter.

This is in the range of the average US and European housing market prices. The basic idea is to get "hurricane safe marine living space" in a price range that makes it available for normal peoples budgets...

The 200 ton hull (picture above) is the room and floor equivalent of a 68 square meter apartment - for me the most difficult part of the design and engineering is in the fact that this apartment operates "off grid" so other than in your city apartment you have to take care of your supplies, waste, and energy. - this is a similar problem as it appears in a surface yacht and it can be solved by standard yacht solutions.

In a submarine other than in a surface yacht weight is no problem. In a 200 ton hull you have about 100 tons available for the "off grid" solutions - mayor tank capacity, - mayor store capacity, - so in general mayor range and independence.

Combined with weather safety, burglar and pirate safety, those are strong arguments for a submarine cruiser...

Did I read this right in that you want to market a submarine yacht?

I'm sure others have asked this:
Where/how do I store and/or use my:
-BBQ?
-PWCs?
-kayaks?
-dinghy?
-fishing gear to catch dinner enroute?
-and HTF do I get into my inflatable rescue raft?

How does my harem suntan while enroute?

Best way to avoid hurricanes? Weather alerts.
Best way for 50% of the pop. who experience some level of claustrophobia and wish to avoid it-stay out of subs.

I happen to love the wind and sun in my hair and on my face.
I love the waves dancing in the light,watching the clouds,and spotting wildlife......as do 100% of the boaters out there.

There's 33,000 unsold power and 28,000 unsold sail boats on yachtworld,and the average boat stays on the market for several years.

Good luck

So - the sub is out of its shed - must be 9 months over the original delivery date.

So how is the status of the -
engine installation
wiring and dive controls
life support systems
Marine safety gear (waiting on the anchor deployment system to be displayed)
Marine Insurance
Coastguard clearance

Is the couch available for the average mortal, or is that as the rest of the vessel still under development? For the next century I guess it will remain "under development".
Did one of you notice that a complete ***** has choosen the placement of the windows? They look upwards. Maybe I´m wrong and they where designed that way on purpose!? `cos the only interesting action one will see when operating this tomb is the action of the rescue team trying to salvage the dumbass crew!?

I guess the big air lock shown in the nice computer game picture is for transferring the "hell of a lot of money" to the rescue team, without getting the couch wet!
