The concrete submarine yacht project has released a number of photos on the internet to document what we have been doing in the three decades of our submarine yacht development. Below is a summary of all those pictures at a single web page with short comments. The page you are viewing contains hundreds of photos so please be patient and wait for complete loading of the page.
 
 

Concrete Submarine Yacht 200 ton / 18m – a self propelled habitat unit, for a California customer, finished in raw building, moving toward the waterline. Status 15. October 2009. The hull is the space and volume equivalent of a 68 square meter apartment. The cost per cubic meter living space is comparable to European and US real estate costs (331 Euro / 480 USD per cubic meter). Compared to figures of 52.0000 USD per cubic meter of living space as offered by other submarine providers we performed a quantum leap in affordability.

 

3 D model of the 200 ton / 18m submarine yacht finished in raw building in Cartagena Colombia. The barren hull has a building time of 12 months and a budget of 331 euro per ton. It is the first hull of a series production that will apply the lections learned with the 20 ton prototype in Europe. The living space of 200 cubic meter about twice the living space of Ben Franklin will enable a small crew to be comfortable over long periods of time in open ocean cruising. The idea is to provide a living space that gives the owner “leave coffee cup on the table“ conditions in any sea state. This is something that a surface yacht can not give to you.

 

 

 

200 ton Submarine Yacht 18m / 4,6m the nose of the hull sticking out of the hangar girl in front. Due to the local conditions of the shipyard it was necessary to build the hull in a Hangar about 150m from the waterline. When it was finished we had to do a movement "out of the hangar" where heavy cranes could not access for assistance due to the proximity of the hangar roof, columns and other shipyard installations.

The hull a couple of months later already ballasted and equiped with a sail (tower) that avoids waves going into the hatch when open. In this status the opening of the ballast valve adds some 200l water (200kg) to make the boat dive.

Craning manouver on the lake, this is the only site where a industrial crane can come close enough to the shore and the water is deep enough to put a 20ton hull into the lake. Unfortunatly this space was later converted into a sandy beach for tourism purpose. The hull was trapped in the lake since then as there was no way to lift it out of the water again.
 
 
Me on top of the hull having a look at the inside - not a single drop of water entering - very good !
 
Pushing the hull out of the hangar with hidraulic jacks - this method will become handy on a much larger scale with the 200 ton boat many years later.

A couple of weeks later on the lake - the hull is anchored in front of Camping Grabner in Steinbach - we are putting in the fixed ballast to bring the hull to its submarine yacht floatation line. Still missing the sail (tower) structure, the acrylic hatch is open. 2 Snorkel tubes for ventilation to keep the inside a condensation free and dry space.
 
Inside the hull of a concrete submarine. No ! it is not a claustrophobic dark and humid space. Light is comming in trough the viewports and make the interior nicer than the space in the belly of a average sailing yacht everything is dry and the temperature is similar to the sourrounding water - cool on hot summer days and warm in winter. Yacht owners who spend a fortune in yacht air condition are stunned how fine the inside of a concrete submarine yacht is.
The picture above shows a 4 seat configuration with the engine room divider/door made in wood. The pictures below shows the ballast below floor configuration in bigger yacht submarines. The ballast is stored in cells below the flat floor.
 
The sketch is for a 15m sub that was in plan for a expedition sub. This sub would not be big enough to have a sail that works as a closed cabin but would protect a person standing on the sub with a barrier of 120 cm similar to the sail of the prototype sub.

A yacht sub that will come to a size where it becomes a submerged living space of considerable size similar to a big yacht hosting all the comfort and luxury for a extended family is a project we are still looking forward to realize.
The boat below was a small expedition sub that would stand tough conditions and can left alone during months in bear country. For everyone who ever have seen what a bear can do to a yacht or a car when looking for food will be clear why a submarine is a excellent solution due to its quality to be unopenable for bears, pirates and other burglers.
 
The submarine mega yacht - this boat will still get you all the attention when showing up in Monaco among all those floating millionaire palace yachts. Even if it is a few meters shorter than the stars of the market.
 
What if we keep the concept more stationary - a deep sea salvage habitat to bring a crew with all its supplies down to a salvage site and do some work with ROV jim suit and similar - non saturation devices. This would skip the need of a expensive surface ship that is suceptible to climate.
 
Living space on the ocean and below the waves. Concrete shell structures can offer a wide range of solutions.
 
The sub surface habitat - just out of reach of the waves - still benefits from sunlight. A deckspace to use when weather is fine. Safety below the waves when things become ugly - this can take "houseboats" to the open ocean - seasteading - can be a new style of living.
 
 
Concrete Spheres in a double hull configuration for a autonomous salvage and investigation vessel. Concrete spheres can be built in unlimited size so this boat can be really big. Very different to the small boats based on steel and titanium spheres that can only be built to the limited size of 2m diameter.
 
What Jules Verne predicted was not military submarines - it was a boat that would allow its crew to live and stay under the waves - captain nemo created a new lifestyle - yachting lifestyle is good - submarine yachting is better.

Out of the shed, the concrete submarine yacht on its way to the water. Moving a 100 ton hull is a task that needs a similar amount of effort and manhours than building it. While moving we are testing for hog and sag resitance, torsion, strange forces of all kind...
 
We have pulled a bit out of the discussion, on most of the forums we presented our projects, we are no longer going to discuss questions like "is concrete a feasable building material for private submarines" this kind of questions is already answered - what we want to discuss now is "what is the future of submarine yachting"....
 
Our Submarine Yacht ready to launch on the waterfront we have made the 150m movement from the Hangar in the background to the water. This was also a test for structural soundness of the hull as the hog and sag forces as well as the torsion forces that the hull has to hold in this kind of movemen is clearly much bigger than the strange forces that come up in floating status.
 
 
The real size of the submarine hull becomes obvious when watching the small man in the shadow on the right side of the foto. Moving that monster over land is a tru intimidating task but we made it with 4 man team.
 
 
The hull adopting the final angle that will be constant while moving forward to touch the water. Once the nose is supported by buoyancy the hull will settle to float on the middle line.
 
 
It is of essence to hold the hull in a position where the "rolling movement" is controlled the launch crew is correcting any angle inmediatly.
 
 
The hull is moved on a carefully chosen mix of wood, grease, and earth, we have a good control over the actual friction forces in play by checking on the push forces necessary to achive a movement.
 
 

Unfortunatly we have to stop the movement at this point and send the launch team home. A new harbor captain is in charge and he is not comfortable with "launching a submarine in his jurisdiction" especially since the bad guys in the jungles have finally gone submarine too... It is our project philosophy to keep everybody comfortable so we need to take out the pressure and give some time to become familiar with the project. We already hold a valid permit to deliver the hull to california as deck load. The project was desigend for a transfer of the hull autopropelled and not as deckfreight.

The point is, that the hull is ready in raw building, and we made it in budget. So we have basicly already proved what needed to be proved. We can not only make those hulls work (this was already proved by the prototype built in the nightees) - we have also proved now that we can build hulls in a much larger scale and still keep the project in a budget frame of 331 Euro per ton of displacement although third party factors may interfere and the political situation may become difficult.

What we are doing now is to look for a partnership that allows us application of our experience on large scale. Submarine yacht projects have reached cost figures of 52.000 USD/cubic meter living space in the past. There is no need for a business plan expert to see that our project offering submarine living space at 331 Euro/cubic meter is a exeptional business opportunity waiting for the right cooperation partner to jump in...

 

 
Moved The Sub (Seasteading Comment)

 

...pretty pictures are wonderful, 'The stuff of dreams'.  Elmer, I see you've managed to move that semi submergable of yours closer to the water...

 

 

Yep, we moved that 200 ton baby  over 150m distance from the Hangar to the waterfront. We have it now right there sitting on the edge ready to get a final push and glide into its element. The water is 5m deep here she needs about 2, 5m to float out.

As expected the moment when we where on the point to tip the nose in - "interference factors" clicked in, as they always do in project management, when things come close to the finish line.

 

Although we are done with hull raw building within the original budget frames (331 Euro/ton) and we have successfully perfomed a movement considered impossible by many voices. There are still some battles to fight before we can invite to have a trip with a submarine yacht. Allies to help us with this task are welcome.

living in a submarine yacht ()

Comment on seateading...

I doubth like you, that there will be a lot of people that voluntaryly adopt submarine confinement as a desireable syle of living.

It may be one out of hundred who really would like to live disconnected from the surface, producing oxigen from the seawater wandering submerged and seperated from mankind trough the worlds oceans captain nemo style.

The typical owner would handle a submersible living space bubble habitat (i avoid the word submarine due to the misleading coffin perception) as a simple yacht that is in almost all of its aspects a yacht, just absolute storm safe, seasickness free, burglar safe, and maintenance cost free.

Like other yachties you would not be the whole day enclosed inside your boat. You would form part of a yachtie community anchored in the bay of a caribbean island.

In the morning you would row over to the beach meet with people from the other boats, have a beach grill, a coconut, a island adventure - you would only return to your boat to have a pleaseant night sleep in a king size bed and a freshwater shower.

There are differences in lifestyle to other yachties. For example when you leave your boat in the morning (all of your family - nobody wants to stay and watch the family home) you just close the hatch - so your living space becomes absolute burglar safe.

The other yachties always live a bit preocupied about their boat, is somebody breaking in to steal your nav equipment?, is the weather on the anchorplace changing smashing the boat against the reef?,  - so they tend to live "in sight" of the boat.

You on the other hand, when get an offer for this dream on week trip - take it - when you return you will find your stuff well protected inside your living space bubble - just exactly as you left it there - breaking in trough a hatch is like breaking into a banksafe - nobody can deploy the necessary (heavy industrial) tools on a anchorplace.

Another situation where your life is really different to a yachtie is when you are together with several sailing and motor yachts anchored in front of this pristine beach of a unhabitated island. Somebody has a radio and spreads the news that tropical cyclon Bertha category 4 is closing in. Now it becomes clear why this beautiful island was uninhabitated in first place - no save harbor miles around.

Some yachts rush out into the dark of the night to make it by the speed of their expensive engines to the next safe spot - just to find that it is cramped with poorly anchored industrial barges that tend to come loose in a storm and grind everything in their way to pieces.

Smaller yachts send the kids for the nearest hotel to be safe and go for the mangroves to bring out several lines to the trunks and fight it out. They can make it as long as the storm surge is moderate.

You on the other hand just close your hatch drink a coffee watch TV - no need to leave the anchor place. If things become bumpy flood your ballast tanks and lay your bubble some 5m down on the sandy lagoon bottom until the storm has passed over you. You and your family are safe as in a underground bunker.

You could take advantage of the shit weather and the sudden absence of all your yachtie friends and make a few miles to visit the next spot. You sail out directly into the storm - trim your living space bubble at snorkel depth - you leave the coffee cup on the table, you watch the weather the sea and ship traffic with your snorkel top camara - but your comfort is not affected by the storm.

Your live will also be a bit different when aproaching a cramped marina with no space for "another boat" - you will always be the "most exotic boat" that draws the attention and marina owners will love to asign you a nice place to stay - maybe for free. While it may be difficult to have privacy in a cramped marina on a surface boat - you close your hatch and you have it.

Your living space bubble will also be different in terms of aircon, comfort electrics, and loading capacity.

For example a yacht in the caribbean can spend dozends of dollars a day in aircon to make the climate below a sun heated deck just bearable. The seawater around your hull maintains the inside at 22 degee with no aircon need.

Yacht owners sometimes go crazy with the vibrations and noise of the small generator that keeps the battery and freezer alive. Noise dampening and vibration is most of all a function of bulkhead weight - bad news for "leight weight yacht outfitting" - you have your generator behind 20cm concrete - complete silence guaranteed.

Yachties are always short of loading capacity for freshwater food, tools, equipment.

You on the other hand have dozends of tons loading capacity this gives you not only the freedom of a much longer range compared with similar sized surface yachts - it also allows you to make a living as a trader - moving cold beer in hotel quantity to remote locations.

interior design of a submarine yacht
Any interior design seen in business jets or yachts is possible - plus a whole lot more - as you do not have strikt weight limits in a submersible living space bubble. So feel free to add a jaccuzzi - also there is no need to bolt everything down as the living space bubble stays on "even keel" under all ocean conditions this opens the possibility of using standard chairs and other off the shelf solutions form the standard housing market.

To get a picture how big the living space inside a submersible living space bubble is, how light comes in, check this video: www.youtube.com/watch - notice that light comes from above what makes interior design much easier than in a business jet (much less artificial light required)

We can do the hull for 331 Euro/ ton of displacement. The hull seen in the video above (18m / 200 ton) is for 66.200 Euro -

In general terms " semi/submersible living space bubbles " seem to be a great and economic way to independent mobile seasteading taking weather and wave concerns out of the equation allowing scaleability from mobile home size to city size.
