Why submarine yachting makes sense

save harbor beneath the waves
no hurricane season wandering
marina and harbor free operation
closed burglar and pirate safe
quiet living space at sea
drift dive operation
economic cruising
small engine
enormous range
lower slip and maintainance cost
lower hull building and engine cost

Save harbor beneath the waves

A surface yacht, needs to be designed to have the means to withstand adverse weather conditions or to reach a safe harbor before such conditions come up.

For a submarine yacht a save harbor is always near - just a few meters below. This has a mayor impact in the way how you operate a submarine yacht vs a surface yacht and in its cost o operation. First of all your tour plan is not limited by weather forecast and by harbors available along your route.

No hurricane season wandering

A submarine yacht as suggested at (www.concretesubmarine.com) exposes almost no surface of its hull to weather except a small sail (tower). So you can get the nose into the wind with a very small engine under any condition. On anchor place this means that the bow area is not lifted in any wave as it is the case in a surface ship which tends to bring tremendous forces to the anchor rig, which is the cause of anchor break out in severe conditions. A submarine yacht as my tested prototype brings very little force to the anchor rig - even in storm conditions.

For surface yacht you need to find a hurricane save place during hurricane season so yacht owners frequently move their ships. A submarine yacht you can be left on anchor place in a open bay during that time - no weather condition will damage or affect it - this is a mayor cost benefit.

Marina and harbor free operation

A surface yacht must stay in marinas due to its vulnerability to weather - a submarine yacht allows true marina free operation any place is ok to stay during your trip you can have a nice meal and a fine night sleep in open sea.

Closed burglar and pirate safe

A burglar can break into a surface yacht of any kind using a light hand tool - this is not the case for a submarine yacht. A hatch can be made with security features of a bank safe - break in with tools you can deploy on an anchor place is impossible. A act of piracy is also impossible a pirate can get on deck - but never into the hull.

Quiet living space at sea

The main reason why yachts stay a lot in marinas and very little time at sea is wave action. A submarine yacht can go to snorkel depth and is perfectly quiet in a minute without relaying on breakwaters. You can have a nice meal and go to sleep with no ship movement and security concern at all. Sub surface living space is the only quiet and safe living space available at open sea.

Drift dive operation

In July 1996 Ben Franklin a 130 ton research submarine made a drift dive of 30 days over a distance of 2700km in Golf Stream. This dive compared with a submarine balloon trip was performed without any engine use. Submarines that have a non-compressible buoyancy regulation can stay stable at certain depth to do that kind of voyage.

Economic cruising

No long distance surface swimming animal exists because this is not energy efficient. On contrary moving heavy streamlined bodies under water is VERY engergy efficient as the whale enegy model shows - those giants can swim 6 months with no refueling (feeding) and make distances of 10.000 miles per year. The power required to do so is about 20-40HP for a 200 ton body. See more about this in section energy economic submarine cruising ...

Small engine

So the recommendation for a engine in a submarine yacht must be between 2HP/ ton which is emergency power for a blue whale. This is already considerably less than you would have in a surface yacht but you should be aware that in a surface yacht you need a engine surplus to fight against a storm that could smash you against a reef. For a submarine yacht you could get away with a even smaller engine that would take you just to efficient cruising speed which is the range of 0.2 HP / ton of displacement. You may have a engine that is 5-10 times smaller than a similar sized surface yacht which means a mayor reducction in building and maintainance cost.

Enormous range

In a yacht submarine you have about half of the displacement as ballast weight. If you push it to the extreme you could replace all your ballast with diesel tanks. This would give you a tank reserve of 100.000 liter in a 200 ton submarine yacht. Which can take you 10.000 cruising hours at 3 miles/hour - So without taking the possible tank volume to the limits - you can have a tank size for oceancrossings in a submarine yacht.

Lower slip and maintainance cost

The concrete submarine hulls of our concepts are built according to the same rules that apply to submarine tunnels and bridge foundations - in the same way the only surface that is exposed to sal****er environment is a rounded concrete surface - therefore the maintainance needed is similar to a bridge foundation or tunnel - it stays in water for liftime - no dry dock, no painting, no sandblasting, - this is a mayor maintainance cost reduction compared to a normal yacht.

Lower hull building and engine cost

The hull building cost of our concrete hulls is less than 1/3 of building a comparable steel hull. The engine size you will build in is less than half of the horsepower you would have on a surface yacht of similar size. This is a mayor building cost reduction compared to a surface yacht.

One of the best uses for a submarine yacht is probably using it like a business jet, or a megayacht. Traveling worldwide while being independet of a specific place and go where business opportunities or needs come up.

Wil-- its like the billionaire effect isnt it??..people would build concrete hulls(such as myself) because its cost effective- this means that a family can own one..and not go broke (lets assume upper middle class income)..but 100 000 litres of fuel??..to fill up would be @ 1.33 cdn right now per litre, about 133 000 dollars for that much fuel!! the sdaying goes if you cna afford the expensive car--you can afford the expensive gas to run it...

the fuel costs there are more than my sub would be worth..not getting how this is cost effective...?? yes enormous range if you can afford the 100 000 liters..???
where i see cost effectiveness is in the D.E. propulsion since you are storing energy in batteries to be used later- hence you increase your range this way--if i want to go 10 000 miles-- and i burn 1.5 liters an hour, then @ an average of 4 knots(averaged surface and submerged running) then i get 2500 hrs needed so at 1.5 litres an hour thats 3750 litres or about $5000.00 in fuel! thats not cheap!
so, what would the ratio of battery running, to Diesel running anyway? I never figured this out yet...
lets *assume for every 24 hours running I use 4-5 hours of submerged electric propulsion...well than thats 4/24 x 100 = 16 %
so .16 x 3750 liters = 600 litres. therefore 3750-600 = 3150 litres a savings of- $780.00 to go the same distance. and less time running the diesels-

over the trip of 10 000 miles you save - 1600 miles worth of fuel. but that still doesnt seem like a whole lot to me. and an engine that would burn that much -would be small--i estimate my diesel (30 hp) to use about this much when running at about 6 knots submerged.
* i am assuming this is how long a stack of batteries would run the e-motor.
the more batteries the more charge time required running the diesel. so perhaps this is not correct and not a good example...????

Running a diesel 24/7 is not cheap, even if it is the smallest diesel you can find. The beauty of a snorkel boat concept is in the fact that your diesel can be very small - much much smaller than anything that a surface ship of similar size could have. In a surface ship the diesel needs to be strong enough to bring the bow into the wind during a storm. In a snorkel boat the diesel just has to overcome the windforce created by the sail area of the snorkel.

The diesel in a submarine yacht is ten times smaller, needs ten times less fuel. The high tank capcity is a option that you can take advantage of when you visit a country where diesel is incredible cheap - so you can get a year supply of fuel. You are in no obligation to fill this enourmous tank to start your journey.

If you are low budget you might use your diesel only the first day to engage the golf stream in florida then shut it down and opt for a pure drift dive ocean crossing as Ben Franklin (see log Benjamin Franklin drift dive) did - and start your diesel again at the end of the voyage when England comes in sight some 45 days later. The total diesel use for crossing the Atlantic would be a few liters.

Other than the Ben Franklin which was assisted by a surface ship to catch the golfsteam - a whale shaped boat with a small diesel can take the trip into the stream with no assitance.

. . . . . .

This "drifting snorkel boat concept" was also embraced by the Sea Orbiter project...

wil I heard that diesel is like 12 cents a liter in argentina??where else is it cheap??..never thought of that before--but again you make some good points...drift diving..whats the minimum dpeth needed for that? I thought you might have to go pretty deep..and what about a chart of the gulf stream--need to find that too..of course i may just be using it on the great lakes--however i do want to explore the arctic/north copast of canada too..if that goes well --who knows...

i would like to be the first independent homebuilt-self-propelled civil sub to go there...its my dream within the dream...

thanks for the info Wil-

i did post a question on how to see at night in the sub..?..how about depth and front views when its dark or the waters are dark..to keep from hitting a submerged object ,ship or anything else....?/whats your plan?

Submarine Yacht - movement in progress again

RE: Sub movement finished - Submarine Yacht

admin · Guru

As you know the project has experienced phases of work stop due to all kind of third party interference factors.

The shipyard went down, was sold and then rented to other firms. What was a shipyard when we started the project, is a crude oil load terminal now.

Officials familiar with the project went out of office and where replaced by new people not familiar with the project and taking hostile action against it.

The political situation changed (interdiction act).

All in all the how and intensity of "Media cover" has become a critical part of the project.

Until now we had maybe 1 out of 7 days where we could work in peace on the project.

So the time shedule for building went from initially planned 7 months to 4 years.

Things are in flow and i find myself frequently stepping out of the project and doing something else ( like organizing the repair of a container ship ) while i keep cooking the sub project on low level until third party interference allows me to go back and retake the project.

The important thing is that we made it inspite of all trouble and we kept it in the original budget after all.

For reasons you can imagine it is not smart to "publish anything that happens in detail in real time on internet".

The mere fact of "going public" can convert into "part of the problem very quickly".

So i will not give further details for now other than third party interference ambient has changed to a point where we can retake some works on the boat during november.

Basicly the hull is finished in raw building - and raw building of the hull was the contract for us.

What happens from there does not depend on me - it depends on the owner who is taking over the project now that raw building is finished.

And while the boat is on land it depends on third parties like the management of the oil terminal who is in charge of the terrain what can be done.

We have all the necessary permits, for the project, and we have done our part already.

So the question what is next - is like reading a cristal ball...it depends on circumstances i do not really have under control.

Sub movement finished - media cover

I consider Media as something like a snake, if you do not know ecactly how to handle it - it is better to avoid it. In any case try to choose the moment, the place and timing of your media engagement in a way that favors your cause.

The story that there is a hard working guy who builds something in a shed that might be considered a step forward in yacht technology on a low budget is just a "lame report" - for media purpose it is much better to report a "incredible new terror threat based on u-boats", or a "complete wacko who is good for a laugh".

Neither of those "pepped up" report versions suit your cause in any way and can on contrary trigger that a investors steps back from your project, that the official who supported your project because he found your effort interesting and admireable now takes a distant position.

So while you are in a early building phase media certainly have little probability to contribute something positive but high potential to cause damage.

This changes a bit when you get operational and the pepped up version of a wacko starts to be excluded by the obvious.

But still while the hull is black and raw (like mine in the pictures above) the threat version is on the table. So make sure you have yellow or white paint on it and a smiling dolphin on the sail so that the "threat version" also becomes a bit non feasible by the obvious.

Your ego may push you to "go media" much earlier than it is healthy for your project - try to avoid that.

When talking about media Internet is a kind of "media apart" Internet allows you to have your public statement in form of a website that can not be alterated and twisted by a "reporter".

So have a website that works as reference point for supporters.

You also might have blogs and discussion forums - but if you have discussion forums make sure that you have control to delete stupid comments from stupid guys. So avoid to have your discussion in a way that goes out of control.

You have seen me over the years having discussions of all kind you can see part of that when following the discussion link on my website .

The way as discussion with a "non informed public" frequently develop made me develop a discussion politics that includes to step away from "stupid discussion" much more quickly now than i did in earlier days.

If you discuss, and publish sub yacht info in a public space also be careful not to give advise to the wrong guys.

It would not suit your case if a printout of your "detailed tech advise on internet" gets found pined on the wall of the submarine building site in the colombian jungle -

I have been crucified many times for the "lack of tech detail info" on forums - but believe me it is a necessary thing to have that kind of "no how to build info to the wrong guys" politics.

Wow--never looked at it that way Wil...honestly i dont want media attention other than my youtube--but wow--you do make some very compelling ppoints to keep it under wraps...i will most definitely take that advice...

made the mistake of going back to boatdesign .net to discuss where to find a good hatch--big big mistake...i can be the first to tell you--nothing has changed and im done with that site--funny though i cannot find a place to close my account--apparently its like that song "hotel california"

"you can go anytime you like but you can never leave..."

same old idiots...

This is probably a good way to tackle the matter - have your stuff on internet in a way that only somebody who does a "really informed and precise google search" can find you - so you keep a door open for the guys that already went trough the basic stuff and know what they are looking for.

I always say that my potential customers, collaborators, and supporters are less then 0,01 percent of a random "public" - so placing yourself in a niche that only the indicated 0,01 percent will find, is a perfectly well suited media strategy.

The vast majority of the public is of "no support value at all" but creates a high potential of interference and trouble in a submarine yacht project so try to keep them out by "flying it below media hype radar".

the only thing is--i dont want to build and sell subs--i just want to use it..as my yacht..so i probably wont be setting up any sales dept. what i want is to get sponsorship to travel around the world in it...thats the end goal...

youtube is my platform--

but i could refer others your wqay as im sure ill have offers...ive already had some phone calls...and it isnt even built yet--only the frames are started...

interest is there -but im not a seller--just a guy who wants to live a dream...
