I want to build my own submarine any idea how?

[QuantumTyphoon]

I have my open water diver certificate and I have not dived more than 120 feet. I'd like to explore depths exceeding 300 feet without nitrogen narcosis or dive bells. I'd like a crush depth of 600ft no less preferably. Either towed (battery) or battery and diesel no preference. I have no need for periscopes. Sonar would be handy for detecting boats and fish and the bottom. A couple view ports would be nice, one on the top and one near the bottom. Capability of attaching external camera's in their own pressure safe compartments.

For the technical stuff what do I need to learn? I can't imagine that simple plumbing knowledge will help much, or home depot will provide me with anything I need to acquire for the project. Who should I ask for help? I need to find out how to build ballasts. pumps that don't freeze when in cold water and at depth. The deeper you go the colder it gets right? I'd like the capacity of the boat for 2 people maximum. How do I go about sourcing the components I need to build the submarine? I live in Saskatchewan, Canada. So I'm not near any ports where I could just walk in and start asking questions.

Am I right in thinking along this train of thought ?

Will my submarine have a keel to keep it from rolling in rough sea's like ww2 military submarines had. Would adding a keel compromise the maximum depth, both in cost and strength. I need a coning tower to keep water out of the top hatch? How do I shape the metal? I can't do that myself I have to get a manufacturer to do that for me ? Should I ask a tank maker to make me a tank. But how would I calculate the variables when cutting holes for pipes example: ballast tanks, pipes, propeller shaft, etc. After cutting a hole in a tank or some other pressure capsule how do I reinforce the hole from the inside and the outside? Could I make one with a budget of $60,000 Canadian?

Mod: I don't know where else to ask this question. And I did some searches but I didn't find any info, except for toy models and such.

Wouldn't it be better with a diving bell

I guess it would be easier to build such a thing like a Diving bell.

You could build a submarine for $60,000, I'm sure most of the narco "subs" cost less than that. But keep in mind, there's very little margin for error with negative buoyancy craft. One thing goes wrong and your dead.

Ditto. I have no idea how they calculate crush depth? I guess you can only dive as deep as your weakest point? You get a low quality part, install it wrong, or bad engineering....

It would be easier to build some sort of a Diving bell-here he has multiple choices-From fully closed to fully open.

Here it is the thickness of the material-most likely steel which decide how deep he can go.

I don't think those NARCO subs are truly submarines, instead I think they're designed to travel just below the surface with a tiny cockpit sticking out of the water. A much easier craft to construct I'd say than a true submarine.

Can narco subs go underwater?
Image result for narco subs not true submarines
Virtually all narco submarines interdicted at sea have been more correctly termed low-profile vessels (LPVs). Also known as semi-submersibles, these are craft designed to run exceptionally low in the water to avoid detection. But they cannot fully submerge.Nov 16, 2020

I wonder if George Soros has a mega yacht? hmmm

I wonder if George Soros has a mega yacht? hmmmNOT ANYMORE: http://www.hisutton.com/Fully-Submersible-Narco-Submarine-Apr-2022.html 'Arauca River Monster' Just when our eyes are fixed on the Ukraine War, a narco submarine surfaces on the other side of the world. It’s been relatively quiet on the Narcosub front these past few months. But the one found last week in Venezuela is one of the most significant developments for some time.

A narco submarine discovered on the Arauca River is unusual and significant in 3 ways:

Firstly, it is a fully submersible vessel (FSV), which is unusual in itself. These can submerge like a navy submarine, although only to shallow depths.
This is the first time a FSV has been caught ‘in the act’. Normally they are found while still under construction. Unlike their semi-submersible brethren (low profile vessels -LPV), none have been interdicted at sea.

It was found on an inland river sailing between Colombia and Venezuela. This may indicate a variation on the known transatlantic smuggling route.

On a serious note, if I had a boat load of cash, I'd try and build Simon Lakes' "Protector".

from a website dedicated to submarines I was expecting more. Ironically I did find information indirectly through this website and others from modders who don't mod anymore.biblio.org/ and the hsna.org has a lot of information that explains what I need to design a submarine and build one. Maybe I should leave it be. But how are you guys so stupid???? Your like 10 year old children. No that's insulting to ten year old children. Your like 6 year old children. You scoop up some links anyone could get in under 2 minutes. In the silent hunter 3 manual it states that the allies had invented 2cm radar which could detect any snorkel or periscope that was higher then 2cm. That was the end of the 1940's. The whole drug boats with snorkels is either made up or they're made by peasants with the most basic knowledge. For years the only way for the Russians to get close to American soil was by keeping submerged. But now evidently someone with a budget of ford mustang can get past the anti submarine forces of the U.S Navy. Yeah right. This forum had turned into a joke. Bye bye jokers.

Well NONE of us here is expert in constructing a submarine. We had an honoured member some years ago-He had built his own sub. Well due to a story well known around the globe he is it not anymore. 'cause you could have asked him for the blueprint to his Nautilus UC3.

Secondly this is Subsim a forum where stay on target is...

I gave you some link after having made some search for blueprint to submarines. Since I'm not an expert in this field I don't know if they can be used as a guideline that is.

Well, if you're trying to get critical information on how to build a submarine from an internet forum.... please keep us posted on the progress of your submarine.

Most importantly, don't forget to install scuttling charges.

The Hunley was a pretty decent design. You might try building one of those. It was green before green was a thing too. :D

[Aktungbby]

well considering that green design killed 3 crews, things could get cranky...if U had 7 expendible friends to man the propulsion that is:03:

Hey someone posted some weeks ago a picture of a Russian sub which was a wreak.

This made me think that USA or some other western Countries may have old wreak of a sub somewhere. Which he can buy.

Markus one wreaks artifacts and scrap metal from wrecks on the seabed :haha: the classic case is still the Glomar Explorer's retrieval of the Soviet K-129, in part or whole, from the seabed during the Cold War imho.

Wanting to build a sub able to dive to 200 meters, and speaking about how easy it is to build a narco sub.

With 200 meters/600 feet crush depth a pressure hull would have to be made of thick special alloy steel, probably with internal braces. Portholes as well as all openings in the hull for pumping water or propshaft seals are weak spots and should be avoided or kept to a minimum.
May consider to make the boat lighter than water, probably with some exterior ballast weight that can be dropped without using pumps in an emergency.
Pumps able to empty ballast tanks under 200m pressure will have to be special ones, should also be capable of more due to clogging, unintended greater depth etc.
Salt and fresh water have different density and viscosity. Consider silt or floating stuff entering the pump intakes and so on. Pumps fail all the time.
Leaving the boat at more than 30 meters without diving suit will probably kill you.

You did not specify salt or sweet water, speed, loading of batteries and a hundred other things. But my chrystal ball tells me that you cannot be that old, at least your reaction is childish b.t.w. :yep:

[mapuc]

^ I knew there are thousands of things you have to take into account when constructing a sub and especially if you want to take it below 200 m.

My best advice would be that he contact some submarine constructor they know what is needed-If he has the money for it.

This is why I said it would be better with a diving bell-Easier to build and doesn't cost so much and due to it's form it can withstand high pressure on all side which mean he can go down to and perhaps below 200 m.
(Here I'm thinking on a all closed bell)

Certified Joker ? That's a complete understatement. :haha: I purchased a Camaro with a T roof that was in decent shape. That is until the engine spun a main bearing because the previous owners didn't know that you should change the oil " Once in a while ". I found another engine that will require a rebuild. A builder I know that builds race engines will be doing the honors of rebuilding it. My lady asked me why I wanted the car in the first place and I politely responded, When my midlife crisis happens, I want to be completely ready. :D

She Rolled her eyes and told me that will never happen. She told me that to have a midlife crisis, I would have had to grow up in the first place. Maybe one day. :haha:

This website is dedicated to those with an interest in just about anything with a nautical theme, especially submarines. A great number here at Subsim have extensive military, technical and university backgrounds. Even without some of those things, I have found them to be an intelligent bunch with diverse interests and backgrounds from astronomy to mechanics and everything in between. From what I know of some of our members and their experiences and education, I would " stack " them up against anyone in the world.

With the happenings in the world right now, it might be helpful for you to develop a sense of humor. You might live longer and not be so stressed out and risk offending those around you. Most here have a sense of humor. Try it, you might like it. :yep:

You act as though people here build submarines all day. Perhaps some do in their respective jobs and positions but they would never tell you that. Have you heard of the term, " Silent Service ? " I know some here at Subsim have served on Submarines, both nuclear and diesel.

Please tell me you're not so naive as to believe that anyone with a military back ground with A technical perspective that includes building submarines is going to share that with someone with the mentality of a temperamental child or anyone else for that matter. Do yourself and everyone else around you a favor and grow up.


By the way.

from a website dedicated to submarines I was expecting more.Your like 10 year old children. No that's insulting to ten year old children. Your like 6 year old children. You scoop up some links anyone could get in under 2 minutes.

Quote : Your like 10 year old children. Your like 6 year old children.

The proper grammar is You're like a ten or 6 year old, not your. You're is a contraction of you are.

I think you should go back to school and take a refresher course. If you have gone to college or somewhere else, get your money back. It didn't help.
