Build your own submarine for £60,000

I think this is perfect for the "Mad House" section:

Remember kids, if you get hit by another submarine, you've got nowhere to go, you're trapped inside. Priceless.

The thing I find wierdest about that is that it cost 60k to do....presumably the internal mods must have been extensive as the outside just looks like a normal barge with a couple of curved tin sheets and a lot of gray paint.

On another note, it's surprising that there aren't more DIY submarines around (I haven't researched so there may be loads) after seeing some of the nutters that build their own planes or helicopters.

In a similar vein:

Ugandan space programme!

Sounds about as credible as the Petorian space project!

the problem with building a sub is that it needs to be very heavy to be able to take any significant volume of air down with it, and also the batteries would be costly. Plus, its more dangerous than many other activities! I've often fancied making a simple one, but its just not worth the effort considering you couldnt actually use it.

Don't they use compressed air? The density of the air doesn't matter (for bouancy at least) it's the volume that would require balancing...

The weirdest thing about the report is was that is his wife?????? old captian birds eye must have attracted her with his big periscope! Dive, Dive, Dive.

Eh? She's younger than him but that's about as far as the good points go......

ETA, when I made my earlier comment the vid wouldn't play so I could only see the outside. Parts of the inside look quite good but definitely not worth 60k IMHO

No oil painting but half his age, so in my book thats pretty good going.

how about this one http://www.vulcaniasubmarine.com/KRAKA.htm

As usefull as a plane that can't fly

compressed air is just to push the water out of the tanks, to resurface. Since water basically floats in water, letting water into a tank only offsets the buoyancy provided by that tank when full of air. It cannot help sink the air in the habitable part. If you want to take down 10 cubic metres of air with you, the vessel, on dry land with ballast tanks empty, must weigh at least 10 tonnes. If you then want to be able to make it float 50% out of the water, you need to add 5 cubic metres of ballast tanking below the waterline. Flooding these just takes you back to neutral buoyancy, approximately and with some room to argue!

Anyone who's been on a proper submarine would not be wanting to ever go in a home built one!

Even the real/proper ones are a very very rubbish place to be!

it's not designed to submerg, just to look like a submarine

A man has turned his canal barge into a replica of a submarine to mark his 50th birthday.

Richard Williams said the work cost almost £60,000 and took about three months to complete.

The barge cannot be submerged but does sail along the Leeds-Liverpool canal, with Mr Williams often welcoming people on board.

He lives on his "submarine" with his wife, Laurel, and their three dogs.

Yeah, that makes sense - it was the bouancy control I was thinking of - the life support stuff slipped my mind completely!

Seems mr williams has found himself a spot of bother! I happened to go on his sub last week because its moored up outside the Royal Armouries.
