Any boat can be a submarine, once.

Adding a top to a boat and making it seal, not impressed (especially the shoddy craftsmanship).  Cramming air tanks and bellows to make it sink into such a crammed space, IMPRESSED!

Drug submarines are way way more advanced than this. Like a small country would be pleased to have one in their navy.

Is that back-and-forth "prop" really the best/easiest way to do this?  Figured some pedals driving a rotary prop would have been much easier and more reliable.

I haven't built a watercraft for, well - ever, just seems overly complicated.

Really?  A canoe is not a kayak and the word for going under water complete is 'submerge' not 'heat'.  The headline is rubbish.
 
2013-10-25 08:54:42 AM
Kind of cool, but hardly seems worth the effort.  Doesn't go much below probably 15-20 feet.  Very limited visibility and maneuverability.

Seems a lot of effort to stay dry when you could just buy a drysuit.

Meh.  If you're going to build a submarine, you should do like Peter Madsen, and build something like the UC3 Nautilus, or at least like his smaller, earlier effort,  Kraka.

Kraka was up for sale a few years ago, btw, and if I had the quarter million buck asking price, I would have snagged it, because it's got that classic German U-boat styling:

Now *THAT* is what a home-built submarine should look like.

A rotary prop would be really difficult to seal without a lot of room and weight. The way he's done this is quick and easy, works well - fish prefer it over rotary even. There's quite a bit of pressure at 30 ft. It's amazing the windows don't implode. There's a lot more to this thing I'm sure; the hood seal, front and rear ballast, air system - I wonder how he fit the mechanics of the prop/rudder through the area that must be the rear ballast. The whole thing is light enough to wheel off a trailer by himself. Carbon fiber is good stuff.

These are more like really low boats. Cool concept though. 5 knots is what a 30 ft sailboat cruiser would do. The thing probably punches through the swell instead of riding on top. Big storm? So what? 1500 gallons of fuel could move you quite a ways.

I was really intrigued by that thing as well. I have seen similar contraptions every once in awhile but that looks new to me. It also looks like he steers with it, simply by paddling off-center with it.

At 30 feet you can pop the hatch and get out easily. Not that building a sub is on my bucket list either.

I'm jealous. I tried designing a submarine from a 40 gallon steel barrel when I was about 12, but never got past the problem of needing 550 lb of dense weight to sink it.

This guy actually solved all of the engineering problems: air, tight seals, sink weights, propulsion, steering,  etc.

Kayak is another name for "water bicycle".

Ficoce: There's quite a bit of pressure at 30 ft. It's amazing the windows don't implode.


It's not amazing.  See the bubbles coming out of the top?  He's balancing the internal air pressure against the external water pressure.  So long as he does that, there is little stress on the windows, and you could have a paper-thin hull withstand the pressure.

Ficoce: A rotary prop would be really difficult to seal without a lot of room and weight.


No it isn't.  In fact, it's routinely done for human powered submarines.  Granted, those are free-flooding, but this guy is balancing his pressure using compressed air, so it shouldn't be too difficult to seal it:  A conventional stuffing box would be fine.
 
2013-10-25 04:37:09 PM
Human powered drug submarine.   As long as he doesn't run out of toot, he should be able to maintain about 35 knots underwater.
