This, ladies and gents, is the UC3 Nautilus. World's largest homebuilt sub. Max safe depth - 100 meters, crush depth - 400 meters.
Displacement - 35 tons. Built by some Danish guy in his garage.

Said fellow is also working on a spacecraft now.

It came from SA:

So some things on that forum are likely NSFW. I don't view SA but a friend linked me to it.

Beautiful boat, much classier than I was expecting.

My gosh, that was absolutely amazing.

And to the other extreme, here is what a few friends of mine have been up to.

That's really cool! Although the retired sub Commander in one of the link photos has the expression, "What the hell have I gotten myself into?"

Very cool.

Video of the first dive. It's in Danish, here's a rough translation

Quote

00:00-00:10
The crew climbs onboard to the Nautilus.
Today the homebuild submarine will go under water for the first time.

00:16-00:19
Speaker: The submarines skipper, gives the last security briefings

00:31-00:39
Speaker: The ballast tanks are blow for the first dive of the day, that a camera crew for National Geographic also has come to cover, that’s why Peter talks in English

00:45-00:53
Speaker: Nice and slow, Nautilus seeks her natural element, but not everything goes as planned.

00:54-01:12
Peter: Reports! Whats happening?
Others: We listing now…more to the stern. Our angle has doubled.
Peter: No..it's not that much

01:15-01:19
Speaker: So there needs to be pumped extra water into the forward ballast tanks, but it doesn’t go as fast as Peter Madsen had hoped

01:21-01:24
Claus: It takes some time
Peter: It takes a half %Â¤# hour!

01:30-01:38
Claus: I will tell you when I see something happening
Peter: Yes, please report
Claus: And nothing has happened

01:39-02:15
Speaker: Here she surfaces from the depth again. The disaster did not happen and Peter has an idea of how the balance problem can be solved.

Peter: We have just surfaced from the first dive with the Nautilus. And skipper here is getting an orange. Everything went well, but vessel is tight, but we have a trim problem along the vessel. The vessel is heavier in the stern than the bow and it doesn’t take much for that to happen….only 500kg. Because of this we will have to move the vessels point of gravity…we cant do that now, but we can simulate it by moving all of the crew into the control room.

02:19-02-23
Speaker: Now it's time for the day's and world history’s second dive.

02:40-02:42
Speaker: Its not routine yet!

02:50-02:57
Speaker: Again the bow is higher. And the Peter's alternative plan has to start.

03:18-03:20
Speaker: Also us journalists, will have to act as deadweight.

04:11-04:22
Speaker: And then Peter would to ascend fast.
Peter: I will go up level and then we will do the final bit.
Speaker: Also to give the people on the surface a surprise.
Peter: Blowing for and aft!

04:28-04:32
Peter: Oops, we surfaces with the stern first…

04:44-05:05
Peter: For a new ship and for the first dive it went very well. We have to move some ballast for it to act like it should and we will need to finish it with its sensors, its periscope, hydrophone and stuff like that, so it can sail unassisted.
Speaker: Peter Madsen and his crew estimates that she will be fully operational by spring 2009.

amazing! although terms like "galley", and "head" would give a slight bit more credibility to their nautical prowess.

I'm sorry, if you build three submarines in your garage and sail them at sea, the requirement of using naval slang is waived.

Where are the deck gun and torpedo tubes? There must be a convoy of merchant ships somewhere they could go after? Somali pirates maybe?

Manedwolf · « **Reply #12 on:** November 10, 2008, 09:49:14 AM »

That is so freaking unbelievably cool.

41magsnub · « **Reply #13 on:** November 10, 2008, 10:21:42 AM »

For a chuckle read what the filter on that forum did to people's comments. As an example.. "that is so gently caressing cool"

Viking · « **Reply #14 on:** November 10, 2008, 11:22:34 AM »

Now that is FRIGGIN AWESOME! I vote that we recruit these folks to our pirate hunting expedition!

Gewehr98 · « **Reply #15 on:** November 10, 2008, 02:13:17 PM »

Das Boot is useless without torpedo tubes, or at least a bow spar with a detachable limpet mine.

He'll have to adjust his technique to trim the boat - running crew members fore and aft isn't the most efficient.

Manedwolf · « **Reply #16 on:** November 10, 2008, 02:38:20 PM »

If they have an escort vessel, I would spraypaint some beer kegs gray and put them in a line at the stern, just to make people wonder.

I took a boat out of a major refit in '84 getting the trim right the first time on the first dive was a major cluster flop.

Running crew members fore and aft can be very fun though when you have a new Diving Officer on his first solo watch. Particularly if the XO is in on it.

Gewehr98 · « **Reply #18 on:** November 10, 2008, 03:05:20 PM »

We did the same thing on the WC-135. New right-seater, plane on autopilot over the Pacific at FL 35.0, several hours of basically nothing until we arrive at Yokota, Misawa, or Kadena.

The left-seater checks off and says he's going aft to get coffee, leaving the new guy watching the gauges, monitoring radios, and reading the newspaper. But he's not getting coffee - he's passing the word around that everybody should slowly, one at a time, head for the aft galley and stay there until given the signal.

The signal cues everybody to rush forward to the flight deck, all at once.

The autopilot pitch axis senses an abrupt nose-down change in the aircraft's attitude, and immediately goes into an emergency climb while sounding alarm horns. The yoke comes back smartly into the right-seater's lap, and if he was reading the newspaper, oh well...

I thought you were going to say you took the parachutes, all hid somewhere, then tripped the exterior door/pressure alarms.

Gewehr98 · « **Reply #21 on:** November 10, 2008, 05:48:41 PM »

Nope. They took the parachutes off that particular platform many years ago - otherwise we probably would've done that particular practical joke. The common theme in Air Combat Command with respect to the RC/WC/EC-135 fleet is that it's safer to ditch the plane or belly land it than try to parachute out.

The crew entry hatch under the C-135 airframe's nose has a 4-foot "spoiler" that's deployed with compressed nitrogen when the "chinning bar" was pulled down to jettison the hatch for emergency egress. It was supposed to deflect the slipstream enough to enable a person to cannonball out somewhat further before getting blown back. Boeing supposedly did some tests with dummies, and the deflector didn't help - they bounced violently along the aircraft's belly, taking out nearly every VHF antenna enroute to the tail. Instant Veg-O-Matic! The same went for the two overwing hatches and the aft emergency escape hatch - the hapless individual would hit the horizontal stabilizer's leading edge. So they took away our parachutes. "Y'all should ride it in!" Gee, thanks.

However, Air Mobility Command, Air National Guard, and Air Force Reserve KC-135s still have their parachutes. Go figure.

did you guys see video of the dummy tests?

Gewehr98 · « **Reply #23 on:** November 10, 2008, 06:48:40 PM »

I would imagine they were available had I asked, but I didn't want to.

You got any?

cassandra and sara's daddy · « **Reply #24 on:** November 10, 2008, 07:12:10 PM »

nope! i think it might scare the recruits
