it was manufactured upside down because it's easier to lay a big steel plate and weld it rather than trying to lift all the big heavy plates and support them without flex while a guy stands under it and welds each plate. the prop and shaft were not installed yet due to the force of impact as it flops over would bend the shaft. no dummies here
There’s some funny comments on here! But the truth is it’s a lot easier to weld the hull plates with it upside down so it’s a common practice. Though the flipping is usually done on land, I’ve never seen it done in the water before.
Up to a certain size, it's much easier to build a boat hull upside-down. You can lay the flat deck on a shop floor, or on simple supports, and build up from there, with no need for expensive, custom framing, and with minimal need for overhead welding. Ask anybody who's built their own boat, and they'll probably tell you they did it upside-down.
My father many years ago used to turn barges over when afloat by partially flooding them passing ropes over the hull to the far side and towing them broadside on The deck edge nearest the tug would go down the water inside the hull would rush down and over it would go No cranes just a tugboat
I worked in a shipyard in San Diego (not National Steel) & we built tuna seine 1200 ton net load and we launched the bottom of the ship upside down and then flipped it hauled it back onto the building ways and added the top and relaunched several months later
This would have gone a lot better if they'd had all these RUclips experts there to assist.
NOOOOO!! Flip it back to the way it was. Looks like a futuristic hovercraft.
Next time remember: If the writings on the blueprint look strange and are difficult to read... you're holding it upside down.
Very interesting. I am amazed how shallow the draught is.

Oh my goodness!!! This is the strangest thing! Well, you never cease to learn!

Upside down it looks like the latest state-of-the-art military Stealth Warship.
For a second there, I thought they built a new USS Merrimack.
Sound costs extra.
That worked out nicely.
Hey guys look over here, some paint is drying.

They had the plans upside down all along!
Hats off to the guy who noticed somethin wasn't quite right.......before they put on the Deck.
I agree with Max; I would have expected the prop and shaft to be installed prior to flipping it.
I wonder when they first realised they'd built it upside down.
Absolutely fascinating that they launch it upside down then flip it.
