Thanks, StaffAnon, keep us updated.

weighing roughly 550 kg and 220 kg,

The weight is kind of meaningless when underwater. There is an upward force equal to the weight of the water they displace in volume. That's why boats float, even if they weigh more than 550kg. Not trying to say it is normal, just pointing out that weight doesn't mean anything underwater.

Weight is not meaningless under water. Where did you learn science? Oh, you didn't.

Weight is meaningless under water. Mass and displacement are what matter.

You could pick up a 2000 lb weight with ease under water if it displaced 2000 lbs worth of water, right. It would be buoyancy-neutral. The weight would be zero. See how that works?

I can't pick up 2000 lbs whether it's under water or not. If you tie a concrete block to somebody and throw them in the ocean, they will drown. The water doesn't magically make the concrete block weightless. It will drag the person down and they will drown. This is cold, hard reality.

An Ohio Class submarine weighs 16,750 tons. Put it in the water and it doesn't sink, does it? You put it in the water and it lowers down until 16,750 tons of water is displaced by the hull. It floats. How do you go under water? If you add 2000 tons of water to the ballast tanks, making it weigh 18,750 tons, the sub will finally just barely slip below the surface. It will have neutral buoyancy. It will not go to the bottom, although it may drift there. There is no force making it drift up or down.

You're a fucking idiot. A submarine floats because it's hollow and mostly air. Fucking dickwad.

That's exactly what I just said. Not sure what your point is. The dry weight of a submarine when on land doesn't tell you anything with about difficult it is to lift when it is in the water. What matters is the overall density, not the weight. Density is mass divided by volume.

In my original comment, I merely said that the weight of missing object isn't really relevant to the question of whether it could be easily moved. You'd have to know the dry weight and the volume.

So I said "you're a fucking idiot," and you reply "that's exactly what I just said." I'm glad we're on the same page and can finally agree on something. Have a nice day.

Have a nice day.

You too!

Yup two airbags filled with certain gas attached and a mini sub no issues to overcome. Just need das i.q. Over 12. It was towed to another location.
