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?

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.
