When ships are described as a "10,000 ton cruiser" <- example....what does that mean? The ship weighs 10,000 tons? It displaces 10,000 tons of water? And why aren't they just described in length?

Length doesn't give you an idea of the volume while tonnage does.

It means it displaces 10,000 tons of water.

Any floating object displaces it's own weight in water. A 10,000 ton ship weighs 10,000 tons and displaces 10,000 tons of water. Both are correct.

This only changes when a ship weighs more than the water it displaces: it sinks.

It's not that the ship weight more than the water being displaced. It's that the ship stops displacing water.



Same thing. When the amount of water the ship displaces becomes less than the mass of the ship, it sinks.

Does the tonnage rating change when it's empty or full?

Does the tonnage rating change if it has a full load of chicken feathers vice a full load of lead?

Gross tonnage is a measure of the total internal volume of the ship.
Net tonnage is expresses a merchant vessel's earning capacity and gives the internal capacity of that part of the ship available for cargo or passengers.
Thames measurement tonnage was used for smaller vessels and worked to a formula: (length - beam) x beam x ½beam / 94
Displacement tonnage is normally applied to warships and equals the actual weight of a ship complete with crew, fuel, stores and water.
Light ship tonnage measures the actual weight of the ship with no fuel, no persons, no cargo, no water on board is not usually quoted.
Deadweight tonnage is the weight of cargo, stores, passengers etc. which when added to the weight of the ship's structure and equipment, will bring the vessel down to her designed waterline.

Which is why torpedos, mines and near misses tend to work better than hits when sinking ships. Letting water in below the waterline works better than letting more air in above the waterline.

and as long as the ship weighs less than 10000 tons of water it will float.
