Suggestion: Would adding Volume measurements to cargo help differentiate ships?

Good morning everyone. I've been lurking on these forums for a while, reading up on the gossip and ideas floating around on how it seems certain types of ships that are specialized aren't really that good at their jobs. For example, the Type 9 gets out-cargo'd by all the other ships in it's weight class currently. I've been hearing lots of different ideas, like adding specialty 'cargo' only racks to the ships and other things so that cargo ships become more useful, but I've been thinking about something different. On the Reddit there was an arguement about the Type 9 being so much heavier than the Anaconda despite being a similar size and the question of where all the extra mass is came up.

Thinking about how cargo is handled currently we don't just worry about it's weight, like we do in Elite now, but also how much space it takes up. I mean, looking at a ton of gold compared to a ton of animal meat. Gold is really heavy per volume, and a ton of it wouldn't take up nearly as much space as a ton of beef.

So I'm wondering if maybe the way cargo is handled should be switched up a little. Make it so not only the weight is a factor (which would affect things like thruster speed and jump range) but also the volume. The Anaconda may have enough power to move some 200 tons, but maybe not enough space to do so depending on the cargo (as it is a multi-purpose ship it would have designated space for rooms for the employees and other things needed for a jack of all trades), which would give a ship with a large cargo bay more opportunities for bulk shipments. I'd guess something is already being calculated since the mass of the ship and it's cargo is already taken into account for figuring out jump distances with the navigation computer, so hopefully such a change isn't too drastic from what we are already familiar with.

What do you all think? The boys and girls over at Frontier, any reasoning why this may not work quite so well?
 
I'm not interested in making it complicated, but both more relate-able and fair. When I'm loading a moving truck to get all my stuff from my apartment, I'm more worried about how much will fit in the cargo space instead of how much weight it puts on. (The manufacturer of the truck as figured out how much weight will work on the axle of the cargo space and made sure the size calculates for me)

Yeah, adding a second measurement could mean a bit more complexity but I'd assume some of this is already taken into account since the weight is being turned into Mass for the jump distance calculation. Maybe instead of having 2 measurements (weight and volume) we switch it to just the mass of the cargo (which is already a measurement of weight and volume, so still one statistic for pilots to worry about).

Cargo containers can carry Hydrogen Fuel - that means that they can carry 1t (tare) of the least dense substance that there is (1t of hydrogen takes up 14.12m³ as a liquid and 11.63m³ as a solid) - so each cargo container has a nett volume of somewhere between 11.63m³ and 14.12m³.

Our ships FSDs and thrusters are weight governed - so permitting a ship to carry cargo by volume rather than by weight would quickly end up in not being able to go anywhere (and would probably have structural, centre-of-gravity and radius of gyration issues for ships).
 
Firstly, 'real world' comparisons are meaningless, since we're discussing a science fiction computer game.

Secondly, adding a volume component massively increases the complexity of trading, for no actual benefit.

Consider a Sidewinder, with a 2t cargo hold. Adding volume simply means that low density commodities can't be carried because they take up too much space. Equally, a T9 with 500t (or whatever the limit is) will either have vast amounts of wasted space (limited by tonnage) or be able to load so much cargo that it can't jump anywhere (limited by volume).

Right now a Cmdr can look at the Commodities market and know exactly how much of each commodity they can carry. Your idea blows that simplicity completely out of the water.
 
They are called Traveller Displacement Tons, and they are the volume of one ton of liquid hydrogen: 13.5 cubic meters. 2 x 1.5 meter squares, each 3 meters high. :)

Deck plans, anyone? :)

Ah, you had the scientifically precise answer. :)
