I think I have mentioned this three or four times before. For logistics purposes, a “ton’ is either a “measurement ton” or a “Metric ton”. A gross ton or net ton is expressed in terms of 100 cubic feet of cargo space, but this is a tax measurement. Just think of how taxes are assessed against holders of millions, and you will understand just how utterly useless these numbers are in determining the actual carrying capacity of any individual vessel.
The actual carrying capacity of any individual vessel is contained in her builder/shipper/supercargo records. These are the data that shipping companies (and the various Naval establishments) used to determine who could carry what. Gross/Net tonnage was a lying shibboleth, as everyone understood.
What you could carry was a function of the ship’s “bale cubic” and its “Net Cargo Deadweight”. It had nothing whatever to do with gross or net tonnage.
AE has incorporated “bale cubic” and “Net Cargo Deadweight” in its determination as to who can carry what. The AE group has had the benefit of input from various Japanese sources that, despite contemporary assertions to the contrary, still exist. The AE cargo capacities are a mathematical functional aggregate of the “bale cubic” and “Net Cargo Deadweight” of the vessels at issue.
We know the bunker contents of the majority of ship classes and their design range. We also know how much of bunkerage was in deep tanks. We also know when, and to what degree, IJGHQ ordered reduction of deep tank capacity and it’s replacement with ballast. We also know when and to what degree various vessel classes were fitted out with strenghthened kingposts.
i am glad to hear this is the case for AE - but i am pretty certain it wasn't the case for Stock/Vanilla, and many mods seemed to have just used a percentage of the Stock to derive the shipping capacities of the ships. My original remarks (which provoked the post that led to this one) were pertaining to the current game, not AE.
Point of curiosity: Where on earth did you manage to get these shipping records? i've been trying to locate figures for total imports for various countries, and cargo handled (by port) without much success... to get individual shipping records for ships is really cool! [8D]
He didn't. 85 per cent of Japanese urban area was burned out. At the end of the war, the vast majority of records which still existed were destoyed by order (or even assumption there was an order). And the records were not to our standards to begin with. Nor can you read them easily - Japanese ships being the worst case - mixing English traditional and metric data - often confusing even experts in the era.
