The tonnage cost is far too high

Not sure what you mean with the "cost" bit.

Your design costs 11,248 tons to build, because the 'cargo' is simmed as armor that is there all the time. Where cargo is simmed as additional bunkers, the permanent structure of the ship is not burdened with the additional weight; the light displacement is far lower.

Actually it is 3098 tons as I indicated a few lines lower and that figure is only slightly more than the 3380 short tons (= 3017 tons) given on the Wiki page of the SS John W. Brown for light displacement.

My error - but that highlights the confusion that can flow from some methods of simming a merchantman.

If we could gather full participation and approval, then I think it might be a good idea to at least discuss it.

Wiki is rubbish when it comes to Japanese merchant ship data.

Yes, when there's data for Japanese merchant ships at all. However, I had found a website some time ago which listed quite a number of the classes of Japanese merchant ships during the war, together with some photos and specs. Like I said, if I encounter it again I'll link it to you; not sure if I bookmarked it or now.

Nihon Kaigun comes to mind

My kanji is far too out of date.

The first is courtesy, the second essentially is so that we don't have a situation like we had awhile back where the US had no modern fighters.

And yes Walter I was ribbing you, I would rather not have Ford, GM, Chrysler, and AMC be the victims of "unitended acceleration" they have enough quality control problems as it is.

All that being said I don't want a deluge of people wanting to use US stuff either .

This is what's in the Springstyle notes regarding merchant ships...

## Quoted

Transports and merchant ships: The "miscellaneous

weight" feature of the program allows weight to be reserved

for cargo capacity. So to give a ship a cargo capacity of

10,000 tons, simply provide that much miscellaneous weight.

Provide at least one gun, if only a .30 caliber or

9 mm (0.9 cm) weapon. Otherwise Spring Style will list

"0 x 0.0" guns, which looks silly! (*)

However, note that cargo ship capacity is normally

listed in gross registered tons (GRT), which is a measure of

volume, not weight - 100 cubic feet of enclosed volume =

1 gross registered ton. (However, registered tonnage is

usually about the same magnitude as weight capacity.)

To determine gross registered tonnage, make the

following calculations:

1) Multiply "loading submergence" (listed below the weights

table in the ship report) times ship's freeboard (listed

under hull strength in the hull characteristics section.)

2) Add the result to normal displacement.

3) Multiply by 35, then divide the answer by 100.

This is the gross registered tonnage for a typical

cargo ship.

Also, for civilian merchant ships, divide crew and

damage survival values by 10 - they have small crews, and

lack the extensive compartmentation of naval ships. For

naval transports, divide crew by 5 but leave survival

values unchanged. Adjust your ship report accordingly;

I compute and list Gross Registered Tonnage on the line

below displacement.

For armed merchant cruisers, I suggest simming

without the increased armament first, then adding the

armament and reducing miscellaneous weight (cargo capacity)

as needed.

(*) only applies to Springstyle. Not necessary with Spring Sharp.

Maybe Khranitel will be charged with sexual harrassment.

If I were to cut the BC and cut beam to allow for bulges and change to 3x2 380cm guns and then do some tweaking, I'm pretty sure I can improve those aspects.
