Cimmaron Tanker Tonnage

RFB Team · 03-25-10, 05:04 AM

The game by default has this ship listed as 7600 tons, which, upon looking around the net, seems to have been this ship's light displacement. However, in WW2, the Germans recorded merchant tonnage as Gross Registered Tonnage (GRT), which, according to the links below, would make this ship a 11,335-ton ship.

(Look at the T3-S2-A1 entry).

So, is it correct to conclude, then, that this ship should count for a lot more tonnage than is currently the case?

The ships were 553 feet long overall, 75 feet wide with a gross tonnage of 11,335 tons, deadweight capacity of 18,300 tons, and a full load displacement of 24,830 tons

If GRT was the one used then yes should be 11,335
I imagine the others are out also
And there was me complaining tonnages were too high already

Actually, the other ships are all pretty close to what they should be. The only other one I've found to be off is the the C2.

The Cimmaron class should indeed have a standardized GRT of 11,335 tons.

The only two specific listings I've been able to find (because they travelled once in a British convoy) are Chemung, which is 11,335 tons, and Salamonie, which for some reason they say was registered at 11,316 tons.

I have specific GRTs for a lot of C2s, but if it's randomized then SH3's 6200 is pretty close.

According to the game, the C2 modeled is the S-B1 variant. The game models it at 7600 tons, while the USMM website lists it at 6230 tons.

Oh yeah, the C2s. Some sub-variants are listed as low as 6100 tons, some as high as 8335 (the C2-S-AJ1). I too have 6230 for the C2-S-B1. Those are all civilian ships.

African Dawn 6507
African Star 6507
African Sun 6507
Bald Eagle 6178
Blue Jacket 6180
Golden Eagle 6180
Great Republic 6178

There are a lot more of them that I don't have the specific GRT listings, and a lot of other C2 classes I do; those are just the C2-S-B1s I have at present.

Interestingly, I do have one C2-S, Empire Curlew which is rated at 7101 GRT. It is the ex-Robin Doncaster, and its sister ships of the Robin Line - Robin Locksley, Robin Sherwood, Robin Tuxford and Robin Wentley - are group-rated at 7101. That is still a bit shy of 7600, but it may be where they got the idea from.

Well, personally I'm using the model as a stand-in for a generic large tanker, because, if we're being realistic, the Cimarron was a USN-only fleet repleshment oiler (when they weren't converted to escort carriers. So I've got the baseline tonnage at around 8000 with a variation of 3000 tons either way (the displacementvariation parameter appears to go both ways, btw, I thought it just added to the base tonnage). I've also renamed it to just 'Large Tanker'.

With the limited shipset, we've got ATM, I just don't see any point to applying realistic stats to the merchant vessels. IMO make them as generic as possible. Same with the Hog Island. Make it a generic small to medium merchant, until we get more ships.

That is a quandary, because technically these Cimmaron tankers were under the command of the USN, so the technically correct tonnage that should be applied to them would be their Standard or Light Displacement. However, since the game treats them as a merchant, and GRT was used when crediting merchant tonnage, the GRT tonnage value would be correct.

But yeah, right now the merchant variety in the game stinks, so it may be necessary right now to not be so strict about tonnage values.
