GURPS Spaceships, upscaling sizes

[ravenfish]

Per Spaceships p.17, "steerage cargo is pressurized and climate-controlled," so there's probably enough life support to maintain the atmosphere at least.

The rules on depressurization imply that all cargo space is pressurized and only compartmentalized from the rest of the interior on large vessels.

Yes, but it does not count towards number of people the life support can handle. That is strictly 4 per bunk room and 2 per cabin, so that would mean that the actual air-regeneration systems are part of those "rooms", while all the rest have HVAC and pressure support.

Normally, you round up on SM, so that would by +12 (which is why I use the fractional ones)

Physical size, at 294 yards, it would be up to SM +13 according to that. You could call it SM +12, since it was long, but it was very boxy...nothing like something like a fast battleship (Iowa classes were as much as 60k tons, but a little shorter, and a lot more svelte).

Yup. Guns and armour are heavy, and so is the structure to support them.

Comparing the numbers from Wikipedia, Titanic was midway between Iowa's standard and max tonnage, almost identical in length, and slightly narrower abeam and had lesser draft.

But Iowa had a clipper bow and raked sides, whereas Titanic was a floating apartment building (or, being British, a block of flats).

In my games I assume that steerage cargo does indeed contain long term lifesupport for four or short term for 15/5 ton chuck as the designer wants and that accounts for the extra mass...

Given the difference between life support and non life support habitats, that doesn't seem to add up.

TBH I'd guess it doesn't really represent anything except that 5 tons per cabin was the most they could give without the SM+5 habitat turning into a bag of holding...
