Visual Size Reference: 1dt and Stateroom

wbyrd

SOC-13
Okay one thing i had to exlain when I started teaching people Traveller was the concept of a displacement ton when we got to ships....It's a bit tricky since a lot of people have issues with visualizing a solid structures, and spacial relations in their head.

so while playing around I decided to make myself a visual representation of the pace compared to an average human.

1dt_cube_by_wbyrd-d9ilke7.png


The cube is 2.4x2.4x2.4 meters, (7.8 feet) ( roughly one displacement ton)

Human 1.75 Meters tall ( 5'8" -5'9")

stateroom 10x12x8 ( 3.04x7.3x2.43 meters) 4dt ( not same layout as deck plan rooms just a rough visual size reference.)

the stateroom would be large enough for a short stay for one person. with some leg and head room. If you take away a 1dt cube as a fresher you still have a good bit of room for furniture and bed...larger than some apartments I've rented :D

a drop ceiling, partition, or raised floor would give space for plumbing, and other equipment such as life support.
 
Maybe I'm misunderstanding what I'm seeing, but if the blue box represents a stateroom of 4dt, shouldn't it be one cube larger? To me it looks like the grey box is 1dt, and the blue box is about 3 of the blue boxes.

It does look off but I triple checked my math


the dimensions I have come up to 3.85 Dt which was close enough for a rough guide....but then again I have been off before...
 
The classic deck plan footprint of a ton is two 1.5 square meters, so 3 meters by 6 meters for 4 tons would be a good comparison point.

It looks off because it's not mathcing the standards used in various deckplans...

CT, MT, most of T4, T5, and most of TNE, the Td (Ton, Displacement) is usually 1.5m x 3m x 3m, on a 1.5m gridded plan shown as two squares.

In TNE, it was 2m x 2m x 3.1m, on a 2m grid (to match the combat grid scale of Twilight 2000).

GT uses hexes of roughly 1m face to face. (3', actually). I don't know the standard height (Checking GT, it's "8-9 feet"), and the advice is 6x 3' squares or 4x 3' hexes.

See above :D I never intended it to be anything more than a rough shape to give people an idea of what a D-ton was compared to a person.

It was just a rough visual reference I knocked out while listening to an HP Lovecraft audio-book...were lucky I didn't accidentally create a 7th dimension rift in there...and thanks for the info much appreciated

That's a huge room for a spaceship. Yowzer.

I always factored in their share of hallways and commons space.

A really good form factor to go off of is sleeper/private railway cars, including the folddown bunks, rolling kitchens, eating and observation space.

The plans a good for references; they would be "great" with dimensions. Of course we have bunks there, have all been in trains, and most of us have probably slept aboard, so we have a feel for them.

However, if we are to use science to remove the scat from the problem (GREAT FLICK!), then dimensions are called for.

On a modern boxcar, the interior width is about 9.5', which corresponds to these, with thicknesses for partitions and the odd bulkhead, is about 10', or 3.0 m (two CT squares). So if one superimposed a grid over this bad-boy, it would look something like this.
 
And the patent that was key for Pullman to fit so many beds in a small space (and therefore profits)- the double bunk with turning seats into a lower berth and a fold down bed above.

Depending on the vessel, referring here more to private sector-commercial ships, the individual stateroom may not reflect a standard floor plan or even size.

On smaller starships like scout-couriers or such, dedicated cabins might be 'regulated' to senior officers or exclusive to the captain themselves.

I've always seen such vessels short of available space to have capsule hotel-style berthings and the 'saved' displacement pooled into larger common areas. Mind that does generally require communal fresher facilities in likely 'squad-bay' arrangements but again, more 'elbow-room' for the galley or crew lounge.

One last bit, any single occupancy cabin could have the option for 'doubling-up' using fold-down berths or futon-sofa furnishings. Such likely to happen if a small ship chooses to take on a paying passenger and shunts crew about for that contingency.
