[Spaceships]Traveller Ships with economics

[thtraveller]

Inspired by the Economics thread here are my designs with basic economics calculated (using Far Trader economics as adjusted by G:Spaceships assumptions).

All ships are designed using David Pulver's JTAS article recommendation for creating Traveller ships with G:Spaceships. Principally this means one stardrive and fuel tank per jump number. Having already gone round the loop on this once I believe this is the best (or perhaps the least worst) option.

Ships in this thread are:

1000 ton (200 DT) Jump 1 Near Trader (Beowulf)
1000 ton (200 DT) Jump 2 Far Trader (Marava)
1000 ton (200 DT) Jump 3 Long Trader
300 ton (100 DT) Jump 2 Scout/Courier (Sulieman)
300 ton (100 DT) Jump 6 Express Boat
300 ton (100 DT) Interplanetary Shuttle
10,000 ton (2000 DT) Jump 4 Passenger Long Liner
10,000 ton (2000 DT) Jump 2 Freight Liner
300 ton (100 DT) Jump 4 Executive Yacht "Movable Feast"

1000 ton (200 DT) Jump 2 Far Trader (Marava)
1000 ton (200 DT) Jump 3 Long Trader (name?)

300 ton (100 DT) Jump 6 Express Boat
300 ton (100 DT) Interplanetary Shuttle
10,000 ton (2000 DT) Jump 4 Passenger Long Liner
10,000 ton (2000 DT) Jump 2 Freight Liner

1000 ton (200 DT) Jump 3 Long Trader (name?)
Likely the 400 ton Fat trader

[thtraveller]

Comparing the cost per passenger or cargo ton for a range of ships built to the same method as above gives:

Cargo ton per parsec
$730 J1 Cargo Liner
$710 J1+J1 Cargo Liner
$770 J2 Cargo Liner
$930 J2+J1 Cargo Liner
$1050 J3 Cargo Liner
$900 J2+J2 Cargo Liner
$1500 J4 Cargo Liner
$1100 J3+J2 Cargo Liner
$2900 J5 Cargo Liner
$1400 J3+J3 Cargo Liner

$900 J1 Beowulf
$930 J2 Marava
$1300 J3 Long Trader

Passenger Price* per parsec
$4400 J1 Passenger Liner
$4300 J1+J1 Passenger Liner
$4100 J2 Passenger Liner
$5000 J2+J1 Passenger Liner
$5300 J3 Passenger Liner
$4800 J2+J2 Passenger Liner
$7600 J4 Passenger Liner
$6200 J3+J2 Passenger Liner
$15000 J5 Passenger Liner
$6900 J3+J3 Passenger Liner
$34000 J6 Passenger Liner

$9000 J1 Beowulf
$9300 J2 Marava
$13000 J3 Long Trader

And this assumes the same utilization and stopover times for the Tramps as the liners.

Conclusions:
The Refinery needed by tramps to allow wilderness refuelling for adventuring purposes significantly reduces their profitability when competing in places where refined fuel is available.

Tramps need to charge at least 25% more than Liners for cargo, and probably at least 50% more as they will tend to have emptier holds.

Tramps need to charge at least double for passengers.

Cargo wont travel by anything above Jump-2 unless astrography dictates and will almost certainly travel on double hop liners on single jumps that are four or more parsecs.

Passengers probably wont travel above Jump-4 on liners and Jump-2 on tramps. They may take lower TL and cheaper double-jump liners on four or more parsec gaps.

*Passenger sharing a cabin. Luxury passengers and single occupancy passengers pay twice this. Low Passengers pay half this.

Economics are based on: 12% of ships cost repaid/year, depreciation 8%/year, $10K/month/crew member, Insurance 1.2%/year, 5% RoC, 90% utilization.

You realize that these are not even remotely like the canonical values? They're not wrong by any means -- probably more realistic, if the truth be told -- but then the results aren't comparable to what has been previously published for Traveller.

The mortgage and insurance are from G:Spaceships 2. Utilization is from Far Trader. Salary is a generalized figure off the Jobs table and has minimal impact anyway. I extrapolated depreciation based on mortgage period.

I would rather be more "realistic".
