How much is the scrap value of a well maintained starship?
How do you estimate depreciation and over what time scale?
TNE, you divide new price by wear value for base value. Wear value goes up a minimum of 1 per decade. Wear value is also the roll (1d10 ≤ WV) for a potential problem weekly per major system (LS, Hull, MD, JD, PP, Electronics/sensors, weapons), with a difficult (1d20<(Att+Skill)) to avoid an actual failure, performed by who did the most maintenance, and if the hours aren't met, it goes up temporarily.
Scrap can be inferred from CT (TTB 78) - typical repairs cost 2d6×10% of new cost; median repair is thus about 90% of new cost, of which, we're told 20% of new cost is labor and/or shop cost, thus 70% is
CIP
At 80% CIP, not done by crew, it's the same cost to replace with new as repair.
We can thus infer that scrap value is probably close to 20%.
That's not a canonical answer, but it's an inference from rules canon.
Was there ever a chart for chartering quotations?
Not that I recall, but a paragraph.
TTB 53.
I'll make it into a table for you...
Category | Ship | Small Craft |
Hull Tonnage | 0 | ×1 per hour |
Cargo Space | ×900/week | ---- |
Passenger Stateroom qualified for High Passage | ×9000/week | ---- |
Low Berth | ×900/week | ---- |
Fuel | all used for the charter | all used for the charter |
Salaries | whole crew | whole crew |
Fees | all incurred | all incurred |
life support and maintenance | all used | all used. |
I'll note that it lacks a bit of finesse... it doesn't include Mid Passage berths, nor any fittings of small craft, nor specialty equipment installed.
A CT Type T (TTB 66). Sans troops, it can't muster any HP, but has 12 SR. it has 50Td cargo, and 4 LB. So... chartering it for two weeks (a normal trip) is
160 Td Fuel | KCr80 | 160×KCr0.5 |
0×HP | KCr0 | 0×KCr9 |
50×Td | KCr45 | 50×KCr0.9 |
4×LB | KCr3.6 | 4×KCr0.9 |
Salaries PNEEEMGGG | KCr14.25 | (6+5+4.4+4+4+2+1.1+1+1)/2 |
Maintenance Share (1/12 AM) | KCr1.842 | KCr22.104/12 |
Ship's Boat | KCr10.08 | Cr1×30×24×14 (hourly, tons, hours/day, days) |
Two Weeks | Sum KCr 154.772 + berthing fees | |
Note that the payments are KCr921/mo, so it doesn't stand a chance as a commercial charter... even if you drop 2 gunnners and coöpt the remainder as a steward, too, that's +4×KCr9 and -KCr0.425 on salaries....
Still, it shows the process. I'll note that I don't use that rate.
I add KCr7 per MP qualified SR, and Cr300 per ton of hull per week (about Cr0.9 per ton per hour).
I don't have other editions to hand (am moving rooms).
Note that there are starmerc charter rules in MT's Hard Times (as well as a starmerc career).
