I always wondered what I could tow with a Cobol and not run out of fuel, or how much fuel I’d have to put on my Cobol, based on what I was towing and how far I wanted to get. Here are the answers for some common situations.
Assumptions: All ships full of cargo (except Virgo = 125 fighters only). Cobol starts with full fuel. Towed ship starts with 1 fuel except where noted (f):
| Ships | Mass | 81 ly | 162 ly | 243 ly |
|---|---|---|---|---|
| Empty Cobol | 123 | 152 | 305 | 457 |
| Full Cobol (50) | 459 | 125 | 249 | 374 |
| Full Cobol (450) | 859 | 92 | 185 | 277 |
| Cobol(50) + Gemini | 1004 | 81 | 162 | 243 |
| Cobol + Gemini | 1404 | 49 | 97 | 146 |
| Cobol + Virgo | 1615 | 31 | 62 | 92 |
| Cobol(50)+Virgo(400) | 1615 | 31 | 62 | 92 |
| Cobol + Gemini (f) | 1754 | 20 | 40 | 61 |
| Cobol(50) + LDSF | 1790 | 17 | 34 | 51 |
| Cobol(250) + LDSF | 1990 | 1 | 2 | 2 |
| Cobol(450) + LDSF | 2190 | -15 | -31 | -46 |
| Cobol + LDSF (f) | 2790 | -64 | -128 | -192 |
| Cobol + Virgo (f) | 3165 | -95 | -190 | -284 |
| Cobol + STF | 3620 | -131 | -262 | -394 |
(f) = towed ship is full of fuel
Conclusions:
A Cobol can tow a total mass (including itself) of 2000 kt an infinite distance. This means:
- If towing a Virgo, don’t put more than 525 in [fuel + fighters + cargo] on the Virgo, and you can tow it forever.
- If towing a LDSF w/1200 cargo with a Cobol (w/ 260 cargo), only add a maximum of 250 fuel between both ships.
- The Cobol will gain fuel when towing a Gemini, even if both ships are full (of fuel and cargo)
- You can tow a cargo-laden Super Transport Freighter (STF) with a full Cobol, and escort it with a near-empty Cobol (50 fuel only), and if you keep transferring fuel from the empty Cobol, you’ll never run dry.
