Acquiring a contractAfter a few hours of trolling the tramp freight market, the best option is a package of 70 tons of valuable microbeads. Normally, the lot would go for about 273 KCr. However, the competition is intense. The ship's broker (Merchant-14) must apply -4 because this run follows a main trade route. The broker rolls a 8 vs Merchant-10, for a margin of +2. The contract is theirs for 287 KCr.
Three jumps will be required. Each jump requires 20T of hydrogen. Each ton of hydrogen when refuelled at a spaceport is 350Cr/T. So the H2 budget is 21 KCr. Seven weeks of food for 6 is about 2 KCr. Consumable: 23 Kcr
Salaries: 6 crew for 7 weeks would be about 63 KCr
Maintenance: 6 KCr
Mortgage: 400 KCr
Total: ~500 KCr
In order to break even, the ship must find another contract to fill the other half of the hold.
