Operational Costs for a Firefly

Postby Whitney » Sun Mar 30, 2014 2:43 pm

Here's a document I've modified a bit for use in our 'Verse:


Every individual ship has a monthly maintenance cost based on its age, size, traits, condition, etc. This is the gamut of things from basic part replacements, toilet paper, cleaning supplies, life support chemicals and filters, light bulbs, etc. etc. etc. For a Firefly like Serenity, the average monthly maintenance cost is 480 credits.

Spacehands have an average monthly salary of 50 to 100 credits. Monthly salary for officers, pilots, doctors, etc. is about double that. Captains generally take a percentage of the profits. Crew members could also be put on a percentage in lieu of a base salary. This often has the effect of giving everyone incentive to work harder.

Port Fees
Docking for the first week costs 5 credits for 100 tons of ship, then 2.5 credits for every week thereafter. This fee includes administrative costs, power hookup, septic flush, fresh water, etc. For Serenity, a 141.25 ton (282,500 lb) ton vessel, this fee comes out to $706.25/week (or $100.90 per day) credits for the first week, then $353.25 credits/week ($50.50/day) after that.

Standard liquid hydrogen fuel costs 25 credits per ton. This fuel is generally available on core Worlds or some Border Planets with well-developed economies. It is virtually never available on the Rim. A Firefly-class ship like Serenity has a fuel capacity of 60 tons. Using the reaction drive, fuel burns at a rate of 1 ton per ten hours (not including “full burns”*), so for a Firefly, the following table is used……[list]
[*] 60 tons= 600 hours= 1500 credits
[*] 10 tons= 100 hours= 250 credits
[*] 2 tons= 20 hours= 50 credits
[*] 1 ton= 10 hours= 25 credits
[*] 200 pounds=1 hour=2.5 credits
Remember that the ship must engage the pulse drive once at the beginning of any voyage between planetary bodies. Engaging the pulse drive burns 10 tons / 100 hours / 50 credits of fuel.

A “full burn” (also known as a hard burn) occurs when the ship engages its pulse drive, providing a burst of speed, often useful for making up lost time or eluding pursuit. A full burn uses up 100 hours of fuel, plus 50% more fuel for the time it is engaged.

Food comes in a lot of varieties in the ‘Verse. Luxury Foods like a pound of fresh strawberries or a chocolate ice cream cake are rarely if ever found on working ships like Serenity. Even Fresh Foods like fresh vegetables, fruits or meats are rare because they are expensive, hard to find and require refrigeration. The most common foods on a working ship like Serenity are Canned Foods like potted meat, peas, corn, etc., and Protein Packs, which are tubes of colored and (supposedly flavorsome) protein paste. Protein packs are the standard fare for most space-goers in the black. The paste is sometimes molded into different forms and cooked in different ways, but usually tastes about like protein paste. Healthy but not especially tasty. Feeding one person for one week (3 standard meals per day) costs 35 credits for canned foods, and 17.5 credits for protein packs. A crew of 7 could eat canned goods for 245 credits per week, or protein packs for 122.5 credits per week. Ships liable to take on paying passengers should keep extra food supplies around.
