OK this is for the gearheads. Here are the rules:
Rules Trade and speculation + local Cr derated by starport and tech level. T4 FF&S
Technology: Any class A or class B Imperial starport in the Spinward Marches or Trojan Reach sectors. Starport must have the ability to build your hull. If a class B, the jump drive must be imported paying 1000Cr/parsc/DT to ship it.
Hull : 100DT to 199DT only. May be of any configuration or streamlining or material available at the constructing starport. External cargo pod is allowed, these are bolted down (House rule) (explosive bolts allowed) no grappel required unless you intend to provide services like power or air to the external cargo. A flexible jump mesh is allowed, however the volume is limited by the DT of jump drive installed (DT drive/enclosed DT>=2%) You may install environmental gravity to a limited volume such as crew quarters only, crew, controls, and engineering only, all except fuel tankage. Attached cargo pods and drop tanks changes your configuration to dispersed. If you use grappels for cargo pods, an interesting thing is to put a small power plant and a minimal maneuver package aboard the pods to maneuver them to the high port (with coms and a remote control station).
Maneuver Drives: You are not required to mount 1G+ maneuver drives, however your transit times will be taken into account based on acceleration=loaded mass in mt/thrust in mt/10. Lighter services are available at A through C ports. High ports are available at all AS systems other than X and all A and B ports. Systems with red giant or simular sized primaries will have a highport at the 100D point of the star. Default Maneuver drive is the HePLAR if you are using a fusion power plant. Thruster plates and antigravity drives makes you detectible by gravetic sensors see erratta. Fusion rocket, ramscoop, and deadaelus drives require a non radioactive secondary thruster or a tug for entering and leaving dock, (most systems will require you to utilize lighters with a hazard bonus.)
Jump drives: Drop tanks require the jump drive to have been made at a TL 15 or higher system with a shipyard. Replacement tanks can be made at any A or B starport. The capacity of the tanks will vary as the material toughness is changed, plan for this when allocating your fuel tankage. Jump drive capacity may be designed to jump more than the ship's hull volume. The TL of the Jump drive sets the maximum J-N possible, the current displacement tons determines the maximum jump if the drive is capable of that jump number Example: TL 10 drive with 20DT in a 100DT hull could perform J-1 with 900DT of external cargos attached (1000 gross DT), still performs J-1 at 100 gross DT. A 7DT, TL 15 drive can J-6 in a 100DT hull(151.2MW, 60DT fuel) or J-1 at 350DT(88.2MW, 35DT fuel), J-2 at 233DT(117.4MW, 46.6 DT fuel), J-3 at 175DT(132.3MW, 52.5DT fuel), J4 at 140DT(141.1MW, 56DT fuel), and J5 at 116DT(146.2MW, 58DT fuel). The power must be provided continually till the jump bubble collaspes.
Power plants: Piezo Nuclear fusion (TNE FF&S1) (PNF), Fusion+ is allowed, Fusion is allowed, Fission is allowed, Antimater is not available in the area. Scale efficiency is not applied to PNF plants, and they do not have a minimum size. Scale efficency is not applied to Fusion+
Fuel: Jump fuel sufficent for 1 Jump-1 must be carried inside the base hull, as well as a minimum of 30 days of whatever fuel the power plant(s) use. Please review JTAS alerts for worlds that do not allow wilderness refuelling. Drop tanks can be obtained within 1 week at A and B highports for spherical configurations, other configurations available but may require previous contact and payment. Throw 2d6 - pop <4 for immediate availability -2 if you have jetisioned your "special" drop tanks here previously. Please note: Heavy water and duterium are not commonly available in Spinward Marches and Trojan Reach Imperial worlds in 1105, and are subject to contracted deliveries at A through C ports. (place fuel contracts while your ship is under construction)
Communications: Carry both laser and radio 1000AU range systems. One additional 500,000KM range radio is required for ships that are under mortgage.
Sensors: MK1 eyeballs are not good enough. Install something reasonable, your lender may have suguestions.
Controls: At least one workstation, a workstation or crewstation per each required crew.
Computers: Three are required. These are cheap in T4, and help you reduce your required crew.
Automation level: Spinward Marches/Trojan Reach in 1105 you make your choice.
Weapons: Required only if you are going to take on a mail contract.
Life support: Class 3 minimum. Coverage of volume of drives, acomodations, electronics, and weapons is required. Other internal spaces is optional. Airlocks must be installed to access these non life supported internal spaces.
Environmental gravity: You have to cover at a minimum, the accomodations space. Crew need to have gravity or suffer adverse health effects over time.
Budget: You have 12MCr(IMPCr) for any drives purchased elsewhere and shipped in and for your 20% down payment.
Loan Terms: 20% down 240 payments of 1/120 th of purchase price in LOCAL CREDITS of the building shipyard!!!!!
Discussion of the rules are welcome and rules may change as a result. I intend to do a second design challenge for Terra TL-9 era prior to contact with the Imperium.
Edit: left off the example J-6 fuel usage of 60DT.
