SOC-13
Ok sports fans Presenting the saturn

J-6 100 Dt 1g crew 2 TL 15 with grapple for a 35 Dt drop tank. The ship has no provision for internal jump fuel, no passengers, provision for 81
Dt of cargo
Maneuver drive is HEPLAR with 27.6 Gturns (half hr) of fuel. 4 large cargo hatches and some automated cargo handling equipment (one for standard modules, one for non modularized pallets) give an unassisted unloading rate of 5 Dt/hr (7dt/hr with additional equipment) total cargo cycle is 34 hours unassisted 22 hours with assistance/extra equipment.

HULL:
The ship's hull is a standard sphere with the minimal 20 armour coherent ultradense stressed to 4.7g's. There is no provision for streamlining or fuel scoops, fuel purifier, or antigravity drives. The hull does not have provision for landing gear.

Ahh but that's not the whole story.

The Rings:
250dt .001g, system ship
mounting a full grapple for a 100Dt sphere, a small power plant, 2 flight computers class II environmental controlls and 1G comp, a very small HEPLAR drive sends it at .009 g's loaded, .1g empty, oh yes and 236 Dt of cargo, 10 large hatches with full containerized handling system 40Dt/Hr full cargo cycle in 22 hours.

HULL:
Thin Disk 1:10 with a 13.9 meter hole in the center where the Saturn is docked. Hull is armour factor 20 stressed for .25g's made of the same materials as Saturn. The Rings has no provision for landing gear, streamlining fuel scoops, antigravity, or fuel purification.

Notes: The Rings is radio controlled my either Saturn or local starport control. She does not mount any sensors, and there are no workstations for local control.

INCOME:
CR 472,000

Performance when Saturn is docked in The Rings:
J-1 .3G's 317dt cargo (drop tank 35Dt supports 1 J-1)

COSTS

CR 228,734 + 5918 = 234,652

INCOME

CR 162,000 + 472,000 = 634,000

NET

634000 -234652 =399,348

The ship can ply a high volume J-1 route between two high population worlds, then J-6 to reach it's annual maintance location then return and take up the route again with just 4 weeks off route a year.

Return on investment a nomial 4 MCr per year not counting the 40 year payoff rate. Approxi a 12% per year ROR.

Who says you can't make money with a J-6 ship. This ship can get over the gaps between mains, and skip over the dangerous or unprofitable worlds along a main
