The RAW requires a power plant to be at least equal to the largest drive installed. A TL 13 Power Plant 4 requires 2% x Pn of the hulls total volume. 100 x 0.02 x 4 = 2 x 4 = 8 tons. The power plant's fuel is 1 ton per Energy Point. Energy Points = 0.01 x 100 x 4 = 1 x 4 = 4 tons
Hello Tom,
As a book 2 design it requires power plant B at 7 tons plus fuel at 10Pn = 40 tons, which is why they couldn’t fit a power plant and thus no manoeuvre drive.
I’m not sure why they didn’t include a Model 4 computer, since those don’t seem to need power in book 2.
In CT LBB 2 1977 the computer model number did not indicate the highest level of jump that can be achieved by the ship. The criteria is that the computer CPU number had to be able to run the software size. A J4 program requires 2 CPU spaces to run. A Model 1/bis has a CPU rating of 4 and requires 1 ton of space. A Model 4 computer requires 4 tons.
Using book 5 you have room for a stateroom (4T) cargo (1T), Model 4 (4T + 2EP => 2T fuel + 4T PP) + Jump 4 (5T drive + 40T fuel + 8T PP + 4T PP fuel) + bridge (20T).
That leaves 8T which would allow a 3G drive.
Looks like I should have used a spreadsheet instead of punching in numbers on my calculator and then writing the numbers down. Unfortunately, when I ran the numbers using a spreadsheet my tally does not match the calculations above.
TL 13 Jump Drive 4 (5T) + TL 13 Power Plant (8T) + Jump Fuel (40T) + Power Plant Fuel (4T)** + Bridge (20T) + TL 10 Computer Model 4 (4T) + 1 x Staterooms (4T) + Cargo (1T) = 86T
The unused volume is 100T - 86T = 14T
Adding a TL 8 Maneuver Drive 3-G (8T) leaving 6T which would allow reinstalling the second stateroom and increasing the cargo capacity to 3T.
Adding a TL 8 Maneuver Drive 4-G (11T) leaving 3T which would allow increasing the cargo capacity to 4T or reinstalling the second stateroom.
**HG 2e p. 27 Power plant fuel computed a 1% of ship tonnage per power plant number (0.01 x 100 x 4 = 1 x 4 = 4T). One ton of fuel supports one energy point of power plant output) which gives the power plant an output of 4 EP.
