Starship computers are if anything too small...
That's a hoot! ...but a discussion for another thread.
At a minimum, I'd point out that CT requires 20dT for a bridge, but then you don't install the several-dT-sized computer in the allotted bridge space. No, it is additional space taken out of the ship. And what, exactly, is in that 20dT bridge?
This will surprise no one, but Mike neatly summed up my view on Straybow's post.
The fact is the ship design was built to get on with the business of getting PCs into play as adventurers, not modeling the engineering concerns of an interstellar shipyard. The rules do the job for the job intended.
As Mike points out, if one wants to pursue a more refined approach for designing ships the methods are there. But they are not required for a countless evening's worth of RPG play that Classic Traveller was designed to provide.
Again, I'm not talking about reinventing Traveller.
The ship design rules get in the way rather than speeding the process. A ways back in the thread there was a question about the difference between "standard hull" and "standard design."
Why, why in all the galaxy, is the hull of the standard design not a standard hull? Why would a standard hull be set so that any reasonable configuration of power and drives leaves wasted engineering space? Then the rules say you can't use engineering space for cargo, or even to store ship's equipment (A/R, for example). Nope, it can't be partitioned off in any way.
It's like the standard hull was produced according to one government bureau, and the standard design by another, divided by an insurmountable mountain of red tape. Nobody, in all the centuries of spacefaring, in all the naval architect firms, in all the shipyards, and even on the throne of the empire (or office of the president, or whatever) has ever said, "Fix that."
This is what I mean by "canon." The rules don't say, "There would be standard hull configurations and standard ship designs available for discount." That would leave details of those hulls and designs to the setting. No, the rules chisel the standard hulls and standard designs in stone, and you guys are busy repointing the mortar.
If you really want Setting Independent Proto-Traveller, then discard the setting wherever it appears. But the dividing line is fuzzy. Hulls exist in 100 ton increments (and 10 ton increments below 100, except for the shuttle that is 95 tons). Power plants and drives only come in 24 sizes. That is stated as if setting-independent, but implies a setting-dependent standardization.
In particular this point:
- There is a certain elegance to the tables in LBB2 for quickly designing ships.
Not really. In play it doesn't matter what your drive letter is, only your jump or maneuver performance. The letter is useless information once the design is complete.
At the bottom of the drive size table is a note. "MCr per ton: 1.0 [under Jump Drive] 2.0 [under Maneuver drive] 1.0 [under Power Plant]" Would it be more elegant to create columns with the cost already calculated, or is a simple formula what is actually elegant?
Maneuver Drive = Hull·(G+a)·b @ MCr1/dT
Jump Drive = Hull·(J+c)·d @ MCr2/dT
PP = Hull·e+(G+a)·f+(J+c)·g @ MCr1/dT
I need only 7 factors for the whole shebang (or 5 if e=f=g). If you want to say that standard engines are rounded up to whole numbers, or increments of 0.25, or 2.5, or whatever, that's implied setting.
