I'm trying to get my head around BB2 ship construction.
For a 800 ton hull why would one use a Drive G and not a Drive D?

Damage soak mostly.* In an 800ton hull:
A Jump Drive G can take 3 hits in combat and still perform a jump. A Jump Drive D is unusable after just one hit in combat. You can't jump without repairs.
A Maneuver Drive G can take 3 hits in combat and still perform at 1G. A Maneuver Drive D is unusable after just one hit in combat. You're a sitting duck until repairs are made, or worse a crashing one if your previous course was towards a gravity well.
A Powerplant G can take 3 hits in combat and still perform at 1P. And it uses the same amount of fuel as the Powerplant D. The Powerplant D is unusable after just one hit in combat. You can't do anything (including powering other drives, or full life support) until repairs are made. Batteries provide some limited life support for a few days. Additionally a Power Plant G with a Maneuver Drive F or less will allow you to double your energy weapons fire effectively doubling your combat hardpoints if you go all energy weapons, without doubling the cost or manpower. You do need a big enough computer to run the Double Fire program, and there is a small chance for damage to the Powerplant, but it's a huge advantage for a military ship.
* Think of it as backup systems. Mostly useful for military ships. I have a house rule that extends the usefulness to cover civilian ships that use unrefined fuel or skimp on Engineers and suffer drive failure. Under the "Drive Failure" rules (pg 6) rather than the drive in question quits working I handle it like a combat hit. So the letter code is dropped by one. Having a bigger than needed drive allows you to still operate even with a drive malfunction event.
* I've always liked, and often used, this part of the rules. It's something High Guard for some reason dropped.

Ah, ship combat. I haven't got to that yet
Thanks, for your excellent explanations.

You're welcome
Don't hesitate with any question, some of it (like this one) hinges on other areas of the rules to make sense (and sometimes not even then
).

Ordinarily, you wouldn't use a Drive G, since it doesn't offer any improvement in performance. However, a G drive would be much more resistant to damage--it can take 4 hits before being knocked out vs 1 hit from the D drive. You might also salvage a G drive (or get one real cheap), so that could explain how a G drive might wind up in an 800 ton starship.
That makes good sense. I'm surprised it wasn't part of the original rules !

Hey Robject, what's the official extension you mention?
I dunno if this is the official one, but here is one: http://www.travellerrpg.com/CotI/Discuss/showthread.php?t=10770
I went through and did a little bit of tables clean-up... but it needs a lot more work.

That was an issue open to resolution waaay back when the server was reset and Hunter was around a bit. Last spring maybe? I think it needs Hunter to do it. There was a thread in the "CotI Website Issues" I think, if you can find it and post there Hunter might see it on one of his passes and fix it up.
EDIT: heh
Searching, searching, searching... and I loathe the new search (mal)function....then I see it, stickied right there at the top of the page
Oh, and yes, only an Admin can fix it, and that's only Hunter at the moment.

I agree with the battle damage, but would add one thing: deck cargo. Now I believe that officially in canon, if it was 810 tons, you had to treat it as 1000 (he says with the vagueness of someone believing his LBB's to have been moved roughly 1600 km, and knowing them to not be unpacked), but if a over-spec drive was mounted, then I always allowed some wiggle room on 30 or 60 dtons' deck cargo's not dropping performance.

Yep, you recall correctly samuelvss.
Any tonnage over the table amount is treated as the next hull size for drive performance. So an 800ton hull with a G (or E or F) drive could add 200tons without suffering. But an 800ton hull with a D drive would have no capacity for any extra tonnage.
Good addition to the possible reasons

Ah yes, robject... why wait to introduce the Dark Side into the discussion when you can start recruiting at the earliest opportunity?
