Drive potential table - filling in the missing hulls

[mike wightman]

I don't like the rule that says a 300t should use the drive performance of a 400t hull, especially since it is so easy to interpolate from the drive potential table.

Here's what I mean:

I read it this way:

200 units sends a 100-ton hull Jump-2 so you need 100 units per 100 tons of hull to go one parsec in one jump. And I round all fractions down.

My table isn't that different, though. And I agree with your ratings for the 500 and 700-ton hulls.

 

[mike wightman]

Oops, thanks Oz.

I made a mistake copying the 300 entry from the paper version

That's pretty much how I did it as well.

As you say, things get interesting at W and above.

The W drive appears to be in the range 4000 to 5000 (why isn't the 800t hull given a peformance of 6 with this drive otherwise?), the X drive ranges from 4800 to 6000, the Y drive has a range of 5500 to 8000 (any more than 5500 and it would be too powerful for the 800t hull), and the Z drive from 5500 to 12000.

It looks like the W - Z drives can be "tuned" to the size of hull.

I'm going to post the 1000 to 2000t hulls next, in 100t increments.

 

[robject]

Oz is right, if you use the standard drives, of course.

 

[The Oz]

I give the last four LBB2 drives these potentials:

W-drive = 5000 units
X-drive = 6000 units
Y-drive = 8000 units
Z-drive = 12000 units

These are the minimums needed to get the published performances. It does lead to the error Sigg has pointed out: the W-drive should give an 800-ton hull a rating of 6, not 5 as shown in the LBB2 table. I have changed this IMTU, and I think it'd be a good change for PT.

I don't think a table for every 100 dtons is needed, Sigg. Just divide the drive potential by the hull displacement and drop all fractions; that gives you the rating of that drive in that hull, with a maximum allowed rating of 6.

 

[mike wightman]

Using those numbers, which I agree with, the X-Z drives should be too powerful for an 800t hull, while the Y and Z drives are too powerful for a 1000t hull - unless they can be tuned down as I suggested.

And I agree with your method Oz, dividing the numerical "unit" potential by hull size and rounding down, but some people prefer a table to look things up and to see patterns

How are you defining "too powerful?" I've never really thought about that.

I agree that larger drives can be "tuned down" to still be used in smaller hulls, though. It was actually used once that I know of, in the IISS Ship Files from GW.

And I agree with your method Oz, dividing the numerical "unit" potential by hull size and rounding down, but some people prefer a table to look things up and to see patterns

Some people are afraid of math, too....

Hmmm, I've never noticed that myself. Have to make another change to the drive table, methinks. Luckily it's only one spot on the table.

And I think it's time for a full review of the drive potential table. A quick look shows no other discrepancies. What do you think, Sigg?

If you divide drive potential "units" by hull size, round down, and the resultant number is greater than 7 then the drive is too powerful for the hull - otherwise why are hulls 600t- forbidden from using larger maneuver drives and power plants?

I'll have to go re-read it.

Yep.

If the drive potential "units" method was used it would free up quite a bit of space in the book...

I think a full review is an excellent idea.

Looks good, Sigg.

I'll steal that and change the 800 and 1900/2000 ton hulls as needed.

Thanks for the work.

How many additional drives do we need to extend the 5000-ton hull to jump 6? 20 more?

Looks like some of them would be interleaved with the standard drives, too. Messy.

The real problem there is the implication in Book 2 that drives beyond Z are above TL15. HG is a totally different design theory in this regard and the two are completely incompatible and the idea that they can be freely mixed in designs makes no sense at all. To borrow some letters, YMMV
