400 ton J-2 design

[sjmiller]

I imagine this is just me nit-picking, but I believe your spreadsheet rounds in such a way that while the totals might equal 400 tons in the background, on the sheet I can only count 399 tons.

I forgot to assign 1 ton for the ship's locker

Looks good. However, your TL 10 PP needs to be 16.25 tons per HG pg. 53.

We both made an error on our hull & structure points due to using < TL 12 hulls. (HG pg. 52)

I ignored it, assuming you was only considering using the first bit, just the 5% discount. If the rest was being used though, then both ships manoeuvre drives would also cost double but only have 75% of their stated normal tonnage.

 

[DickTurpin]

You don't get both the higher TL benefits and the discount for using older tech. If you want the latest improvments you are using a current TL product, not an old tech item manufactured using higher tech manufacturing methods.

Nope. You can buy a TL 15 drive (as you state) or, take a discount on a lower TL drive built at TL 15 world with same tonnage as the lower TL one. (see HG)

So following that, the hulls would remain the same by that logic if you get what I mean.

No, they are weaker (in our ships for example) because they use less robust materials...
