1st edition HG Capital Ship Design Example p. 69 Step 1 Hull TL-15 material cost

[snrdg121408]

Hello all,

1st edition HG Capital Ship Design Example p. 69 Step 1 Hull:

Reviewing the options available from the capital ship design section, the expanded spacecraft design section and the core rule book, Julia decides to make the hull from TL15 materials. This increases the cost by MCr4,125, but increases both hull and structure points from 1,500 to 2,143.

Looking at the text I was able to determine that the hull and structure points was determined using the table below the Hulls Low/High Technology Hulls on p. 52.

Unfortunately, I have not found how to calculate the TL 15 material cost.

Can anyone please help me with calculations?

Does the 2nd edition HG do a better job at of explaining how low and high technology hulls work?

Top of page 62 (in my 2nd printing copy) says how much hulls cost.

 

[AnotherDilbert]

For her heavy cruiser, Julia chooses a CP Hull (75,000 tons) and a cone configuration, giving a hull cost of MCr 8,250. ... Julia decides to make the hull from TL15 materials. This increases the cost by MCr 4,125, but increases both hull and structure points from 1,500 to 2,143.

The table on p52 says the cost is 150% with TL15 hull material. Reasonably we can assume that it is the hull cost that is multiplied with 150%, which equals 50% of cost added, just as the design example shows.

Remember that High Technology Hulls are a Spacecraft Option (as it is in the Spacecraft Options chapter) and can be added to any of the different design systems in the 1st edition.


2nd edition has a different system where hulls can be slightly weaker and cheaper, standard, or slightly stronger and more expensive, regardless of TL.

Morning (PST) ShawnDriscoll and AnotherDilbert,

Thank you both for the replies to my question.

My apologies to you ShawnDriscoll for not being clear on what I was asking concerning the TL 15 material which is what AnotherDilbert describes is the application of the Primitive and Advanced Spacecraft Low and High Technology Hulls rule from 1st ed. HG p. 52.

I was on the fringes of your explanation AnotherDilbert, which helped nudge me in figuring out how the example applied the rule. There where two things that tripped me up, the first was that the Low/High Tech Hull modifiers are applied to the Hull cost + Configuration cost and the second was using 0.5 versus 1.5 when calculating.

The 2nd ed. HG hull technology appears to be similar to GURPS Traveller Starships. I really wished I had been paying attention when the 2nd ed. CRB/HG beta copies had been available. But, I was snoozing and I'm paying for the nap I took.

Again thank you both for your help. Stay tuned for my next silly question concerning 1st ed. MgT Spacecraft Design, Spacecraft Options, Small Craft Design, and Capital Ship design.
