Evening arakish,
Could you please cite the source that was used to conclude that a double hull has double the hit points?
This is a house rule. I looked it up, and it is actually not a doubling of hits. It is a doubling of the HATs reduction of critical hull penetrations. Sorry for the confusion. I knew it was a double something.
Haven't done much ship construction since we use the standard ship types we already constructed.
Hello arakish,
Answering MarkC's reply my brain finally noted that in the reply to Defendi on superior alloys the material code was CAT XXX.
SM: P CAT material codes go from XI to XX, while SM2 codes are the CAT 21 (XXI) to CAT 30 (XXX).
Is the CAT XXX really CAT XX?
Unfortunately, I still haven't found any mention of doubling hit points for a double hull of the best CAT material in either SM: P or SM: 2.
I also seem to have a different idea of double hull construction and hit points.
To me a double hull is a modified single hull that splits the designs total mass between outer and inner plating.
Here is my understanding of hit points per SM: P VM p.100. a design's base hit points is equal to the mass of the construct regardless of the CAT Material code used. A 100-ton construct using a single, reinforced, or double hull CAT has a base hit points of 100. To increase the hit points you need to add an armor belt, which also increases the DB per SM: P VM p. 99. The maximum DB and hit points the 100-ton design can have is +25 DB and an additional 25 hit points for a total of 125 hit points regardless of CAT type.
In the reply to Defendi
We have always allowed persons to apply a double hull, even HAT XXX can be doubled up if the person is willing to spend for the mass and volume. We just rule that this will double the ship's hits. But this is usually only done for the true battlewagons such as Monitor Battleships, etc, since their maneuverability simply makes them sitting targets. Thus, they need the extra armoring to withstand the extra attention.
I'm getting the impression from the above quote that a double hull is two complete hulls joined together which would double the hit points by doubling the mass of the design. Of course I'm probably totally lost in space in my understanding. ;-)

First, I need to point out that although our VCG (vehicle construction guidelines) system is very similar to those in the SMPVM, it is slightly different. Our system incorporates CAF (construction armor framing) and HAT (hull armor type). The CAF is the ship's framework on which everything else is built. The HAT is the protective "skin" of the ship. Both of these systems are purchased separately in respect to mass and volume. However, both are required to even have a ship. Can't have a ship without a hull. Can't have a hull without a framework to build it on.
Also, I have no idea what CAT stands for in the new SMP system. Unless it is the same as in the original SM system: Construction Armor Type.
In our system, HATs run from XXI to XXXV, or if arabic numerals are preferred, 21 to 35. We decided on this so as to differentiate ship armors from personnel armors. Although one could say "CAT 18", we sometimes just say the number. Thus, 28 cannot be confused with 18 as in the current SMP system (18 could mean CAT 18 or AT 18).
In our system, we have no Superior Alloying, since such techniques are automatically incorporated into the HATs as additional cost factors which allows one to apply a DB, additional hits, and critical hull penetration reduction (CHPR). In other words, if you want just one, you can apply only a DB, only additional hits, or only CHPR. But if you want all three and have the money, you can purchase them. Also, we call this Superior Construction Techniques instead of Superior Alloying.
Also, we do not have such things as CAT XVIII = doubled up CAT XIV. However, there are some "reinforced" versions. In other words, each HAT is a single hull. And each HAT, if mass and volume are paid for, can be doubled, tripled, etc. However, even TIWs rarely more than double their hulls, and usually only with the big boys (heavy cruisers, dreadnoughts, battleships, etc.).
Thus, I apologize for any confusion.
Sorry.
Furthermore, I will pull the HAT table data out and post it here in a separate topic. That way everyone can use it, trash it, or offer addtional ideas.
