3rdEd SJ Ship Size rules

These are the rules that I used to calculate the Size stat for
3rdEd SJ ship's hulls.  They are based on the standard 3rdEd
object size rules.

Using thse rules it will be possible to calculate a Size stat for
ship hulls for which just dimensions exist, and then use this to
help calculate the ship's AC.

The table can be reduced to a (given) formulae, which could be
used in ship conversion macro in Excel, or say a 'C' program.


Spelljamming Ship Size - 09/May/06

        Base     Limit    AC
Size   KL x BL  KL x BL   Mod
Large   10x  4   15x  6    -1
  1     20x  8   30x 12    -2
  2     40x 16   50x 20    -4

  3     60x 24   70x 28    -6
  4     80x 32   90x 36    -8
  5    100x 40  110x 44   -10

  6    120x 48  130x 52   -12
  7    140x 56  150x 60   -14
  8    160x 64  170x 68   -16

  9    180x 72  190x 76   -18
 10    200x 80  210x 84   -20
 12    240x 96  250x100   -24

 14    280x112  290x116   -28
 16    320x128  330x132   -32
 20    400x160  410x164   -40

 24    480x192  490x202   -48
 32    640x256  650x260   -64

Base, Limit: measured in feet
Size x 20 = KL, Size x 8 = BL, Size x 2 = AC Modifier
Keel Limit = Keel Base + 10, Beam Limit = Beam Base + 4
Note: Size 1 is Huge, 2+3 is Gargantuan, 4+ is Colossal

To convert a ship multiply together the KL and BL (after removing
any KL which corresponds to a ram) and find the closest Size, for
which the KL x BL is less than or equal to the Limit KL x BL, and
greater than the Limit for the previous Size.
