Reference Formulas for
Creating Ship Stats
SCALES & SIZES:
Ship size = Full displacement
divided by 422. Values of larger vessels are
rounded, usually to nearest 5.
Speed = Small scale (MM): original speed multiplied by 6.12,
Medium scale
= original speed multiplied by ???
ARMOR THICKNESS
RATIOS:
Nickle Steel 1.00
Steel 0.90
Compound 0.70
Wrought Iron
0.50
VESSEL ARMOR VALUES (in inches):
Definitions:
BLT
= Thickest main (waterline) belt value
uBLT = Thickest value of upper belt
SLP = Average thickness of sloping armored deck
MAIN = Averaged
Thickest Turret/Gun Shield and Barbette
ROOF = Thickness of turret roof
SEC = Average thickest secondary turret or casemate
DCK = Total average
of all horizontal (deck) armor
BLK = Bulkhead thickness
A =
Broadside value at close range
B = Broadside value at medium range, end-on
value at short range
C = End-on value at medium range, both angles at long
range
Capital Ship with Belt Armor:
A [BLT + (SLPx1.5) x
.45] + [MAIN x .40] + [SEC x .15]
B [uBLT + (DCKx1.5) x .45] + [MAIN x
.40] + [SEC x .15]
C [DCK x .9] + [Averaged MAIN & ROOF x .3]
Belted Armored Cruiser w/o Barbettes
A [BLT + (SLPx1.5)
x .40] + [MAIN* x .30] + [SEC x .10]
B [uBLT + (DCKx1.5) x .40] + [MAIN
x .30] + [SEC x .10]
C [DCK x .8] + [Averaged BLK and MAIN x .40]
C
[DCK x 1.3] + [MAIN x .15]
* - May include averaged bulkhead value
Armored Cruiser w/o Barbettes or Belt
A [(SLPx1.5) x
.60] + [MAIN x .20] + [SEC x .10]
B [DCK x 1.3] + [MAIN x .15]
C [DCK x .65]

SHELL SIZES
Actual shell size = weight in pounds divided
by 23. Values of larger guns are then rounded to nearest 5 or 10 to speed game
play. Most shell sizes under 15 use actual value without rounding. Gun
penetration equals average penetration of nickle-steel at 3000, 9000 and 14000
meters range. Gun Velocity is average for 2500-2700 fps, low for anything
under, and high for anything over. UK = United Kingdon, DE = Germany
(Deutschland), US = United States (currently for reference), JP = Japan
(Currently for reference).
