FT: % or Fixed Mass Screens etc?

Subject: FT: % or Fixed Mass Screens etc?
I was playing around with a spreadsheet for Full Thrust III (I know it
is not out until spring but I wanted to see how it would work) when
several points occurred to me:
1. There are fixed mass items such as weapons and others whose mass
is %
based such as drives. Are screens fixed or % based? If they are fixed
they let off big ships too lightly and if they are % based they might be
practical in small ships, and I would hate to see small ships with
screens.
2. I would like to see armour replacing screens. The same comments
apply
as for screens. 10% per armour level (if 1 to 3) or even 15% does not
seem too much to pay. See table II below.
3. The number of fire-cons a ship can be exploited in other ways
than
fire control. Make it the number of sensor rolls a ship can make
(already effectively the case in FT II). So small ships overloaded with
fire-cons and sensors make useful scouts (anyone for trawlers in
space?).
4. An expanded weapon selection. I like this. One type I would like
to
see are Spinal Mounts. Expanding the progression used by the A, B and C
batteries upwards should produce weapons so big that even a BB can only
have one firing in one arc only.
5. Now a really odd suggestion, why not invert the battery ratings,
so a
C becomes an A and an A becomes a C. This allows easier upward
expansion, so the AA Megabattery becomes a D (or maybe an E) and so on.
6. Is it unreasonable to give the AA Megabattery new range
increments of
12", the only reason for this is because it would be an easier fit on my
quick reference sheet (something like table I below) and it seems to be
a better 'fit' with the other batteries.
7. Streamlining should cost Mass, eg. semi-streamlining uses 10% of
a
ships mass and full 25%. Why? It seems reasonable and it would be useful
in campaign games.("Streamlining is for shuttles").
8. I assume that a ships uninteresting bits such as crew, life
support
and the like is included in the Mass of items, so a gun includes the
mount, the crew, the power supply and so on. SO are we going to see the
mass of everything doubling to allow for this? Probably not but it could
be a way of balancing some items such as screens.
Table I. Beam Batteries
Mass Damage at range:
FT2 FT3 12" 24" 36" 48" 60"
C 1 1 1d - - - -
B 2 2+1 2d 1d - - -
A 3 4+2 3d 2d 1d - -
--------------------------------------------------------------
D 4d 3d 2d 1d -
E 5d 4d 3d 2d 1d
F 6d 5d 4d 3d 2d
G 7d 6d 5d 4d 3d
H 8d 7d 6d 5d 4d
I assume that 60" is the maximum possible range due to limitations of
fire-control technology.
I think I would prefer lower damage at all ranges but some other
effect, such as improved penetration for the big guns.
Shotgunning does not seem very sensible if the targets are even
several
km apart let alone thousands of km, but it is very manga, still we have
the Nova Cannon for that.
Naval architecture was a fight between protection, speed and firepower
so I am very glad to see acceleration costing mass, with luck we might
be able to build proper battlecruisers!
Curiosity about how a ships mass was allocated led to a little research
(about 5 minutes) and produced the table below. Interesting is it not? I
would like to see more data but this will do to be going on with. It is
tabbed so I hope it works out when you receive it.
