Improved Thrust:  At the time of installation, a captain can decide to 
install an ion engine with more thrusting power and less speed, to increase
his ship's cargo capacity.  For every die of speed he take less than an 
engine's rating, add 20 tons of cargo capacity.  (This, of course, does not
increase the ship's hold's size, but it can carry heavier stuff in the hold.)

Lateral Thrusters:	Manuever Rating Increase
To increase a ship's manueverability by one pip (or from 0D to 1D), mulitply
the ship's hull rating (rounded down), times the die of maneuverability to be
achieved (rounded down), times 100 credits.  Each pip of increase must be 
purchased separately.  Cost: hull rating x dice of maneuverability desire x
100.  Note that thrusters have no appreciable weight.

Hull:
Improveing a ship's hull strength by armoring it makes it that much more 
difficult to damage.  It's also quite expensive indeed.  To increase a 
ship's hull by one pip, multiply the ship's hull rating to be achieved  
(rounded down) times 1000 credits.  Each pip of increase must be purchased
separately.  Cost:  hull rating desired x 1000.
	Note that increasing a ship's hull by one pip decreases the ship's
manueverability by one pip as well.  Treat any maneuverability of less than
1D as zero.
