Regarding airlocks,
Spaceships, p. 42 says:
The capacity of an airlock is the maximum number of human-sized individuals that can occupy it. The table below shows airlock capacity and area (in hexes) by spacecraft SM:
Code:
SM +4 +5 +6 +7 +8 +9 +10 +11 +12 +13 +14 +15
Capacity * 1 1 1 2 3 4 5 6 7 8 9
Hexes * 1 1 1 1 1 1 2 2 2 2 4
*The ship is too small for airlocks or, to put it another way, the
entire ship is an airlock.
But
Spaceships, p. 10 says:
Along with their 20 systems, all spacecraft get the following equipment.
Airlocks for entering the vessel. A spacecraft can be assumed to have (SM-4) airlocks, with each airlock capable of admitting (SM-4) persons per cycle.
Which means the Capacity line should look like:
Code:
SM +4 +5 +6 +7 +8 +9 +10 +11 +12 +13 +14 +15
Capacity * 1 2 3 4 5 6 7 8 9 10 11
