What transfers between sister ships, and what does not
32 charted classes. Each page shows what every hull shares and where they diverge — computed by comparing the ship records field by field, so a class rule cannot drift from the ships that carry it.
Only 4 of the 26 multi-ship classes are uniform. That is the case for reading one of these before quoting a sister ship from memory.

Classes appear here once a ship in them has been worked up. The eleven uncharted lines have classes too and none of them is listed, for the same reason none of their hulls has a page — the ships directory says which lines those are.
