IISS Ship Files enigma

[Black Vulmea]

Both Adventure 4 and IISS ship files were written/designed by Bob McWilliams.

The plans are drawn by Albie Fiore. I love his work.

So why not build a ship to its specifications

Trouble is working them out

1. It has at least three decks, based on hatches and lifts.
2. Excluding the displacement of the drives, the deck plan shown is roughly 181 dtons; the upper and lower decks could be the same, or smaller.
3. There are three bridge stations, suggesting a pilot, a navigator, and possibly one gunner.
4. The computer is 2-3 dtons.
5, No fuel tankage is shown, unless that's the "no floor" area to port.
