This is a weekly posting with GURPS vehicles (and the like) to the 
GURPSnet mailing list. I grant the permission for all non-commercial 
redistribution of my work, but I would like to know if you put it on 
a website or the like. The files at omeyer.gmxhome.de are down until 
I fix the automatic PDF generation, which should be one of these 
days - see sourceforge.net/projects/gurpsml

Submersible Steam Torpedo Ram v1.0 (TL5)
  Copyright 2013 by Onno Meyer

  Her Majesty's steam rams protect the ports to safeguard the essential 
trade and commerce of the Empire. Beneath the waves, they are safe from 
storms and shellfire alike, and free to strike terror into the heart of 
any invader who dares to cross the Channel.
  On the surface, the ram reminds many observers of a swordfish. She has 
a sharp steel prow, and two hatches for locomotive torpedoes are mounted 
where the eyes would be. Two lower tubes are hidden under the water. The 
funnel stands in place of the dorsal fin.
  Inside, most visitors are dismayed by the constant din and the smell. 
A maze of pipes and valves covers every bulkhead. The bow contains the 
torpedo room, where the seamen live. The captain and the officers have 
individual cabins near the pilot house, and the stern is filled by the 
steam engine, the boiler rooms, the batteries, the electric motor, and 
the coal bunkers.
  The batteries last for 92 nautical miles at 3.9 knots, or 16 miles at 
the top speed of 12 knots. On the surface, the steam engine burns 5 tons 
of coal per hour at routine speed. A full load of torpedoes, fuel, and 
provisions is $146,800.
