Copyright (c) 1993 Onno Meyer Another one for the Net.Vehicles.Book: GURPS Vehicles TL5 torpedoboat This is the adaption of a german torpedo boat from 1887, but I had only displacement, engine power, speed, length, crew and the picture of a boat from that generation. The remainder is "made up". The lack of a superstructure is intentional - the picture showed none. I assumed coal to be 0.015 cf/lbs. My simulation is faster than the original, either because I under- estimated the armor or because my source (a very old lexicon) lied about the data on then modern warships. Structure: 4,500 cf medium standard body; flotation hull; mediocre lines (flotation 90 t); 300 sf top deck. Propulsion: 750 KW screw. Power: 750 KW triple-expansion engine consuming 1,125 lbs. coal per hour. 54,000 lbs coal give 2d endurance with 1152 miles range. Accomodation: Seven cramped quarters (for 13 crew in two shifts). Accessoires: Bilge pump, navigation instruments, provisions (1 month* 15), workshop. Weaponry: Two fixed torpedo tubes (front) and one tube in an open mount (back). Eight torpedos. Armor: 30 pts. F6 B4 R5 L5 T6 U4. Cargo: 100 cf (and 166 cf access space). Statistics: Cost $350,700 (adjusted for inflation to $17,535), design mass 167,190 lbs., max payload = current load 12,810 lbs., max cargo 2t, loaded mass 90 t, size +6, radar +6, IR +8, acoustic +4. Performance: Speed factor 12 mph, top speed 24 mph, accel 1 mph/s, decel 11 mph/s, MR 0.5, SR 6, draft 9 feet.

I corrected one little mistake. This is the adaption of a german torpedo boat from 1887, but I had only displacement, engine power, speed, length, crew and the picture of a boat from that generation. The remainder is "made up". The lack of a superstructure and a gun is intentional - the picture showed none. Yet another similar craft had one Seeoffizier (naval officer), one Maschinisten (mechanic), two Bootsmannsmaaten (boatswains mates), three Maschinistenmaaten (mechanics mates), four Matrosen (able seamen) and four Heizer (stokers) - cancel probably one stoker to get to the 14 on this design. My source was the Brockhaus' Konversations-Lexikon, 14th ed., 1896. I assumed coal to be 0.015 cf/lbs. Structure: 4,500 cf heavy advanced body; flotation hull; mediocre lines (flotation 101.25 t); 300 sf top deck. Propulsion: 750 KW screw.
