[gurps] [VEHICLE] of the week 714 -- Gashidda-class 400-ton Surface Defense Boat

[Thomas Thrien]

You wrote: "[...] The Gashidda-class 400-ton SDB was designed to penetrate the armor of Imperial grav tanks [...]" and "[...] The funnels of the twin steam engines restrict the turret rotation to 330° unless the cannon is raised for anti-air fire. [...]". And the vessel is TL5.

All this says to me that the cannon is usually not used for indirect fire: for a TL5 artillery firing on moving targets was fruitless as they could not perform the required calculations fast enough and then load the gun in time - not to forget that they were not capable to determine both positions (that of the gun and that of the target) accurately enough.

That brings me to your design: even if the boat knows where it is, what about the forward observer? How will he determine his position? Also with 2 times 3 sets of navigation instruments?

I still doubt that such a vessel would have (or need) this additional three sets of navigation instruments in the turret.
