Default Deck Gun Sight

Firing at the enemy and sight was spot on; eg: straight. Next ship and sight has 'moved' to the left so I have to compensate by firing off left to hit target. Its off to the left more than correct. Do we have a mod that ensures sight is correctly aligned?

Not that I'm aware of, but I've noticed that with distance, and I always put it to "windage", though I'm sure they never intended to model that - did they?... surface pitch from sea conditions is another good excuse... don't wanna call it "bad training", 'cause then it reflects on the skipper...

Does this happen on more than one patrol? I ran into that issue once with the 5" gun; only once we approached home port did the crew announce that the deck gun had been fixed. Apparently it, and it alone, took some mystery damage sometime after the first gun engagement.


It's interesting watching the 5" shells curve in flight sometimes.

You can "tighten-up" the aiming of the AI deck gun crew in the cfg files, but I'm not sure about the "look" of the aim... It somewhat varies by the speed of your boat, and the speed of the target boat, along with the heading of both, as well as angle-on-bow involved, and the distance the shot has to travel. ie:, if they're going west, and you're going east, more "lead" (with a long "EE" sound - and "lead" with a short "EH" sound) is needed when they're perspectively moving faster. So, coming straight on from a distance, you might not have to "lead" them so much, but if they turn away as they get closer, you might have to lead them more to keep up with their forward movement, against your forward movement. You'd be somewhat "side-arming" the shot, like a pitcher in baseball might, or a US football quarterback might, going across his body with the receiver going the opposite direction... I am awful at concise explanations... sorry 'bout that. But it does "look" like the game tried to "model" that phenomenon, but it might be inconsistent... ??

this can happen even if stationary. It happens all the time, in all scenarios and all weathers and all the war. More often than not it is out. I would say 90% or more at a guess. Gun is bow mounted 4 inch.

Default Hash Marks for aiming

There is a mod that helps by adding hash marks on the deck gun sight:

CSL Deck Gun Optics

Hope this is helpful.

I've found that leading the target is necessary, if he's moving left to right I have to aim to the right so the shell arrives when he does. There's also a momentum built in, firing on either beam while running at high speed means the shell travels forward while going out to the side. I doubled the muzzle velocity in the cannon's .sim file, not sure if it makes a difference or not. Using this mod;

it's easier to see the actual trajectory.

this is an interesting statement because there does not seem to be any parameter dealing with aiming in the CrewAI.cfg file. is there a parameter missing in this RFB 2.0 file? if yes, that could explain the wild-a## shooting the gunners have displayed from the very start of RFB 2.0.

[CrewAI]

Cannon range 1=2000 ;[m] close range limit

I meant more in the sim.cfg "Max error angle", which would also affect the enemy AI. This is what FotRSU has, with "Stock" values after the ";" comments:
[AI Cannons]
Max error angle=5 ;[deg]3
Max fire range=10000 ;[m]6000
Max fire wait=5 ;[s]12

[AI AA guns]
Max error angle=2 ;[deg]5
Max fire range=1600 ;[m]1500
Max fire wait=7 ;[s]7
You could also maybe noodle in the CrewMember and other upc files in the Save folder, and increase the crew's skill (I'd probably mess the game up), or just have them do gunnery practice. Every time you go to surface, battle surface and shoot a few rounds... Put the best people on the guns, and show 'em how to do it every once in a while - just don't lose track of the situation... Was it lurker or Traveller that had a practice target?...
