bug with depth in GWX

How does speed affect trim control in real life? For example, can a boat's trim be controlled just as well (in terms of accuracy and consistency) at 1kt as it can at 5kts?

I'm not overly familiar with submarine operations, but I have plenty of evidence that surface ships have exactly that problem with their rudder. Ships turn tighter at full speed than they do at slower speeds. This would seem to be the opposite of cars and airplanes, and boats, all of which have wider turn radii at higher speeds. The seeming discrepancy comes about for the simple reason that ships cannot go fast enough to have that effect.

I'm pretty sure that subs of the WW2 variety need to be going at least 2 or 3 knots to get enough bite in the planes to maintain depth properly, which is problematic because it's not much faster than that when noise becomes a problem, as well as vibration causing problems for the periscope.

Never thought about this before - but now that I do, I'm wondering if SH3 (and no doubt naval sims) model this effect...? I have a feeling SH3 does, and will check it the next time I play.

Just found some info about ship turning circles here (not read it yet)

Makes sense.

I think I recently read a post here on Subsim about a mod which reduces periscope visibility and usage at higher submerged speeds.

Yep. I have several actual turning numbers for a variety of ships, both Tactical Diameter at different speeds and time-to-turn in degrees. They can be eye-opening.

That would be h.sie's Realism and Gameplay-Related Hardcode Fixes patch. It does a lot of great things towards improving realism in the game, including fix the Lazy Watch Officer syndrome (with the patch he goes to the bridge every time you surface). It's considered one of the must-haves these days.

Seems the speed vs turning circle factor is modelled in SH3 - I haven't specifically tried to observe it in the game yet but just spotted this in the Ubi SH3 manual:

HINT: Turning your boat demands a minimum speed; otherwise the rudders are not effective. The faster the boat goes, the faster it turns.

Ah, yes! That's it. I've very recently started using the h.sie patch after installing LSH3 2015. I need to read the separate LSH3 manual for the h.sie patch that describes what the settings do. For now, I'm using the default settings that came with the LSH3 installation. I'm certainly appreciating the WO fix! I think I'll try the periscope fix setting as well.

I seem to recall another unfixed bug in SH3 that caused the game to CTD when clicking on any of the three automatic manoeuvre icons on the bottom-right of the crew management screen... Presumably that's still a problem?

I only recall that bug when using the Reloaded hack.
I don't recall ever having it with the newer releases where StarForce was removed.

Yeah, that is correct
