To each his own. NYGM TW is not really a mod for those who just want a 'hoopless' game to play, you know. But the hoops are where the feeling's at for some :up:

IIA (Not modelled in AoD) :damn:
IIC (Not in SH3) :damn:
IID ~ 170
VIIB ~ 180
VIIC 190
IXB 170
IXC (and /40 variants) 180
IXD2 190
XXI I don't know (Never used it in Aces)

But not like flooding, ah hell everyone who played aces will sure know what i mean!!!!

And i'm think the boat should sink VVVVEEEEERRRRYYYYY slow, 2 preventing issues with time compression.

And ONLY if the boat is DIVED and STOPPED!!!!!COMPLETLY STOPPED!!!!!!!!!!!!

You only took water when you were either silent running, or below crush depth, because the bilge couldn't keep up with the water coming in. I know exactly what you mean, when you were down below too long, you had to blow ballasts. As for standing still at PD and waiting for a convoy... no way, but the interface at the map was a bit better, so setting up your position right was a lot easier. OH.. and I think the escorts were mostly dependant on visual detection, even in late war.

I, for one thought it was a good idea.

It has been ready since we tracked down the crash dive bug as outlined in this thread ==> http://www.subsim.com/radioroom/show...ash+dive+blues

It works great and is a hoot. You really need to plan your attack run otherwise you might over shoot or not get back to persicope depth in time.

Will be released in the NYGM Tonnage War V2 very shortly.

Hover. Hover. Hover.
OR, make it a realism setting.

Outstanding, looking forward to it:up:

God heavens! What's going on here? :o

Well, it's nice to see I'm not the only one who doesn't like boats ability to keep its balance at 0 if submerged.
Because the system is what it is and there is no mod for this (and I doubt if there ever will be if it's hardcoded), I'll never give my speed go under 2 knots.

Uber Gruber 05-30-06 10:52 AM

And will NYGM TW 2.0 be ready before WaW 1st patrol Teddy ? I'm sure thats the goal but what is your gut feel ?

Cheers....:yep:

greyrider 05-30-06 11:04 AM

from what i read on this post, you guys are trying to sell the notion that a submarine cannot stay at a constant depth without speed. your saying that without speed the boat will sink like a stone.

let me ask you a question: if there are no systems aboard that can conpensate to maintain a constant depth, then there is also not a system that would keep the boat from listing , am i correct?

so if your going to maintain the position of speed being the primary factor in keeping depth, then i guess speed is also needed to keep the boat from listing.

so now, without speed,you have a real problem with your boats, youll never be able to attack ships, because your view threw the scope will either show you ocean or sky.

me, i let the trim and drain systems take care of my boats ballast and trim. this way, i can hover as long as my boat is balanced, whether bow to stern, or port to starboard.

Sailor Steve 05-30-06 11:10 AM

Sorry, but every ship and boat has a system to keep it from listing. It's called a KEEL, and it consists of a very heavy piece of steel running the entire length of the the ship, and is also aided by heavy ballast made of sand, concrete or in a submarine's case the batteries. The ship will not list while sitting still, unless it has taken on additional ballast in the form of damage allowing water in on one side or the other.

It is a known fact that WWII-era subs could not sit still underwater for any length of time without either rising or sinking. They MIGHT be able to pull it off for a while by adjusting the tanks, but that requires allowing ballast water in or blowing it out, and either one is very noisy, thus defeating the point of being silent.

Listing? Please reply when you have some real facts at hand.

U-Bones 05-30-06 12:33 PM

The inability to maintain a specific, exact and constant depth does not neccessarily mean that you are on a fast track to crush depth. The trim of the boat, even if inappropriate for maintaining the exact desired depth, is in fact appropriate for a specific depth, presumably close to the desired depth. Relative stability is only a few feet away in most cases, although relatively slow degradation is to be expected under normal circumstances.

I would be more enthused if we had pumps and more than 4 blows of the tanks.

All that said, I can deal with it either way - I usually avoid all stop in game anyway, for the same reasons I surface only for air or recharging in rough seas.

CCIP 05-30-06 12:53 PM

Far from being on fast track, however! I believe the sink rates we're speaking about here are very small - after all, they're compensated by only a couple of knots forward speed.
It would take you quite a while to get to crush depth.

On the other hand, what's the incentive to stay still, anyway? We've already established that a U-boat needs the dive plane control to keep periscope depth, for which it needs to be moving, and down below... what difference does a couple of knots make? Both in SHIII and in reality, there is little if any difference between silent running and staying still (in fact, the blowing/flooding of tanks to keep still would likely be a lot noisier than the electric motors)

i did, at the bottom of my post was a link, maybe you didnt see it, wheres yours?

by the way sailor steve, did you ever hear of neutral Buoyancy? i want to see your proof steve, and i dont want to see it from novels.

Heibges 05-30-06 02:42 PM

If you never stop your engines, would ever notice the hummingbird effect?

If I never go slower than 1kt, would I notice any difference by using the mod?

My apologies, I stand (partly) corrected. All it says is that the boat can list if both saddle tanks are not filled equally. As to neutral bouyancy, that's what this topic is all about. It is a state very difficult to obtain in real life, at least without the aid of modern computer-driven ballasting systems.

And no, I very rarely read novels-my library is mostly reference and technical books.
