Heya guys. I just started playing the game about a week ago and I'm having quite a lot of fun despite the fact that it's mostly an alien language to me so far. I really didn't find that the manual or in game tutorials properly explained the instruments and the proper way to utilize what's available to someone that has little prior knowledge of these things. I've spent a lot of time on this site (more then I've even been playing) watching the training videos and reading the documentation and it's helped me quite a bit but there are still a few things that I'm just not connecting the dots on and was hoping someone could help explain them to me. I know some of the questions are probably already answered and I overlooked them or simply didn't understand such is the case with a couple of the videos (the one that I thought would answer all of my questions had such horrible audio I simply couldn't make out what he was saying) so I apologize for any inconvenience.
![]() Ok, as I said I've already picked up on quite a bit and am now playing on 100 realism with the exception of the cams which I'm leaving on only to check on my shots after I make them to verify if what I did worked. I don't use them to do anything else. I am starting to have some luck getting the measurements right but these following points I'm really not fully grasping. (Most of it LOL) For one, the tool to check the distance on a ship after identifying it. There appears to be a slight graphical issue with the tips of the mast when lining the images up and I'm not sure if I should be waiting for that last portion of the mast to flicker into view and place the image at the absolute top of that or should I ignore the portion that's flickering out of view and focus solely on lining it up with the top of the mast that is constantly visible? Second is the AoB I believe it's called? I believe it means angle of bearing? From what I believe I understand that's the angle the torp will impact the ship at from the current setup. My problem is I simply don't understand how to calculate it short of guesswork. My guessing has been getting better and I managed to get several sinkings last night but I'm sure there's got to be a more sound method to get a precise measurement without guesswork right? Another is in regards to tracking a ships position with the map. I have no clue what the conversion is between feet and NM's or how to properly use the tools (considering I'm not entirely sure I'm getting the distance right in the first place) so I'm really confused on how to properly note with any measure of certainty where on the map the targeted ship is in relation to me in order to track it's progress which I assume if I can figure that out then determining the AoB will be easy after that. When it comes to tracking speed, I've been using the method to time how long it takes the ship to pass the crosshairs and that's been pretty accurate for me but depends entirely on being close enough to identify them to know the length of the ship I'm measuring. Again I believe understanding the above point will likely help with this also. I've also been curious about escorts. I've read a few things on this board about them and I recall one set of pictures that showed early war destroyers ranges at about 120 feet yet there are numerous instances where I'm still being pinged at below 200. In regards to that I'm not entirely sure exactly how deep I can go. I believe the red water mark on the depth meter is somewhere around 300. I haven't tried to go beneath that point as I assume it'd be bad for me but I wonder if it's possible to go that low for any measure of time without getting stuck under. lol I'm also curious what effect speed has at those depths as there where numerous occasions where I was traveling at great depths and forgot to change from flank speed and used time compression. When doing that my ships would suddenly start taking a ton of damage and I couldn't identify a source as it doesn't appear to be a plane or destroyer and I was in very deep water so it wasn't the floor. I assume it was the constant speed at the pressure those depths bring that did me in? I'm nervous about using high speed when evading escorts while that's a possibility. lol So yea, I ramble a bit if you can't tell. lol. I'm using the stock game 1.5 U boat missions and any help or advice would be greatly appreciated. I'm really trying to learn and you guys have provided some great vids and articles that have helped me a bunch already, but it's just those few points I can't grasp in the first place. ![]() Thanks. ![]() |

Not much time here, so I'll try to hit on the key points.

Best way I can put it to you is like this. You're driving in your car, and you come up on somebody you need to pass- they're in your lane. They are 0 degrees off your bow. As you pass them and they are directly beside you, they are 90 degrees off your bow. That number increases until you pass them completely, and they are 180 degrees off your bow. The purpose of the angle off the bow calculation is to tell your TDC (Torpedo Data Computer) which way your target is going *relative to you*. Other guys can explain it better, I'm sure, but that's the start of it. Quote:
![]() If you zoom in on your map, you should have a bearing disc around your boat. Draw a straight line along the bearing you see him at, out to the distance you plugged in, and there ya go. If you take multiple "snapshots" of his position, you can perform a rudimentary TMA (Target Motion Analysis) and that will give you his course, thereby allowing you to use your protractor and figuring out the AoB with 100% certainty (provided your measurements were correct with the stadimeter) Quote:
If you wind up with something like 275 knots, you messed up a little ![]() Cool thing about doing this is while you bide your time waiting for the next time to raise your scope, you can look at your attack plot and plot his position (he was at bearing 300 at 1200m, so X goes here). Then pop your scope up a minute later, and you have another x. Connect the dots and you'll have your course, your AoB, and at the same time get your speed down. Torpedo solution ready, captain. Quote:
If you're *damaged* however, you are in trouble. Never ever go down to test depth if you're damaged. Quote:
![]() Seriously, though, time compression while submerged is generally a bad idea. Quote:

Thanks! I think you pretty much covered the area's I needed. I know it may seem silly but I'm really new to all of this period so I just need to understand the concepts first to really understand what's going on and I think you just helped me do that. Thanks again.

What Fishie said was all spot on, but I'll try and give my perspective on the points you're asking.

Secondly, the depth you can go to depends mainly on the boat your using. Generally S-boats won't go under 250ft (if i recall.. haven't played in a while), compared to the Gatos and Balaos that can go 600ft+.Also, the deeper and longer you stay 'in the red' the more damage you do to your boat gradually over time which, when accumlated in enough quantities means you'll suddenly realise you can't go to the surface when you want to.

Thanks very much for the welcome.
![]() Couple things. You mention the stadimeter is more of a snapshot tool then rangefinder? The problem I seem to be having is getting an accurate read with the thing at all. I'm somewhere about 5k out on a Large Modern Composite yet the choppy seas and finding where to place the second image are producing wildly varying distances by as much as 1k between the two most extreme amounts of 4500 and 5500, which is also making that method of determining speed inaccurate with ranges from 40-100 knots. lol Is there a better way to find range? I know you can with Sonar but I've read it's not so accurate all the time itself and I'm really not sure how easily I can get myself into trouble pinging other ships. Are merchants able to tell when I'm pinging them or is it only escorts? And how careful should I be about pinging with escorts nearby? Say there's no warship within 10 degrees (couldn't find the degree symbol on my keyboard) of the ship I'm pinging for distance, would would an escort beyond that range still detect what I'm doing? For that matter, how high can I surface myself without making my sub profile too obvious? Do I always need to stay at periscope depth while occasionally peeking out to be safe or can I let myself rise 5-10 feet in choppy seas so the waves don't make it so difficult to get a proper reading. I understand the waves also make it harder for them to spot me but at such a range I don't think they'll spot my quick periscope peeks even if I raise it, but I'm unsure what the effect of decreasing my depth would do otherwise. As to the realism stuff, I'm not really having trouble with most of it. Fuel, air, battery and all that are simple enough and in my early war campaign I'm having little trouble sneaking into convoys and escaping after my attack. I simply don't understand all of it yet but I've been having a lot of success with it anyway. My only problem is with feeding the info into the tdc for proper attacks once I sneak in because of the varying ranges I'm getting and the fact that I'm still having a tough time identifying the AoB. I understand it's my location from the perspective of their ship but it's tough to identify what that is. I find I'm miscalculating by some fairly large margins, by as much as 30-40 degrees. I'm going to try rereading those tutorials you mentioned and see if they make more sense to me now. *crossing fingers* lol And thanks again. I really appreciate the help. ![]() Edit: Also, which mods would you really suggest? I haven't really taken much of a look there as I've been trying to get the basic fundamentals down before I really do anything else but plan to take a look once I do. ![]() Edit Again: I looked up the tutorial you suggested and I agree it appears to explain everything I really need it to, except I'm having a problem making out half of what he's saying because his voice isn't very well contrasted to the game noise. There are entire portions of those 3 video's that I simply can't make out because I can't hear what he's saying. ![]() I'm rewatching the sonar one and the sound for it doesn't seem as bad as it was for the first two video's so that's good. I actually think this video has helped me understand how it's done, at least under the assumption for sonar error. Definitely should help though. ![]() ![]() Last edited by Way2co0l; 11-17-10 at 08:47 PM. |

Turn off the "no stabilize view" to help in a heavy sea. It may be a bit gamey, but for practicing your stadimeter work, there's no better aid.
Keep in mind that at long ranges, you're best bet is to get a feel for where he's heading, cut him off, and let him come to you. THEN once you have a good clear sight picture, start with the stadimeter work. I use the stadimeter primarily as a targetting tool, and try to get the best solution I can with it. Some use it as a snapshot, some don't use it at all (Dick O'Kane method). For me, I've learned to use it, and it serves me well. Your mileage may vary ![]() Quote:
Make sure you pick up the JGSME and read how to use it, though. That tool is a Godsend. Welcome aboard ![]()

Thanks again guys. I'm messing with stuff to see if I can figure it out and can't seem to figure out how to alter my range circle once I place it. I seem to have to remove the old one and place a new one. I can move the old one, I just can't seem to alter the range it shows. lol.
Anyway, you both mention sitting in position ahead of the targets but how does that work in a convoy situation? It seems to me that if you setup ahead of the targets line waiting for them to come into position then you're going to be exposing your side to the lead escort the entire time which would likely result in an easy sniff for them I'd assume. So far whenever I've been approaching a convoy I generally have to take a wider angle on it at first before turning into the lead escort which ultimately presents a narrow profile while bringing me behind him but still quite ahead of any flanking escorts, but to do so I can't just sit entirely still or I'll fall behind and into the flanking escorts path. That usually puts me in a good position to strike and plenty of time to maneuver out of danger after I hit. The problem is just the measurements to hit. I've rewatched the video's a few more times now and I think I've pieced together most of what he was saying so I think I might be able to pull it off. That is once I become more comfortable with the tools as my trouble expanding the circular range tool demonstrates. lol. I just need to practice and mess around with them more to get it straight I think. Not entirely sure what decks awash is or what it's purpose is? lol. I'm that much of a noob. ![]() I'll take a look at the mods you guys mentioned later tonight. I think I'll practice the convoy raiding training and see if I can manage to hit anything without too much blind luck. hehe |
