How to intercept?

Because the U-boat commander didn't waste his time drawing lines on a chart. The navigator and the plotting party did, using the best available high-tech tools - slide rules and tables of logarithms. Whether you use an HP 11C or beads on a string, without a plotting party we cannot begin to approach the way real U-boat commanders did it

Do you use the stadimeter to measure range? Because real U-boat commanders didn't. Only Typ IIs and the oldest Typ VIIs had them. Is it cheating to let the computer measure the angles for you?

Do you use a periscope with 10x magnification? Because real U-boat commanders had to live with 6x magnification. Is it cheating to get a better view than was ever possible on a U-boat?

Do you use binoculars with a built-in gyrocompass readout? Because real U-boat commanders never had such devices. It's much farther beyond WW2 technology than a scientific calculator. Is it cheating when you use a device which is state-of-the-art a half-century later?

Do you use the mod called RND campaign layers with zigzagging units for GWX and NYGM? Real U-boat commanders had to deal with zigzagging, maneuvering convoys. Is it cheating to know that your contact will almost certainly hold its last reported course?

Do you use the Flaggen chart to tell when a nation has changed sides? Real U-boat commanders had to get that information from radio transmissions, which might be delayed or missed. Is it cheating to know the date South Africa entered the war?

Do you use h.sie's Diesel Damages Fix? Real commanders knew that they couldn't run the Diesels indefinitely at maximum RPM without risking a breakdown. Is it cheating to order "Ahead Flank" and not have to worry about an engine failure, which your crew might or might not be able to repair at sea?

Each of these cases represents a trade-off which we all have had to make, between historical accuracy, game capability, and personal enjoyment. You might feel that using a scientific calculator spoils the immersion of the game - for you. I might feel that using binoculars with a built-in compass readout is just plain wrong - for me. We all play the game to enjoy it, and the way you play it is the right way for you. But there is no wrong way. And there certainly is no cheating in a single-player game. If manual targeting is too hard, turn it off. And go have fun. Because, if you are having fun, you are playing the game just the way you should play it.

First of all, I don't know what a stadimeter is. When I measure range, I do it on the map with a ruler. That means I'm guessing whether the target is at 2400 or 2500 meters. It's somewhere in there. As we've covered in other threads, the range is usually not that important. Even in extreme cases it will only make a 1º difference in the TDC. Additionally you cannot put high degrees of accuracy into the TDC.

As for magnification, I didn't even know that the scope had a magnification switch. As far as I'm aware, however, the magnification only goes to 4.5x so I don't know where the 10x figure comes from. On the Uzi maybe? For weeks I've been sinking ships with the 1.5 magnification provided by the attack periscope–sometimes at ranges of up to 4 km.

As far as I'm aware, the binoculars in GWX do not include a compass. Yes, the Uzi does but the binoculars do not.

I do not use a Flaggen chart (I don't know what it is or how to use it) but so far I've only sunk English ships and those in convoys. I prefer night attacks and if the ship is lit I do not fire on it.

I do not use H.sie's diesel engines, but I don't go flank on the surface anyway. Although I cannot measure how much fuel is used by each setting, I have noticed that flank speed offers at best 1 knot of extra speed. I usually use ahead full. My first action after switching to the IXB was to determine the speed at each setting. I have a paper here on which I have written: 6, 10, 14, and 17. These numbers represent the speed I noticed at ahead slow, one-third, standard, and full. I don't have a number for flank written down because I'm not going to need it.

In conclusion, as I said, imo (which means in my opinion) using a scientific calculator in the game is cheating. As far as I'm aware, the crew didn't even use sine look-up tables. They aren't necessary. Before I learned how to draw the triangles, I used the TDC to calculate intercept courses by doubling the target ship's known or estimated velocity and feeding the data into the TDC. That gave me the right lead angle to travel at 15 knots to overtake the ship so sometimes I had to pad it a bit by, for example, adding another knot to the ship's speed if I felt I couldn't make 15 knots.
