Thanks,Arnauld

Take a look at the
Optical Targeting Correction mod.
The ship lengths are listed in the Recognition Manual, measured to be accurate to what the view provides. The mod corrects a flaw with SH4 (and possibly the entire series of Silent Hunter games from UbiSoft) where the periscopes/TBT views aren't providing an accurate Field of View when measuring with the Telemeter Divisions of the scopes (the vertical and horizontal hash marks on the scope lens).
To be clear, there
are 32 divisions on the scope lens, as it should be for the American periscope. These divisions represent "angular degrees" in distance, each division equals one angular degree in measurement. However, the FoV that the game provides is off when measured at any distance. To measure accurately, an object at 1000 yards distance should read with each Telemeter Division 17.5 yards, or rounded off to 52.5 feet. The truth is, the FoV of the stock game isn't 32 degrees wide, it's 36 degrees wide in SH4.
AND, what makes things worse is that a player who uses the 1280x1024 resolution will have a stock game periscope FoV at 38 degrees wide.
The inaccuracy in the games FoV using an authentic 32 degree scope lens is apparent and should be clearly understood. You'll not be able to accurately judge measurements using the telemeter divisions until the Field of View is corrected for the periscope, for all possible resolution sizes a player uses. This inconsistency in resolution/aspect ratio becomes really apparent with the TBT/UZO views. They are off much worse than the periscope views. With each different resolution a player may choose (depending on his computer system) the TBT representation of the FoV changes like a person changes his socks! Each resolution has it's own viewable size through the TBT/UZO.
Sorry to be long winded on this, but to understand why the Telemeter Divisions aren't used in the stock game is due to these flaws in the games optics. Optical Targeting Correction corrects these issues, giving a player the ability to measure accurately for either range distance, or AoB calculation. Yes, measuring AoB was taught and done through the use of the Telemeter Divisions.
You might want to look at this
"Handout" for understanding what tools were used to accomplish that goal. The "Torpedo Fire Control Manual" explains what a periscope FoV should be and how to judge range with it. It also explains how to check AoB when a range distance is estimated. The first several chapters provide definitions, and give an overall description of the "Fire Control Party" (no they aren't firefighters). Chapter 5 gets into the basics of the periscope and how to use it for calculating a firing solution. You'll notice the handout describes a tool called an Omnimeter that was used to help calculate range and figure AoB without using much math. The Omnimeter is also in the OTC mod.
