Tried to torpedo a single merchant which I classified as a small merchant (no mistake possible, very recognisable). Measuring the distance with the scope at X10 it gives me the wrong distance all the time. The difference is quite big, while my map and experience tells me it is at around 2500 yards, the scope tells me it is at 5000 yards. Getting closer, the difference stays around double the real distance.

Using GWX 2.1 without anything else. Any ideas?

Thanks!
a) Are you sure you have identified the right ship? Ships have different mast heights, thus it can skew your calculations from the start. And some ships may look quite alike, but with different stats.

b) If you use the stadimeter, is your lower crossline lined over the waterline? It is extremely important that the lower part of your angle follows the waterline, or the angle will be wrong.

c) Stadimeter is best used if the AoB is enough, at least, so that you may see the highest mark on the ship (often the flag mast), at middle-to-close range, and in calm weather. I would approach at least 2000 yards from the target before using the stadimeter. If the target is too far, I would plot an approach to get closer at a good firing angle (1000-1200 yards).

d) If you do all of the above, yet don't get right estimates, you could simply use the compass on the nav map, measure the range to target, and enter it manually in the TDC via the attack map.
