This is incorrect. To be more specific, the effect where you can't hear a sllow moving ship exists, but it has nothing to do with max speed/2.

Just copy + pasted from another thread:

I checked this and the idea that the problem is related to target speed < max speed/2 is definitely wrong. I can hear a 5 knot conte verde liner (max speed 21 kts) and hakusika maru (max speed 12 kts) just fine. On the other hand, I can't hear either when they are doing 4 knots. It might be a blanket problem with speed < 5 knots (or some number close to it, like 4.37822 knots or something). There may also be other causes. At a guess, the point of confusion is that a *lot* of the games merchants have a maximum speed of around 10 knots. Somebody probably did inadequate testing and jumped to the wrong conclusion.
