underwater transparency of surface ship hulls

[Baz000]

Really appreciate the addition of the new ship wakes for all the surface ships, but something sticking out to me has been the fact you can see through the water and see the red undercoat on the hulls almost completely as well as the turning screws... This IRL is never seen underway (while moving) as far as I know and especially on an aircraft carrier... You can look at page after page of photos and you will never see the screws (propellers) of the aircraft carrier turning or even the shaft connections to the hull of the ship, let alone the huge rudders on the carrier... This is due to the depth of the water. Really, the only time you can see such components is in dry dock

Case in point:

IRL you really don't see much of anything below the waterline, especially while underway, maybe its still all WIP but from the point of the waterline, you would only maybe see a little bit below the surface, but certainly not all the way to the screws or the rudders or the sonar on the bow... You'd see below the waterline a tad bit if even that IRL, and you'd see the reflection off the water of the superstructure of the ship from the waterline up.

 

IDK to me it just looks off compared to what your eyes would actually observe in reality, also the color of the water / tinge makes a difference too depending on what geographic region you are underway in... But even in the lightest light blue tropical waters you don't see such detail below the waterline while underway, maybe perhaps stationary if you squint really really hard.

 

Majority of these ships, the only way you'd see such detail below the waterline is in dry dock.

Sea Water transparece has affected by salitity and other conditions. That has variable on the world sea surface.

That is not only a filter, need seek some realistic.

Be that as it may, you would never see such ship features underwater as you currently do in DCS, especially while underway and this is due to the wake of the ship, which isn't only just because of water being displaced around the hull but also by the propulsion system.

Regardless of size of vessels, even small 20ft long pleasure boat... You can't see the screws turning or the rudder / underwater motion of engine rotation as steering drive in case of outboard or inboard outboard motors.

You only see the wake, practically everyone ever gone boating knows this, it's fairly basic.

 

here is USS Nimitz in a high performance turn:

If you could see below the waterline, then surely at such a high list the propellers on the port side (left for you land lovers) would have a far higher chance of being visible, since in that turn the port side props would be closer to the ocean surface and the same such phenomena would also be present with the huge port rudder.

Underwater diving environment (I haven't watched the video you posted yet, but I imagine they are coming from a diving underwater perspective) isn't the same thing as a ship underway, making wake.

There's also the reflection of the water surface to deal with. The measuring instrument shown in that video on sea clarity is tested by looking straight down. I scuba dive a couple times a year, and sure if there's good visibliity you can see the bottom 20m down, looking straight down. But at any angle you will not be able to see that deep due to the light bouncing off the surface of the water. 

Even if the ship weren't creating a wake, and you were in the clearest water possible, you wouldn't see the screws unless you were looking straight down at them.
