At least for your own ship. I'm pretty sure the captain would know where his pump and magazine were located. I like the idea. Once they add 3d ports I think it would something worth taking a look into by the devs. Being able to click a button that lets you look at your ships armor setup, angle of the hull, were critical items are located, etc etc. In my head I'm seeing it kind of like WarThunders armor/internals view (Not saying it should be emulated, just that's how I imagine it). Sure players can just screenshot those to learn the best areas to shoot but most won't take the time to study every ship class in the final release.
Pictures for how I'm seeing it in spoiler.
