Nope, these are not for any naval simulator, these are vessels that can be downloaded and put in Flight Simulator.
But they haven't got very realistic dynamics though. I have tried a few in the past with FS9 and it's just like taxiing a plane, but on water. So it's not about sailing really, just nice to look at.
I don't know if recent addons for FSX have much better dynamics, but I doubt it.
