In RFCE naval units do get destroyed by the plague 

Lately I've been removing plague in WB as soon as it appears because I hate both the plague and the ways around it, though nowadays I play Civ5 mostly.
Oh, I have no doubt that it makes sense. I just didn't think that anyone had poked around in the code to see if it was true.
"1) As soon as plague hits one city in the world, move all of your units to a tile 3 spaces away from every city."
Have fun playing Egypt with that strategy!
