If you want to play fast and loose with a CV, fine, do it with one we own the port for.
Hiding CV's is an accepted part of gameplay. Spying to get one back stinks, understandable, but its still fishy.
As is switching sides to take command one one so you can sail it back to where it can be sunk.
Do it the old fashioned way, EARN it. Most maps its really not that hard to find a CV if you are willing to invest a half hour of time looking. Once you have it spotted, get together a pilot or 3 and go kill it.
