User blog comment:Coyote and Smart Alek Co./Owning enemy warships?/@comment-1997676-20110610223029

I was on test during that incident (this was the same incident where the Ship of the Line was available), it was unclear whether they were intentionally released or if it was somehow an accident. Considering that they were removed shortly after and still haven't been released, I would think it was accidental.

I think I would enjoy using an undead ship, especially as a "theme" option for those long-promised customizable ships. Other players should be able to distinguish you from an enemy by looking at the name, the sailing speed, etc.
