[Dockwrecker The Privateer]

I've seen a vid on youtube where there was a glitch where the guy stole a navy ship via flying glitch I think it was, and took off with it, then player light sloops were chasing him and of coarse they were faster.They begun to damage him.I talked to one of my honest friends and she said that a friend of hers did it recently.Is stealing a ship still possible say today?
