It drifted out when he was fighting the Strawhats. I assume that like any ship he can steer it. He just prefers to stay there to keep his activities hidden. The Florian Triangle has had disappearances for hundreds of years presumably due to those massive shadows we saw at the end of that arc. We don't know what they are, but people would attribute disappearances to them and not to a pirate. Those who know otherwise and are turned loose are not in much of a position to blab to others given their disposition.
