Ghost
The Ghost or Ghost Missing is a blue Predator police boat, without working guns, from GTA III. In a mission, Gone Fishing, you are tasked to destroy it. However, if you wait long enough, the driver will run ashore where you can kill him, once you do you can shove the boat back in the water and drive it. It has no radio.
When the boat is entered the name reads "GHOST missing" on the PS2 version. In the Xbox version it is simply "Ghost".
