A dive boat classed as a motorboat is due to appear in Grand Theft Auto VI. It debuted in the September 2022 leaks, where a clip of Jason firing a carbine aboard revealed its deck, bow, stern and diving accessories such as oxygen tanks and a life ring. A white example with a partially open cabin and canopied upper deck was later seen crossing the Leonida Keys in the first trailer.
