An unnamed speedboat is due to appear in Grand Theft Auto VI, seen along the Vice Beach coastline and racing across the bay in the first trailer, as well as moored behind Jason and Lucia in official artwork. Essentially a bowrider take on the Speeder's silhouette without the extra bow railings, it is based on the Frauscher 1017 GT with influence from the Riva Aquariva Super and Cranchi E26 Classic.
