The second-generation Speedophile Seashark is a jet ski due to appear in Grand Theft Auto VI, sporting a more angular design than the original model. Jason and Lucia were shown riding one past party-goers in the second trailer, and two more appear in an official Leonida Keys screenshot.
Trailer and Keys sightings
At 2:20 of Grand Theft Auto VI’s second trailer, the second-generation Seashark is visible during a waterside party sequence. Its appearance in that promotional video establishes it as a GTA VI vehicle rather than an entry identified only through background material.
Rockstar promotional imagery also shows Seasharks in the Leonida Keys. The known sightings place the craft in a coastal setting, while the available material does not identify a mission, purchase location, price, performance figure, or modification option.
Speedophile motorboat classification
The vehicle is made by Speedophile and is classified as a motorboat, with motorboat also serving as its body type. Although it is described as a jet ski, the available GTA VI classification places it within the motorboat category.
This is the second Seashark generation. The only stated change from the earlier model is its sharper, more angular exterior form. No earlier-game appearances, variant names, handling changes, technical specifications, quirks, or bugs are identified in the available information.
Unnamed real-world influence
A real-world influence is indicated for the design, but no make or model is named. The available information therefore does not support a precise identification of the watercraft on which the second-generation Seashark is based.
