With over 25 years of experience in creating and marketing custom watercraft, Rob Innes recently unveiled the Jet Shark . This four-seater submersible invites users to immerse themselves in an authentic underwater diving experience, just as if they were a shark speeding through the waters at over 70 km/h. It is a recreational vessel designed to allow users to experience the movements of a great white shark.
Basically, Jet Shark is a high-performance speedboat with a shark-like design. Thanks to the technology deployed in this innovative vessel, it can mimic the movements of these fish , using thrusts to surface or move underwater. Beyond being a recreational option, this craft can also be used as a traditional boat on sunny days , with its two gull-wing doors fully open.
We've developed a science fiction submersible; meet Jet Shark

Over time, all kinds of recreational boats have become popular thanks to the development and standardization of electric powertrains. This has led to a remarkable democratization of electric battery technology, a technology that has been embraced by a large number of companies worldwide. One of these was Rob Innes , a Londoner with over 25 years of experience in creating and marketing fully customized boats.
Innes recently unveiled a semi-submersible vessel designed as a recreational craft, offering a unique underwater diving experience aboard a spacious, comfortable, and user-friendly boat. This vessel, called Jet Shark , is capable of simulating the movements of a great white shark thanks to its advanced technology.
With its striking design, this vessel clearly demonstrates its ambitious goal of mimicking a shark's appearance. This is achieved through a series of technologies and processes capable of replicating the movements of these fish , both underwater and through the propulsion they use to surface. Thus, while it may resemble the classic concept of an orca, this innovative model has truly broken the mold in terms of body imitation.
From the outside, the Jet Shark appears to be a prototype small vessel that can accommodate up to four people . It features a hull designed to withstand pressure and weight, improving its operation without compromising its design, making it a semi-submersible boat. This allows it to spend most of its time traveling on the water's surface.
Inside, Rob Innes's new boat is described as having a conventional internal combustion engine . This remains an interesting technology in the boating industry due to its reliance on fossil fuels. As a result, the developer opted for a Kodiak Marine 6.2L V8 engine, capable of producing up to 420 hp.
Additionally, thanks to the installation of a series of turbines, the Jet Shark reaches speeds of 72 km/h when submerged to a depth of almost 2 meters . Furthermore, the vessel has electro-hydraulic controls , which are necessary for operating the enormous diving aircraft.
Thanks to this, the Jet Shark can be easily controlled underwater using the rear elevators and the thrust vectoring of the jet engine. Furthermore, the snorkel/camera tube remains above water, while the craft only submerges to a depth of 5 feet. Therefore, it is highly safe because if the craft loses power for any reason, it can surface immediately.
The Jet Shark is said to have about three times the volume of the two-seat Seabreacher.
In terms of infotainment, the developer allows the occupants or users of the watercraft to control the handles via several available screens . This feature clearly demonstrates that it is a means of transport designed for leisure and entertainment. Undoubtedly, it is a recreational product unlike anything seen before in the world, capturing people's attention by offering a unique and exciting experience in the aquatic sector.
Although details about its development and operation have been provided, the company has not yet revealed its cost. Therefore, its biggest limitation is related to price, but it is expected to cost between €200.000 and €300.000.
