Seabob F9
The Flagship Cayago Watercraft — Designed by Studio F. A. Porsche
The Seabob F9 is Cayago AG's flagship electric underwater scooter and, in its F9 S configuration, the most powerful watercraft in the Seabob range. A 2.6 kW drive (3.6 kW on the F9 S) delivers 60 TP of thrust (84 TP on the F9 S) through the purpose-built e-jet power system, letting a single rider glide across the surface or submerge for silent, zero-emission exploration of the anchorage.
Every F9 is designed by Studio F. A. Porsche and built in Germany — engineered in Stuttgart and produced at Cayago's manufacturing facility in Bad Salzuflen. Its lightweight body combines titanium, magnesium and special ceramic coatings, keeping the unit at 22.9 kg (25.9 kg for the F9 S) so two crew can lift it off the swim platform without a davit.

Flagship Power
The F9 sits at the top of the Cayago range. With a 2.6 kW drive and 60 TP of thrust — rising to 3.6 kW and 84 TP on the F9 S — it is the most powerful Seabob in the fleet and the reference point for every other electric underwater scooter on the market.
Charter-Guest-Safe
Electric drive means zero emissions and zero fuel on the swim platform. At 22.9 kg the F9 is light enough for two crew to hand overboard, and the simple hand-grip throttle lets any adult guest ride it confidently after a short brief.
German Service Network
Designed by Studio F. A. Porsche, engineered in Stuttgart and produced in Bad Salzuflen, every F9 is supported by Cayago's authorised European dealer network — including Mercer Yachting's Malta desk for Mediterranean service, warranty and spares.
Why the Seabob F9 for Your Superyacht?
The Seabob F9 is the benchmark electric underwater scooter for charter and private yachts. It carries a single rider on the surface or below it, powered by a purpose-built e-jet power system that replaces the petrol PWCs many charters used to keep on deck. Because it is fully electric, the F9 can be stowed and charged inside tender garages and technical spaces without the fuel-handling and ventilation headaches of internal-combustion watercraft — one of the main reasons captains and ETOs increasingly specify Seabob units on new-build and refit toy packages.
Flagship status on the F9 means two things. Firstly, the drivetrain: 2.6 kW and 60 TP of thrust on the standard F9, stepping up to 3.6 kW and 84 TP on the F9 S, give riders the pull to plane at the surface and the reserve to hold depth against current when diving. Secondly, the build: the body combines titanium, magnesium and special ceramic coatings, keeping the all-in weight to 22.9 kg on the F9 and 25.9 kg on the F9 S so deck crew can handle it without a dedicated crane.
Mercer Yachting supplies the Seabob F9 through Cayago's authorised channels with full manufacturer warranty. Our Marsaskala, Malta desk delivers to every major Mediterranean yacht hub — Antibes, Palma de Mallorca, Monaco, Genoa, Athens and Split — and coordinates worldwide freight to any nominated port or agent. We can build complete Seabob packages combining the F9 or F9 S with the full Cayago accessory list: Quick Charger, SEABOB Bag, Cover, F9 Rack, Pilot Belt System and Lifting Dock.

Frequently Asked Questions
What is the difference between the Seabob F9 and the F9 S?
Both units share the same Studio F. A. Porsche body and e-jet power system. The standard F9 uses a 2.6 kW drive delivering 60 TP of thrust at 22.9 kg; the F9 S steps up to a 3.6 kW drive, 84 TP of thrust and 25.9 kg. The F9 S is the flagship-of-the-flagship configuration and the most powerful Seabob on offer.
What is the maximum dive depth of the F9?
Cayago does not publish a maximum depth figure on the F9 product page. Riders should follow the manufacturer's usage instructions and Cayago's recreational free-diving guidance. Mercer Yachting can share the current owner's manual and any dealer-issued limits when you request a quote.
How long does the battery last per charge?
The standard Seabob F9 delivers 40 minutes of operating time on the base battery, or up to 60 minutes when specified with the Battery Capacity Plus option. The F9 S comes with Battery Capacity Plus as standard and delivers up to 50 minutes — the higher-output 3.6 kW motor draws more energy, so runtime is shorter than the F9-plus despite the same battery. Real-world time varies with thrust level, rider weight and water conditions.
Is the Seabob F9 safe for charter guests to use?
Yes. The F9 is fully electric with zero emissions, weighs 22.9 kg so two crew can handle it off the swim platform, and is controlled with an intuitive hand-grip throttle that any adult guest can operate after a short crew brief. Multiple thrust levels let crews set conservative limits for novice riders and open the full envelope for confident ones.
Can Mercer Yachting service the Seabob F9 in Malta?
Yes. Mercer Yachting operates from Marsaskala, Malta and acts as your Mediterranean point of contact for Seabob F9 sales, warranty and accessories. For larger repairs we coordinate with Cayago's German facility in Bad Salzuflen through the official service channel, so your unit is always handled by factory-trained technicians.
What warranty comes with a new Seabob F9?
Every Seabob F9 supplied by Mercer Yachting arrives with the full manufacturer's warranty from Cayago AG, registered in your vessel's name. Exact warranty terms are issued by Cayago at the time of order — we include the current warranty document in every quotation so you can confirm coverage before confirming the spec.
Which Seabob accessories should a superyacht order with the F9?
Cayago offers a dedicated F9 accessory set: Quick Charger (to cut turnaround between guest sessions), SEABOB Bag and Cover (for garage or tender-deck stowage), F9 Rack (for fixed mounting), Pilot Belt System (for tow-along use) and the Lifting Dock (for crane handling on larger vessels). Mercer Yachting typically recommends the Quick Charger, Cover and Rack as the minimum specification for a 40 m+ yacht running daily charter.
How does the Seabob F9 compare with an electric hydrofoil (eFoil)?
They are complementary toys, not competitors. An eFoil lifts a single rider above the water on a foil at speed; the F9 carries one rider on or below the surface using an e-jet power system. The F9 excels at anchorage snorkelling, underwater exploration, zero-emission cruising and guest experiences that don't require balance training. Most charter yachts carry at least one of each.
