SEABOB

Seabob F9 S

Name: Seabob F9 S
Brand: Seabob
Availability: InStock

Top-Tier Electric Underwater Scooter — German Engineering, Porsche Design

The Seabob F9 S is the high-power flagship variant of Cayago AG's celebrated F9 watercraft. Delivering 3.6 kW of motor output and a thrust performance rating of 84 — a full 40 percent above the standard F9 — the F9 S is engineered for owners, guests, and charter operators who want the most capable electric underwater scooter on the market. Paired with the battery-capacity-plus option, the F9 S offers the longest runtime in the Seabob range, making it ideal for back-to-back guest sessions from the swim platform.

Designed by Studio F.A. Porsche and hand-assembled in Bad Salzuflen, Germany, every F9 S carries the same obsessive build quality and industrial design pedigree that has made Seabob the standard-issue water toy on the world's leading superyachts. Cayago AG is headquartered in Stuttgart and operates its own service network, giving owners direct access to German factory support and genuine spare parts throughout the vessel's service life.

Maximum Power & Runtime

With 3.6 kW of motor output, an 84 TP thrust rating, and Battery Capacity Plus as standard delivering up to 50 minutes of continuous operation, the F9 S is the highest-thrust F9 variant on offer. Ideal for owners who refuse to compromise on performance.

Built for Charter Use

The extended runtime and higher thrust let charter crew rotate multiple guests back-to-back without the constant battery swaps of lesser underwater scooters. Reinforced build quality from Cayago AG holds up across demanding Mediterranean charter seasons.

German Service Network

Cayago AG maintains its headquarters in Stuttgart with manufacturing in Bad Salzuflen, Germany. Owners benefit from direct factory support, genuine spare parts, and a global authorised service network — a very different proposition from low-cost underwater scooter clones.

Frequently Asked Questions

What is the difference between the Seabob F9 S and the standard Seabob F9?

The F9 S is the top-tier variant of the F9 platform. It has a 3.6 kW motor (vs 2.6 kW on the F9), an 84 TP thrust rating (vs 60 TP on the F9), and weighs 25.9 kg (vs 22.9 kg on the F9). Battery Capacity Plus is included as standard on the F9 S, delivering up to 50 minutes of operating time. The F9 S is the right choice for owners who want maximum power and a single-specification unit with extended runtime built in.

What is the depth rating of the Seabob F9 S?

The Seabob F9 S is designed for surface and near-surface use with controlled dives. For the authoritative depth rating applicable to your specific configuration and battery option, we always defer to the current Cayago AG operator manual supplied with the unit. Mercer Yachting provides the official documentation with every delivered F9 S.

What does "battery-capacity-plus" mean on the F9 S?

Battery Capacity Plus is the larger-capacity (1.2 kWh) battery specification that comes as standard on the Seabob F9 S and is optional on the standard F9. On the F9 S, Battery Capacity Plus delivers up to 50 minutes of continuous operating time. On the F9, Battery Capacity Plus extends runtime from the 40-minute base to up to 60 minutes. If longest runtime matters, the F9 with Battery Capacity Plus is the longest-running configuration; if maximum thrust matters, the F9 S is the pick.

Is the Seabob F9 S safe for charter guests?

Yes. The F9 S is the same platform used across the global superyacht fleet and is designed for operator-controlled use with variable piloting modes. We recommend that every guest receives a full briefing from crew before use, understands the throttle behaviour at the higher power levels, and wears appropriate buoyancy aids. For intensive charter use we typically recommend pairing an F9 S with one or more standard F9 units so less experienced guests can ride at lower power while the F9 S is reserved for confident riders.

Can you service my Seabob in Malta?

Mercer Yachting operates from Marsaskala, Malta and coordinates service, spares, and warranty work with Cayago AG's authorised service network. Any Seabob supplied by Mercer Yachting comes with full factory-backed warranty, and we handle scheduling and shipment of service jobs so crew do not need to manage the logistics themselves. Contact the team for a service plan tailored to your yacht's cruising itinerary.

What warranty comes with a Seabob F9 S from Mercer Yachting?

Every Seabob F9 S supplied by Mercer Yachting is delivered through authorised Cayago AG channels with full manufacturer warranty. Warranty terms, duration, and coverage are governed by Cayago's current policy at time of delivery and are documented in the operator manual supplied with each unit. We are happy to share the applicable warranty terms in writing before order confirmation.

What accessories are available for the F9 S?

Mercer Yachting can supply genuine Cayago accessories alongside the F9 S, including docking cradles for garage or swim-platform stowage, additional chargers for dual-unit rotation, spare batteries, and transport cases for shore moves. We recommend discussing your yacht's storage layout and expected charter usage with our team so we can specify the right accessory bundle from day one.

Seabob F9 S or an eFoil — which should a superyacht carry?

They serve different guest experiences. The Seabob F9 S is an underwater scooter — guests lie on the craft and glide at and below the surface, and no learning curve is required. eFoils lift the rider above the water and demand a meaningful learning curve before guests can ride confidently. Most 40 m+ yachts carry both: one or two Seabobs (ideally mixing F9 S and F9) for universal guest access, and one or two eFoils for guests with the time and appetite to learn. Mercer Yachting can specify and deliver both on the same order.
