It may glide silently, but the Frauscher x Porsche 850 Fantom Air sports boat is making some serious noise in the boating world! This all-electric day cruiser just smashed the speed record at the 12th Monaco Energy Boat Challenge, hitting an average of 49.84 knots (that’s 92.3 km/h or 57.3 mph) over two one-kilometer (0.62 mile) runs, beating the previous record at the event of 47 knots (86.9 km/h or 54 mph), set by Lanéva Boats back in 2023.
Now, this isn’t the first time that Porsche has been associated with something nautical. Remember the Hermes Speedster that draws design cues from the 356? However, the Fantom Air is a blend of Frauscher’s nearly 100-year legacy in building high-performance boats and Porsche’s cutting-edge E-Performance expertise. Competing in the Open Sea class, the 28-foot Fantom that dominated in Monaco was a standard production model, finished in a cool Oakgreen Metallic Neo paint job with a closed foredeck.
“We are very happy about the success at the event. It proves that Porsche E-Performance enables top performance not only on the road, but also on the water.” – Jörg Kerner, Vice President of the Macan product line
Porsche supplies the high-voltage battery, electric motor, and control unit as preassembled modules, then Frauscher takes over for the final assembly at their Ohlsdorf shipyard in Upper Austria. At its heart lies Porsche’s impressive 800-volt electric drivetrain, straight out of the Macan Turbo EV.
It features a permanent magnet synchronous motor pumping out up to 400 kW (536 horsepower), and the 100 kWh battery pack can provide a maximum range of 62 miles, with support for up to 270 kW DC fast charging.



When you’re at the helm, you’ll notice some truly unique Porsche details like the tachometer, a start button on the left (just like in Porsche sports cars!), and a steering wheel straight from a Macan. Even the cockpit layout and gauges will remind you of a 911.
The Monaco Energy Boat Challenge is a big deal for sustainable marine innovation, and even Prince Albert II of Monaco, who attended the event, got a detailed tour of the eFantom from Stefan Frauscher, Managing Director of Frauscher Bootswerft.
Also, like with Porsche sportscars available as coupes or convertibles, the Fantom 850 can be had as a Runabout or Air, Frauscher gives buyers two layout options: the Runabout, with a closed foredeck, classic styling, and a cabin underneath, or the Air, which features a center helm and an open bow with seating and lounging space.
Limited to 25 units, the Frauscher x Porsche Fantom carries a sticker price of $604,000. For some context, an Aston Martin AM37 cost somewhere in the ballpark of $1.6-$2.1 million, while the 63-foot Lamborghini Tecnomar was $4.7 million when new.
