Understanding Kilowatts – What Power Really Means for Electric Watercraft

In the boating world, we’ve traditionally talked about horsepower. But as the industry shifts toward electrification, it’s time to get familiar with a new standard: kilowatts (kW).

If you're curious about the future of watercraft—or already looking to make the switch—understanding kilowatts is key to making smart decisions around performance, range, and power.

Kilowatts vs Horsepower – What’s the Difference?

Horsepower (hp) measures peak power, typically at high RPMs in combustion engines. Kilowatts (kW), on the other hand, is the standard unit of power in the electric world.

1 kilowatt = 1.34 horsepower

But here's the catch: electric motors, like the one in ROXEN, deliver instant torque, smoother acceleration, and maintain power more consistently than traditional engines. So, even if the numbers look similar, the riding experience is radically different.

ROXEN’s electric motor outputs 22 kW of peak power – equivalent to about 30 hp – but delivers that power in a way that feels quicker, quieter, and cleaner.

Power vs Energy – How Long Can You Ride?

•    Power (kW) tells you how strong the motor is.
•    Energy (kWh) tells you how far you can go.

ROXEN features a 5.5 kWh battery pack, which provides up to 75 minutes of typical ride time or 15–20 nautical miles (25–30 km) in range, depending on speed and conditions.

Want speed? ROXEN can hit 30 knots (55 km/h).
Cruising more casually? Expect optimal efficiency at 15–20 knots.
Charging? Plug it into a standard 230V outlet and you'll be fully recharged in just 2–3 hours.

Why ROXEN Uses Kilowatts – and Why You Should Too

We believe in precision, simplicity, and smarter boating. Kilowatts offer a clearer picture of performance, especially for electric systems. Here’s why:

• Better understanding of real-world energy usage
• Easier comparison between electric models
• Clearer range expectations based on riding style
• Smarter planning for private or rental use

And thanks to smart features like geofencing, app control, GPS tracking, and over-the-air updates, ROXEN gives you full control of every kilowatt—whether you’re managing one craft or an entire fleet.

Why It Matters: The Future Runs on Kilowatts

Horsepower might feel familiar, but kilowatts are the future—especially when you want clean, quiet, and powerful rides with zero emissions and full digital control.

With ROXEN’s 22 kW electric motor, modular 5.5 kWh battery, and seamless smart integration, you get a next-generation watercraft experience that’s fast, safe, and future-ready.
