MOTION

The Sound of Future.

The Sterk 31e is born from a visionary collaboration. Sterk Yachts’ award-winning German design provides the ultimate performance platform.

Vision Marine Technologies supplies the heart—the revolutionary twin E-Motion™ 180E electric outboards. And to unlock its full potential, world-champion powerboat racer Shaun Torrente of Shaun Torrente Racing integrates race-bred technology, perfecting the balance of power and precision.

This partnership brings technology proven on the racetrack, holding a world electric boat speed record, directly to the consumer for the first time.

A Trinity of Excellence.

The 31WB with silent Power.

Welcome to the Sterk 31e with WET BAR. The pinnacle of German performance engineering meets the world’s most powerful electric outboard drivetrain.

Forget everything you thought you knew about electric boating. This is not about compromise; it is about a new, exhilarating reality.

A silent rush, a powerful connection to the water, and zero emissions. This is the future, and it’s ready for you to command.

The Heart of the Revolution: The E-Motion™ 180E Drivetrain.

Feel the instant torque from two 180-hp electric outboards working in harmony. It’s a combined 360 hp that delivers breathtaking acceleration without the roar and vibration of a combustion engine.

Silent, seamless, and stunningly powerful. The dual E-Motion™ 180E powertrain is a marvel of marine engineering, delivering an experience that is both exhilarating and serene.

Charge anywhere, Anytime.

The 170+ kWh lithium battery delivers up to 70 nautical miles of range at 20 mph, providing hours on the water. Recharging is easy via any standard 220-volt marina outlet for a full charge by morning.

A liquid cooling system maintains optimal motor and battery temperatures, while a touchscreen helm shows battery status, range, and navigation. The batteries last up to 2,000 charge cycles before noticeable efficiency loss.
