The ICON.

Strong, fast & innovative.

The STERK 31 is a 9.7 m performance boat crafted with passion, featuring modern Mediterranean design, bold lines, and a focus on pure driving pleasure.

Powered by single or twin Yamaha outboards with up to 700 hp, it reaches 62  knots. With a 530‑liter fuel capacity and a twin‑stepped deep‑V hull optimized via CFD, it offers exceptional stability and handling.

The 31 accommodates up to nine passengers and provides ample deck space, including generous sunbeds and a spacious cockpit.

The Cockpit.

Beating Heart of Power, Precision, and Pleasure Converge.

The driver’s position feels ergonomic, intuitive, and visually stunning. Sport Seats with flip-up bolsters and side support allow seated and standing helming. Angled dash designed for full visibility and glare reduction, even at high speed.

Digital instrumentation includes dual 10″ or optional 12″ Simrad chartplotters, joystick control (optional), and digital switching.
Leather-wrapped steering wheel, stainless throttle levers, and optional carbon inserts complete the premium look.

THE HULL OF FAME.

Secret of Speed.

The progressive hull of every STERK is optimized for maximum speed and agile handling. Extensive CFD testing ensures safe, precise control.

The double-stepped, deep-V hull with strategically placed spray rails increases lift and reduces spray. A new and unique feature is the hook rails at the stern, which, along with negative chines, provide superior grip, reduced heeling, and high cornering stability—a STERK signature.

Lightweight and extremely durable composite materials are handcrafted in our modern facility. The seamless hull-to-deck joining process highlights the exclusive, high-quality engineering.

Precision, cleanliness, and strict quality controls make every STERK a durable masterpiece.

Comfort meets Function.

Experience unmatched comfort with the STERK 31.
U-shaped seating converts into a sun lounge, and passenger seats with a leaning function ensure safe, enjoyable cruising. Bow and cabin storage keep everything neatly organized.
Finished in classic white with silver accents, almond Nautilus upholstery, and EVA soft-teak decking. Equipped with a full electrical system, triple bilge pumps, a CE-certified tank, and a foldable ladder.
