Sterk 31WB

The STERK 31WB version presents itself with a well-designed bar, dining lounge, and kitchen for wonderful moments with friends or family.
Comfortable bathroom, large aft platform, extra spacious sitting area, wet bar with refrigerator, and kitchenette will ensure maximum comfort during your stay on board.

The Supersport hull shape has been designed for fast running and agile response. It features a twin stepped deep V layout with strategically placed spray rails to enhance lift and reduce spray. Hundreds of hours by CFD testing resulted in exhilarating performance while maintaining a safe, predictable handling.

A novel feature unique to STERK are hooked rails on the aft planing surface. Combined with our negative chines, they provide great bite and less heel in fast turns and prevent spinout while evoking a great feeling of confidence synonymous with the STERK name.

Extremely stable and lightweight composite materials are handcrafted by our specialists in a completely new manufacturing facility.
