Ducted Propeller (Kort Nozzle) – High-Efficiency Marine Propulsion System
Product Overview
Our Ducted Propeller (Kort Nozzle) is a high-performance propulsion solution that combines a fixed foil-shaped shroud with a precision-engineered propeller to boost thrust efficiency by 15–30% compared to open propellers. Ideal for heavy-load or space-constrained applications, it is crafted from marine-grade copper and certified by CCS, BV, DNV, KR, NK, GL, ABS, ensuring reliability in demanding conditions.
Key Features & Benefits
✔ Enhanced Thrust Efficiency – Nozzle design accelerates flow, ideal for tugs, trawlers, and low-speed vessels
✔ Heavy-Load Optimization – Perfect for high-thrust, limited-diameter applications
✔ Superior Maneuverability – 30% better bollard pull than open propellers
✔ Reduced Cavitation – Shroud minimizes tip vortices, protecting blades
✔ Corrosion-Resistant – Copper construction for saltwater durability
✔ Global Certifications – ABS, BV, DNV, CCS, KR, NK, GL approved
