Gori 20x14x3RHS Folding Propeller – 3-Blade, Ø20", Pitch 14", Right-Hand, for Sail Drive SD40–60

The Gori 20x14x3RHS-SD40-60 is a state-of-the-art 3-blade folding propeller designed for sail drives such as SD40 and SD60. Since its launch in 1994, it has earned industry acclaim including the prestigious DAME and HISWA Awards. This propeller is engineered to deliver the speed advantages of a folding propeller under sail while providing strong thrust under engine power, even for larger sailing yachts and motor sailers.

Key Features

• Diameter: Ø20"
• Pitch: 14"
• Blades: 3-blade, folding design
• Rotation: Right-hand (RH)
• Compatibility: Sail Drive SD40–60
• Engine Power Range: 7 kW (10 hp) to 221 kW (300 hp)
• Overdrive Function: Adjustable pitch in forward motion, enabling efficient motor operation at lower RPMs
• Efficiency: +15% in both forward and reverse thrust compared to conventional folding or rotary blade propellers
• Noise/Vibration: Reduced through advanced wing curvature and balanced rotation
• Drag Reduction: Low-profile folding design increases boat speed under sail
• Anti-Fouling: Blade geometry prevents debris entanglement during sailing

Saildrive Hub Design

This saildrive-specific propeller includes a flexible core hub that functions as a shock absorber and provides electrical isolation between the propeller and the saildrive leg. This complies with manufacturer requirements and ensures compatibility with systems such as Bukh, Sonic, Volvo-Penta (e.g., 50S, 100S), Yanmar, and others. A built-in safety system adds reliability in demanding conditions.

Proven Performance

Independent tests confirm a significant +15% increase in efficiency in both forward and reverse compared to other folding propellers. Its optimized blade curvature and unique rotation make it highly effective, even in underpowered conditions. The shape also eliminates the need for a shaft brake on hydraulic gearboxes by preventing unintended unfolding under sail.

Professional Craftsmanship

Constructed from premium Nibral or stainless steel alloys, each Gori propeller is precisely balanced, performance-tested, and individually numbered to ensure traceability and support future servicing. Gori continues to be the trusted choice of leading designers, builders, and regatta professionals around the world.
