The Gori Propeller 15x11x3RHx1:10W25, introduced in 1994 and celebrated with the DAME Award and HISWA Award, represents a cutting-edge solution in marine propulsion technology. Designed for sailing yachts and motor sailers, this 3-blade folding propeller offers a unique combination of speed advantages under sail and the thrust of a fixed propeller under motor. With its distinctive wing curvature, it excels in providing excellent thrust both forward and backward, setting it apart in maneuvering capabilities. The innovative "Overdrive" function allows dynamic pitch and profile adjustments during forward motion, enhancing motorized driving without the need for complex mechanics. Suitable for engines ranging from 10hp to 300hp, it breaks tradition by extending its benefits to larger vessels. The propeller's special design minimizes noise and vibration, addressing common issues associated with other propellers. With diameters from 15” to 30” for standard shafting and 15” to 20” for saildrive configurations, the Gori folding propeller offers the lowest drag, proven by independent tests, resulting in increased boat speed under sail. Its unique shape prevents debris entanglement and ensures the propeller remains closed when sailing, eliminating the need for an expensive shaft brake in vessels with hydraulic gearboxes. Tests by leading yachting magazines confirm its significantly higher efficiency in both advance and reverse compared to other propellers, attributed to the special curvature and rotation of the propeller blades, optimizing under-powered thrust often compromised in flat-blade designs. The Gori Propeller 15x11x3RHx1:10W25 stands as a versatile, efficient, and advanced choice for enhancing sailing and motorized experiences on the water.

Gori Propeller 15x11x3RHx1:10W25 - Folding Propeller 15x11x3RH for 25mm ISO shaft

The Gori 3-blade folding propeller, introduced in 1994 and honored with the DAME Award and HISWA Award, represents a significant leap in propeller technology for sailing yachts. Its innovative design caters to both larger sailing yachts and motor sailers, offering the dual benefits of speed advantages under sail and the thrust of a fixed propeller under motor.

The wing curvature of the 3-blade Gori folding propeller ensures exceptional thrust in both forward and reverse, providing superior maneuvering properties compared to most other propellers. A standout feature is the "Overdrive" function, allowing the helmsman to dynamically adjust pitch and profile during forward motion, controlled effortlessly through the boat's single lever shift without the need for delicate hydraulics or complex mechanics.

Utilized under power in calm weather or when powering under sail, the "Overdrive" function maintains the same speed at lower revs, resulting in reduced engine noise, vibration, and fuel consumption. Its operation involves a simple shift from normal ahead to "overdrive" via reverse, followed by a shift back to ahead. Returning from "overdrive" to normal ahead requires shifting gears to neutral, propeller folding, and shifting back to ahead, setting the Gori folding propeller apart from others in the market.

Suitable for engines from 7kW (10hp) - 221kW (300hp)

Breaking convention, the Gori folding propeller is now available for engines over 300 hp, expanding its benefits to large sailing yachts and motor sailers. The result of its special design is a reduction in noise and vibration, addressing common issues associated with rotary blade propellers with flat blades.

Available in diameters from 15” to 30” for standard shafting and 15” to 20” for saildrive configurations, the Gori 3-blade folding propeller excels in providing the lowest drag, proven by independent tests. This translates to an increase in boat speed under sail, enhancing the overall value of your vessel. The unique shape prevents debris entanglement and ensures the propeller remains closed when sailing, eliminating the need for an expensive shaft brake in vessels with hydraulic gearboxes.

Performance under engine

Tests conducted by leading yachting magazines and independent organizations affirm the Gori folding propeller's significantly higher efficiency in both advance (+15%) and reverse (+15%) compared to other folding or rotary blade propellers. This efficiency is attributed to the special curvature and rotation of the propeller blades, optimizing under-powered thrust that is often compromised in flat-blade designs of rotary blade propellers.
