Gori Propeller 15x9x3RHx1:10W25 - Folding Propeller 15x9x3RH for 25mm ISO shaft
The Gori 3-blade folding propeller, introduced in 1994 and honored with the DAME Award and HISWA Award, signifies a groundbreaking leap in marine propulsion. Engineered for sailing yachts, this propeller's technological advance enables both larger sailing yachts and motor sailers to experience the speed benefits under sail coupled with the thrust of a fixed propeller under motor.
The wing curvature of the 3-blade Gori folding propeller delivers outstanding thrust in both forward and reverse, surpassing most other propellers and enhancing maneuvering properties. Its innovative "Overdrive" function introduces a new dimension to motorized driving, allowing the helmsman to dynamically change pitch and profile when moving forward, seamlessly controlled via the boat's single lever shift without delicate hydraulics or complicated 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, less vibration, and improved fuel consumption. The operation is straightforward, shifting from normal ahead to "overdrive" via reverse, moving the ship clearly backward, then shifting back to ahead. Returning from "overdrive" to normal ahead involves shifting gears to neutral, propeller folds, 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 away from the previous limitations for smaller vessels, the Gori folding propeller is now available for engines over 300 hp, extending its benefits to large sailing yachts and motor sailers. The special design minimizes noise and vibration, common issues with rotary blade propellers featuring flat blades.
The 3-blade Gori folding propeller offers diameters from 15” to 30” for standard shafting and 15” to 20” for saildrive configurations, providing versatility for various vessel requirements. Its low profile when folded minimizes drag, as proven by independent tests, leading to increased boat speed under sail. The unique shape prevents debris entanglement and eliminates the need for an expensive shaft brake in vessels with hydraulic gearboxes.
Advantage under sail
The low profile when folded results in the lowest drag among 3-blade folding and rotary blade propellers, as proven by independent tests. This leads to increased 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. For vessels with hydraulic gearboxes, the Gori propeller eliminates the need for an expensive shaft brake, ensuring durability without compromise.
Performance under engine
Tests by leading yachting magazines and independent organizations confirm the 3rd flg. Gori folding propeller's significantly higher efficiency in both advance (+15%) and reverse (+15%) compared to other folding or rotary blade propellers. This high level of efficiency is attributed to the special curvature and rotation of the propeller blades, optimizing under-powered thrust not achieved with flat-blade designs of rotary blade propellers.
