Gori Propeller 11.5X8x2RHS-50S - 2-wing Folding Propeller

The Gori Propeller 11.5X8x2RHS-50S, a 2-wing folding propeller, represents over 25 years of continuous evolution since its initial production. Innovatively designed to leverage modern manufacturing technology and testing capabilities, this propeller is engineered for sailing yachts with engines up to approximately 44 kW/60 hp.

Available in seven sizes ranging from 11.5” to 18” in diameter, suitable for both shafts and sail drives, the propeller offers versatility with options for clockwise or counter-clockwise versions. The wing shape, featuring toothing, ensures synchronous wing movement, minimizing vibrations during forward and reverse motion, resulting in optimal pitch setting and efficient conduction under motor power. When sailing, the wings automatically fold to reduce drag to a minimum.

Full Speed When Sailing

Unlike fixed-pitch propellers that create significant water resistance when sailing, independent tests demonstrate that the 2-blade Gori folding propeller can reduce a yacht's water resistance by up to 35%, leading to a notable speed increase of up to 1 knot under sail. The propeller's unique shape prevents entanglement with seaweed, plastic bags, and debris during sailing.

Full Power in Reverse

Extensive testing reveals that the efficiency of the 2-blade Gori folding propeller equals or surpasses that of many 2- and 3-blade rotary or folding propellers, providing optimal reverse thrust through a combination of shape and profile design along with centrifugal force. Unlike most other folding propellers, the Gori folding propeller utilizes both shape and centrifugal force for wing opening.

Full Power When Driving Forward

Independent tests also highlight the exceptional efficiency of the 2-blade Gori folding propeller in forward propulsion, surpassing the performance of numerous 2- and 3-blade rotary and folding propellers.

Saildrive Propeller

The hub of the Gori Saildrive Propeller incorporates a flexible core for shock absorption and electrical isolation, meeting the requirements of engine manufacturers. With a safety system enhancing durability and ensuring maneuverability, this propeller is designed for common sail drives such as Bukh, Sonic, Volvo-Penta (including 50S and 100S drives), Yanmar, and others.
