A great all-round propeller with a host of unique features The 2-blade Gori Folding Propeller is designed for sailing yachts fitted with engines up to approximately 60 HP (44 KW). The geared blade design ensures blades open and close together giving less vibration ahead and astern. Under sail blades close simultaneously. It is available in 7 diameters from 11.5" to 18" for shaft installation and Sail-drive. RH and LH rotation. Why Not An Extra Knot? Under sail, a fixed propeller slows a yacht much more than most people would imagine. Tests have shown that the 2-blade Gori Folding Propeller can reduce the yacht's total drag by up to 35% - one full knot of extra speed under sail. A folding propeller as opposed to a feathering propeller does not snag seaweed, lobster lines or plastic bags when sailing. Full Power Ahead & Reverse The Gori Propeller gives you the optimum thrust in reverse by virtue of its precision engineered blade shape and profile and does not rely solely on the centrifugal force to open the blades as do many other folding propeller types. Tests have shown that the efficiency of the 2-blade Gori Propeller in forward is better than most 2- and 3- blade feathering and folding propellers. In reverse, tests have shown that the efficiency of the 2-blade Gori Propeller is equal to or better than most 2- or 3-bladed fixed, feathering, and folding propellers. Compatible with all major Sail-Drives The hub of the Sail-drive propeller is manufactured with a flexible bushing that absorbs shock and electrically insulates the propeller from the Sail-drive leg, as required by the engine manufacturers.
