Sailboat propeller

The 3-blade Gori folding propeller marks a technological and functional leap forward in the development of propellers for sailboats. It is now possible for sailboats and motorsailers to gain the folding propeller's speed advantages under sail, combined with the fixed propeller's thrust capability when motoring. The 3-blade Gori folding propeller was introduced on the market in 1994 and won the DAME award and HISWA award the same year, as the best new marine product. "OVERDRIVE" FUNCTION The 3-blade Gori folding propeller's "overdrive" function adds a new dimension to sailing under power. The helmsman can choose the propeller pitch and profile in the water while sailing forward, by regulating the yacht's shift and throttle control. Without the use of vulnerable hydraulics or complicated mechanical devices. The "overdrive" is used when motorsailing in fair weather or when using the engine under sail. The "overdrive" gives the same speed at lower rpms. The result is less engine noise, less vibration and better fuel economy. The function is simple. E.g. when changing from "overdrive" to normal ahead the shift and throttle control is set in neutral, which allows the propeller to fold. Then the shift and throttle control is set in forward again. The propeller in itself adds a new dimension to sailing under power. Qualities that are unique to the 3-blade Gori folding propeller. FULL SPEED UNDER SAIL Folding propellers have been reserved for small and medium size sailboats with moderate engine power. They have been able to obtain under sail the extra speed the folding propeller allows by the minimum drag.
