MIO designs and produces controllable pitch propeller from best materials which are resistant to corrosion and have high strength, and they contain a hob with blades which are installed separately and therefore it is possible that they rotate and change their pitches. Adjustment of propeller’s position lead to pitch change and this will create different thrust without changing the propeller rotation speed. This feature brings about below advantage for the vessel: High maneuverability (especially in low speed) Wide range of produced thrust and operating conditions Using one speed and one directional gearbox Reduction of fuel consumption
