The Varifold 4-blade folding sailboat propeller is the latest Varifold development offering improved performance while maintaining on-board comfort through proven noise and vibration reduction. As with the 2 blade folding propeller and the 3 blade folding propeller, the outstanding feature of the 4 blade design is it’s airfoil shaped sections and modern cambered design. This special blade shape not only lends the Varifold exceptional visual appeal, but also unparalleled thrust and low levels of propeller borne noise. This is important for larger sailboat propellers as once the boat size increases the design an build quality of a propeller has a significant effect on its performance both in terms of fuel consumption and noise.
