EWOL at the Annapolis boat show: high-tech propellers and the new EnergyMatic on display
EWOL sailboat propellers are made of stainless steel super-alloys assuring the highest mechanical and corrosion resistance. Under sail blades feather to reduce drag, while micrometric pitch-setting allow to optimize thrust to lower RPM with consequent fuel savings. Blades flip 180° giving exceptional thrust and reduced prop walk while docking Dynamic balancing and a central pinion for blades synchronization kill vibrations.
