Variprop Feathering Propeller
New Hi-Tec Feathering Sailboat Propeller Trumps Fixed Props
SPW G.m.b.H, sailing propeller specialists in Germany, have announced the production of their new VariProfile feathering propeller offering greater efficiency than a twisted standard fixed prop, combined with lower drag than a folding propeller. The full pitch adjustability forward and reverse of the proven big brother VariProp have been maintained. Actual one-on-one comparison tests with a 3-blade fixed prop have shown the VariProfile to be 7% faster with 35% less fuel consumption at the same rpm; a real "Green Bio" Prop. Dragging a fixed propeller through the water is now a thing of the past!
