Why is a feathering propeller a priority?

No other purchase will enhance the performance of the boat as dramatically and for as long as will a feathering propeller


Firstly:
To enjoy faster sailing by practically eliminating drag.
When the engine is turned off, the waterflow automatically rotates the blades into the feathered position. Drag almost vanishes and sailing speed increases by 15% to 20% depending on wind conditions. On longer trips you gain hours, even weeks or more. A further advantage is the elimination of propeller turbulence for a much enhanced rudder effect.

Secondly: To increase stopping power dramatically for stress free maneuvering and docking. When shifting into reverse, the leading blade edges turn 180 degrees. Reverse thrust is then equal to forward, 30% to 40% higher than with any fixed blade standard and most folding props. You can stop the boat on the proverbial dime, typically in less than a boat length.

But in addition, the VARIPROFILE offers much more to make it an unsurpassed value:

  • Hi-Tec blades with GAWN profile to optimize thrust and efficiency while running much more quietly than others
  • Exceptional sailing characteristics through slim shape, light weight and GAWN profiled Hi-Tec blades
  • Separate external pitch adjustments for forward and reverse to optimize engine performance and eliminate propwalk in reverse. Continuously variable fine tuning much superior to large minimum steps of others
  • Robust construction with enclosed helical gearing, QPQ liquid nitriding for long life
  • Interchangeable hub. For repowering just change the blade assembly
  • Fast and easy installation for the average sailor
  • Made out of Hi-Tensile NIBRAL-BRONZE (Ice-Class)
  • Available in 2-blade and 3-blade version for engines up to 75 hp
  • CNC Machining for highest precision
