Product information "VARIPROP 4-blade feathering propeller "
For cruising and high-sailing boats with an output of over 100 kW
Sailing without brakes - when the engine is switched off, the blades automatically turn to the sailing position due to the water current. This results in minimal drag and, depending on wind conditions, 15% to 20% higher speed. No propeller turbulence!
When switching to reverse, a short turn of the shaft turns the leading edge of the blades by 180° and has a higher efficiency than all fixed pitch propellers - in reverse as well as in forward.
Advantages of a VARIPROP rotary blade propeller:
- Lowest drag
Very robust with strong gearing
SoftStopTM shock absorber
External variable pitch adjustment
Shortest hub - ideal for small wells
Each Variprop is manufactured to measure
Dynamically machine balanced - smoother, quieter movement and absolutely vibration-free
Simple installation like a fixed pitch propeller on the shaft
Made in Germany from high-strength Nibral bronze - extremely durable
DNV-GL type approval
Final certification by three-dimensional measuring instrument (MRI) with test certificate
Available for shaft system and saildrive (up to GP-128)
GP as in Grand Performance: Or as in Gawn Profile - the GP series is a further development of the previous world-renowned VARIPROP types and is designed for maximum performance.
