Made in Germany

Probably the finest feathering propeller in the world


  • Robust, long lasting gearing
  • SOFTSTOP™ shock absorber
  • Shortest Hub — perfekt for smaller prop apertures
  • Available as 2-, 3- or 4-Blade Version
  • For engines from 12 to 750 HP
  • All VARIPROP are made out of high-strength NIBRAL-bronze (ice-class) for extra long life
  • MRI testet for highest quality

Short overview:

The idea was to develop a superior feathering propeller that was user-friendly. That was more than 30 years ago and we are pleased to say we have achieved all our design ambitions and more. Through continuous innovation and rigorous testing SPW has designed and developed the VARIPROP to be the most modern feathering propeller found anywhere in the world.

Which VARIPROP is the right for your engine:

The VARIPROP 2-Blade

for small yachts with engines from 6 to 40 hp

The VARIPROP 3-Blade

for all sailing vessels with engines from 6 to 100 hp

The Variprop "Blue Water" 4-Blade

For open sea vessels with engines above 100 hp

Der Variprop XLS 4-Blade

For tall ships and Superyachts any engine power

A look at our VARIPROP feathering propellor. It reduces drag under sail but still produces full power when motoring. Since it is a 4 bladed prop it produces the most thrust in the aperture we have between the skeg and the hull of our Southerly 42.

VARIPROP features


Factory-ready delivery

  We supply the VARIPROP feathering propeller at the factory

  •      assembling
  •      ready for install
  •      balanced
  •      greased
  •      pitch is set

When the engine is turned off, the waterflow rotates the blades automatically into the feathered position.

Benefits: Drag is almost eliminated and speed increases 15% to 20%, depending on wind conditions. Propeller turbulence vanishes and a substantially enhanced rudder effect is achieved.

When shifting into reverse, less than one shaft rotation turns the leading edge of the blades 180 degrees.

Benefits: Efficiency (thrust) in reverse is equal to forward, 30% - 40% more than all fixed propellers. You get improved stopping power; however, this also increases “Prop Walk” (paddle wheel effect). In case of varying step-down gears (i.e. Yanmar Shafts) the pitches in foward and reverse are optimal set by factory.

Independently adjustable external pitch control

Forward and reverse pitches can be changed in just seconds — even underwater

Benefits: Custom fine tuning (in micrometer-small increments) of reverse thrust vs. prop-walk. (For most owners, eliminating prop walk is more important than maximizing reverse thrust.)

VARIPROP allows you to customize that balance for optimum control, maneuverability and safety. Independent fine tuning of forward thrust means that VARIPROP delivers the best possible performance (speed, thrust, fuel economy) in forward without compromising reverse performance – and vice versa.

SoftStop™ shock absorber

Shock Absorbing Multidisc Brake (patented) built into the VARIPROP hub.

Benefits: Dramatically reduces shock loads on gearbox and drivetrain, permits shifting at higher speeds without damage, preserves preset pitches by eliminating hard limit stop impacts (the typical “clunks” of all others). The entire drive train benefits: longer cutless bearing life, minimized wear on gearbox, clutch plate, bearings.

Shortest hub

VARIPROP’s hub is flush with the forward edges of the blades, and barely protrudes past the aft edges.

Benefits: VARIPROP will fit into the smaller prop apertures of older traditional “full keel“ yachts – not possible with most competing propellers. Line cutters – SPURS or solid types – can be mounted very close to the VARIPROP blades, the ideal position. This is a huge advantage for boats operating in areas with fields of lobster pots, crab pots and fish traps. With competing props, because of their much longer hubs, all such cutters must be mounted farther away from the prop blades, which drastically reduces their effectiveness.

Precision engineering

Superb German precision engineering in a custom made prop vs. mass-produced competitors.

Benefits: Every VARIPROP is built to order-consistently 100% up to stringent specs for reliable, smooth and efficient operation. Quality is assured by compliance with DIN EN ISO 9001 international manufacturing standards and approved according to the standards of the “Germanischer Lloyd”.

Balanced by machine

Each propeller is dynamically balanced by machine — the result: hightest quality.

Benefits: Smoother, quieter running with absolutely zero vibration

MRI tested

As a final step all propellers are tested by an Hale MRI (Measurement Recording Instrument), one of the most modern 3D Measurement Instruments.

Benefits: Thanks to the 3D propeller analysis you can be sure that each VARIPROP is maximum quality and precision proofed before shipment. Each customer gets an individual test certificate when the VARIPROP will

Comes fully assembled and tested

Benefits: VARIPROP mounts on your shaft just like a solid prop. No disassembly, no shaft modifications.


VARIPROP Models


The VARIPROP 2-Blade

The VARIPROP 2-blade (DF 80 and DF 107) is the standard propeller for smaller sailing yachts with an output of 6 – 40 kW. The 2-blade is ideal for such sailing yachts since it has very high efficiency under power, as well as very low drag, as it only has 2 blades.

The VARIPROP 2-blade's manoeuvrability is equally outstanding, since in reverse gear each blade self-adjusts to the optimum pitch.

The VARIPROP 2-blade is ideal for racing and cruising.

The VARIPROP 3-Blade

The VARIPROP 3-blade is the original standard propeller for sailing vessels with an output of 6 – 100 kW. It delivers very smooth running, equally good stability especially at sea under power, and very low drag. Just like the VARIPROP 2-blade, the 3-blade has outstanding manoeuvrability, since in reverse each blade self-adjusts to the optimum pitch.

The VARIPROP 3-blade is the ideal propeller for cruising yachts. In exceptional cases or higher loads and we recommend our VARIPROP "Blue Water" (4-blade).

4-Blade-Power — the VARIPROP „Blue Water“

Especially in blue water conditions, excessive blade loading causes cavitational noises, bubbles on blades and resulting loss of power, just when you need it most in the trough.

The solution is the VARIPROP 4-Blade — to-date worlds most modern 4-blade feathering propeller, with 30% larger blade areas, less blade loading, much greater thrust and undiminished power.

A smaller diameter fits where others cannot. Fit a 4 blade VARIPROP. The cost is less than you might think. The results are simply amazing. Smooth running, tremendous power under all conditions, no vibration.

The VARIPROP XLS

Special needs require special solutions: the VARIPROP XLS is probably the best automatic feathering propeller for tall ships and superyachts.
