A new generation of feathering and folding propellers for sailing yachts.

Variprop

User-friendly superior feathering propeller. The VARIPROP blades automatically balance themselves into the position with the least drag creating optimal sailing characteristics for your yacht.

VARIPROP GP 2-blade for small sailing yachts with an engine power of 6-40kW / 8-30HP.

VARIPROP GP 3-blade for cruising yachts with an engine power of 6-100kW / 8-140 HP.

VARIPROP GP 4-blade for offshore vessels.

VARIPROP GP 5-blade pure power and precise handling.

VARIPROP XLS for tall ships and superyachts – any engine power.

SPW is the only manufacturer of feathering propellers in the world to offer this model for a maximum engine output of up to 550kW/750HP. The Variprop XLS is available up to a size of 62″ (almost 1.6m in diameter). The XLS model was designed for tall ships and super yachts that do not have a controllable pitch propeller system installed. It can be easily mounted on conventional shafts.

Unique features:

– Independently adjustable external pitch control. Forward and reverse pitches can be changed in just a few seconds – even underwater.

– Integrated shock absorber (patented) build into the VARIPROR XLS hub.

– German precision engineering, robustness and long life.

– Comes fully assembled, ready to be mounted on the shaft.
