SPW GmbH creates a low-drag propeller with greater effi ciency than a fi xed propeller.

Bremerhaven, Germany | SPW GmbH, the world’s leading sailing propeller specialists, have announced the production of the first feathering propeller that offers the effi ciency found in a helically twisted fixed or folding propeller.

VariProfile combines very low drag with very high efficiency and full adjustability of both forward and reverse pitch. Dragging a fixed propeller through the water is now a thing of the past.

The engineering team at SPW has spent over two years in research and testing to create a feathering propeller that will exceed all performance standards for feathering and folding propellers while maintaining the outstanding quality for which SPW propellers are renowned.

The key to the VariProfile success is the, fi rst ever, mating of the Gawn/ Kaplan blade profile to a sailboat propeller. The achieved efficiency meets that of the best twisted blade folding propellers as tested at the Naval Testing Institute of Potsdam. The result is a propeller that gives superb motoring performance coupled with extremely low drag under sail and easily adjusted forward and reverse pitches. All of these features at a price point lower than most other feathering propellers on the market.
