Sailboat propeller / 4-blade / folding
VARIFOLD SPW

the VARIFOLD 4-blade propeller with a diameter of up to 920mm is the latest SPW development. 4 strengths for on-board comfort which fulfil a modern skipper's every desire. Just as with the 2 and 3-blade series, the outstanding feature of the blades is their modern cambered design. This special blade shape not only lends the VARIFOLD exceptional visual appeal, but also unparalleled thrusts!

The propeller was designed and developed to the production stage in close collaboration between Bruntons Propellers and SPW GmbH, SPW having conceived the design and Bruntons taking on construction. The end-product is a 4-blade propeller that delivers greatly increased top speed under sail and much smoother running when powered.
