For years, owners of sailboats equipped with folding-blade propellers have suffered from a multitude of seemingly unresolved problems. High noise levels, vibrations and poor performance in reverse have tarnished the enthusiasm of these owners.
Today, with a range of 3 models to suit all yacht sizes
yacht sizes, they can take full advantage of the benefits that VARIFOLD can bring them.
VARIFOLD has been designed to solve the problems that have plagued feathering propellers since their inception. SPW GmbH, with 20 years' experience in the design of VARIPROFILE and VARIPROP feathering propellers, conceived and developed the VARIFOLD range in 2000.
The VARIFOLD range is quite revolutionary in its design, combining the advantages of fixed motor-driven propellers with those of low-drag sailing propellers.
Unlike a duckbill propeller, the opening of the VARIFOLD folding propeller is ensured by both the hydrodynamic force of the blade profile and the force of inertia due to their mass and the eccentricity of their center of gravity. No other manufacturer offers all these advantages on such a wide range of folding-blade propellers.
Technical considerations aside, it's simple: the VARIFOLD does the job perfectly!
