SPW is a German familiar company, founded in 1988, manufacturer of feathering and folding propellers. SPW produces the Variprop and Varifold propellers that are designed to improve the performance of the boat. Each propeller is studied individually according to the type of boat and the use to ensure the maximum efficiency.

Variprop GP propellers allow for up to 10% higher performance, available in 2, 3 and 4 blades which balance themselves while the boat is sailing. Varifold propellers combine the benefits of a fixed propeller with those of a low resistance folding propeller when sailing. They are available in 2, 3 and 4 blades and are characterized by low levels of noise and vibrations.
