A wide range of feathering propellers
The German manufacturer SPW is a specialist in the manufacture of propellers for recreational boats. Its complete range covers all models: 2 to 5 blades, fixed, folding or feathered.
The Variprop range, developed for sailboats, is available with 2, 3 or 4 blades. It is equipped with an automatic feathering mechanism when sailing under sail. With standard diameters ranging from 12 to 32 inches, or 305 to 813 mm, Variprop propellers cover the needs of a wide range of recreational boats. Sizes larger than 50 inches are available on request.
Hydrodynamic efficiency forward and backward
Variprop propellers offer a significant hydrodynamic gain compared to fixed or folding blade models. With the propeller feathered, the manufacturer announces an acceleration of the boat of 15 to 20% depending on wind conditions, thanks to the reduction of drag. Once the engine is engaged, reversing the blades 180° in reverse allows the same efficiency as forward, increasing the boat's manoeuvrability and safety.
Easy maintenance and installation
Variprop propellers are delivered pre-assembled. The pitch was preset at the factory at the time of ordering according to the characteristics of the boat and motor. The installer can easily mount the propeller in a limited number of operations.
If necessary, the pitch of the propellers can be modified afloat, without disassembly, by a diver. The adjustment is made by means of a screw accessible in the propeller hub.
A patented shock absorbing system is integrated in the hub for durability. It eliminates the jolts associated with sudden changes in pace, increasing the life of the entire propulsion line.
An attractive option for his sailboat
Distributed in France by Fenwick, the standard Variprop propellers are available from stock. Specific requests are available within 3 to 4 days. Only 10% more expensive than a folding propeller, the feathered propeller, which is acclaimed as a retrofit, is enough to seduce.
