Varifold Propellers have taken the market by storm. Regularly fitted by such notable yacht building names as Baltic, Swan, Wally, Moody and Oyster, the complete range of Varifolds has a model for cruiser racing and racing yachts of every size. Varifold is revolutionary in design and brings a revolution to the yachts they are fitted to. Radical reductions in noise and vibration and excellent performance under engine, both ahead and astern, are the result of the propellers unique design. Varifolds have proper helical pitch distribution, including pitch reduction towards the blade tip. This pitch reduction 'unloads' the blade tips and, combined with the skewed blades, greatly reduces noisy pressure pulses against a yachts hull. While some other folding propellers have a helical pitch shape, few have proper sections or pitch distribution. None, put all these requirements into a complete package, except Varifold.
- Diameter 305mm to 432mm or 12" to 17"
- For engines rated to 50hp
- Available for shafts & saildrives
- Blades fold completely together for minimum drag
- Modern blade design with substantial blade area for smooth running and minimum noise & vibration
- Rubber bump stops minimise blade opening impact

By now everybody knows about the function of the folding blades propeller for sailing hulls is:
TO REDUCING THE PROPELLER DRAG DURING SAILING
(propeller drag is reduced about 90% compared to the traditional two fixed blades propeller).
The opening operation is automatic and is caused by the centrifugal force, increasing according to the engine revolution. In forward gear the pressure on the blades allows a performance equal to the fixed-blades propeller.
During this opening phase a quick acceleration of the engine is not advisable, and we recommend to make it
smoothly and gradually.
Even at low revolutions the centrifugal force is enough to opening the blades.
When the engine is off, a forward speed of 1 to 2 knots generates sufficient water pressure for the blades to close.
Reverse gear has always been the main problem for folding blades propellers.
Mainly due to the water pressure acting in opposition to the blades opening and the lack of a support point for the blades on the hub, only partially open, and the blades float, causing an unstable and insecure condition when maneuvering.
In order to avoid this inconvenience we studied and tested special blade sections that allow the blades to remain fully open during reverse operation with positive maneuvering results.
