VARIPROP is the flagship feathering propeller that over the past decade has built the most enviable reputation as the finest, most robust, reliable, and best performing propeller of its kind available today.

Some of the benefits of a VARIPROP installation are:

  • Near zero sailing drag
  • Powerful thrust in head seas
  • Incredible control in reverse and maneuvering
  • Custom tailored “prop walk”, increased, reduced or eliminated
  • External and separate fine tuning of forward and reverse pitch for optimal performance
  • Massive gears for decades of reliable and trouble free service
  • “Soft-Stop” *TM Multidisc Brake system to minimize impact when reversing gears
  • 2,3, and 4 blade models in all hub sizes for shaft and saildrive
  • Shortest hub length fits small apertures
  • Delivered fully assembled, balanced, lubricated and individually tested, ready to install on any shaft without disassembly or modifications necessary.

VARIPROFILE  feathering propeller is the latest addition to the VARI-family of fine sailing propellers. It is especially designed for the modern fin keel production yacht. VARIPROFILE propellers are available in 2-blade and 3-blade configurations for engines up to 140 hp. They offer complete fine tuning for forward and reverse pitch.

Building on the proven features of the VARIPROP the most significant  technological advance is the incorporation of the HI-TECH GAWN/KAPLAN blade profile. Normally associated with high-speed power boat and aircraft propeller blades the Gawn/Kaplan blade profile delivers outstanding efficiency with the result that the VARIPROFILE delivers speeds normally associated with fixed propellers or the best folding propellers.

The innovative use of modern high-strength materials (QPQ liquid Nitriding) for the carefully machined helical gears allows a hub of small diameter and a streamlined shape resulting in a very low sailing drag. The VARIPROFILE is unique in that the hub is a separate piece from the blade/gear assembly. With a wide range of pitch adjustment available the blade/gear assemblies can be easily matched to any hub. In the event of a repower or rotation change a new blade/gear assembly can therefore be attached  to the existing hub. 

With all these advancements available at a lower cost, the VARIPROFILE represents a modern example of  MORE FOR LESS !
