VARIPRROFILE  — Designed to meet highest quality standards
The new VARIPROFILE is the perfect feathering propeller for boats and yachts with engines up to 75 hp. Thanks to innovative mass production methods and construction we are able to offer the VARIPROFILE as an unbeatable value, while still conforming to our highest quality standards.

The GAWN blade profile results in optimized thrust and quiet running, plus outstanding hydro-dynamics. It is made out of NIBRAL-BRONZE (Ice-Class) employing latest CNC technics.

GAWN blade Profile

The Variprofile blades incorporate the GAWN/KALAN profile. This means greater efficiency and quieter running with less fuel consumption

The VARIPROFILE is a unique feathering propeller, the first sailing propeller to incoporate the Hi-Tec GAWN/KAPLAN profile in it’s blade design

This profil is mainly used in high performance fixed props for power boats, rudder profiles and in the aircraft industry.

Less fuel consumption

The VARIPROFILE offers exceptionally low fuel consumption.
The VARIPROFILE, with optimal pitch adjustment, not only provides more thrust in forward and reverse than other propellers, but amazingly also uses less fuel doing so. Yanmar-France tested the fuel consumption of a 3-blade VARIPROFILE with a 3-blade ZF standard fixed prop, both on the same Jeanneau SUN ODYSSEY 30i.
Der Variprofile zeichnet sich u.A. durch einen sehr geringen Verbrauch aus.


The astounding results: Average fuel consumption with the fixed prop was 0.48 liter p. nautical mile vs. O.32 liter with the VARIPROFILE, a reduction OF 33 %. YET THE SPEED AT THE SAME RPM WAS AN AVERAGE 7% HIGHER, yielding the best of both worlds: Higher speed and substantially less fuel consumption.

 

Less drag

Drag of the VARIPROFILE compared to a folding - and fixed propeller.

Tests have shown that the drag under sail is reduced to the vanishing point. The graphics show the results for 2- and 3-blade propeller, VARIPROFILE in comparison to a folding propeller and a fixed propeller.

Better Hydro-Dynamics

Graphic stream display at 5 knots
Thanks to the slim profile of he VARIPROFILE hydro-dynamics under sail are excellent.

How well the VARIPROFILE fared is impressively shown in the tests.
