2-Blade Saildrive Composite Folding Propeller

The NEW generation of folding propellers

Taking advantage of modern composite materials, the Flexofold Composite propeller hub is not only immune to electrolysis, it also features a protective torsional hub, low weight and high strength – all combined in an attractive design.
​The Flexofold Composite propeller still provides the recognized low drag, higher speed and good performance under sail, as well as high thrust and strong maneuverability under power.

The NEW Flexofold Composite propeller has been tested for more seasons by appointed test sailors and already chosen as original propeller by more boat yards, including Elan Yachts and Saffier Yachts.

Nominated and awarded a "Special mentioning" at the prestigious DAME Award 2016 (Design Award Marine Equipment, METS trade show in Amsterdam, Holland).

Hub immune to electrolysis

A common issue for sailboat owners is electrolysis – coursed by electrical errors in the sailboat or shore power.

Today’s use of electrical equipment on sailboats increases the risk of wrong installations. Even if all installations are ok, docking in a marina with defective shore power can cause severe damage. This, as stray current easily damages the propeller – normally being the part with the best electrical connection into the water.

Our determination solving this matter has now resulted in the development of a new generation of folding propellers – the 2-blade Flexofold Composite!

Propeller sizes

The 2-blade Composite propeller for saildrive is available in diameters of 15" to 18" - all in a wide range of pitches.

Available for both LEFT and RIGHT turning saildrives (saildrives are generally LEFT turning, however, catamarans might use counter rotating propeller on one side).

Compatible with...

The Flexofold propellers has a 100% fit on all common saildrives from Yanmar, Volvo Penta, Lombardini, Technodrive and Torqeedo Deep Blue.
