Folding Sailboat Propeller

Flexofold develops, manufactures and sells the most efficient folding propellers for sailboats and multihull yachts on the market.
The folding propellers are available as 2-Blade, 3-Blade, and 4-Blade in multiple sizes and pitches. All delivered for both shaft- and sail drive installation. The new DAME awarded 2-Blade Composite Folding Propeller from Flexofold is now available for sail drive installation.


No matter if you need a 2-blade saildrive propeller for cruising or regatta sailing, a powerfull 3-blade propeller or a 4-blade to ensure hasslefree handling of your large yacht – Flexofold got the right propeller for you!

Looking at the profile and cross-section of the shaft propellers by Flexofold, you will see a powerful shape that will drive your boat well, converting more of the horsepower into thrust than any other propeller. Twin-helical gears between the blades insure synchronized opening and folding of the blades and the well designed and slim propeller hub provides a very low drag configuration.

Flexofold propellers Advantages

Lors de l'achat d'une hélice Flexofold, vous rejoindrez un nombre grandissant de propriétaires de bateaux bénéficiant des avantages d'une hélice repliable sous voile.


On a folding propeller, the blades do not stick out while sailing as they do on fixed. You won’t catch lobster or crab pots, fishing lines or debris in the water, a “catch” which ultimately may result in loss of steering ability and accident.


Due to the powerful shape and hydrodynamic design, the Flexofold propellers have superior forward, stopping and reversing power. In one test, a 63 foot Hanse went from 8 knots ahead to dead-in-the-water in one boat length! Who said a folding propeller can’t back up? They haven’t tried a Flexofold!


A folding propeller almost eliminates the huge drag from a fixed propeller and improves your sailing performance by 15% on average.  Nothing you do to your boat will increase sailing performance more! It simply makes sailing more enjoyable. You can sail faster than the guy who used to pass you, and keep sailing in lighter air than ever before. Enjoy your sailboat at higher speed.


You probably recognize the situation? Perfect weather and the sails set - and then the noise from a turning fixed propeller! With a Flexofold folding propeller, the noise will be as low as the drag.
Unlike other propeller brands, Flexofold also has strong built-in shock absorbers for quiet opening.


On a Flexofold propeller, the only moving parts are the blades. Smooth acting gears and strong materials secure long durability without need of messy greasing, rebuilding or other maintenance required. Get a Flexofold propeller and spend your time sailing – for many years to come.

Questions - Answers


The question of available space and tip clearance is a bit complex, and requires some additional information, and ultimately a judgment call.
Minimal tip clearance has little effect on performance of a propeller.
The real reason for tip clearance is to reduce noise and vibration created when the vortices coming off the blade tip reach the hull.
Due to the shape & efficiency of Flexofold blades, we have lower tip vortices than any other low drag propeller to begin with.

There are 3 factors that come into play in deciding how much tip clearance to leave:

  1. What is the hull shape? A flat hull above the prop will create more resonance (like a drum skin), while a V-shape or rounded hull form will reflect more of the tip vortices
  2. What is the hull construction? A modern, light laminate will resonate more than an older, heavier laminate. A cored hull may increase or decrease resonance, depending on the core material.
  3. How tolerant are the boat owners of noise and vibration under power? If you’re used to a relatively vibration prone 1 or 2 cylinder diesel, you may not notice the noise created by low tip clearance.

Yes, but you have to use locking screws with pre-applied, underwater Loctite (supplied with all Flexofold propellers). The normal Loctite, which can be purchased in a hardware store, will not cure underwater. And, once a screw with the pre-applied Loctite has been used, it will not work a second time underwater. New screws, with the pre-applied underwater Loctite, are available from Flexofold.

Oui, sans problème. Un jeu de nouvelles pales peut être fourni avec le diamètre et pas adapté à votre nouvelle motorisation. Dans tous les cas votre moyeu doit être équipé d’absorbeur de choque (envoyez nous une photo en cas de doute).

The pitch can be changed by mounting new blades with different size/pitch in the existing hub. Unless you have a very old propeller

Yes. Bronze and stainless steel are very close in the galvanic series and will corrode only very slowly in the absence of an anode. With a properly installed anode on the shaft, you should be protected against any slight galvanic corrosion that might exist.
