Flexofold Propellers
Except for those prefabricated propellers which Henley’s distribute, a detailed propeller drawing is provided to our customers in order to give the man idea on what will be the profile of their custom made propeller. Henley’s will specify one of these custom designs to suit your vessel.
Why should you choose Henley’s Propellers?
Data used for prop selection is supplied by our customer on a Propeller Specification Form. This information is firstly compared to Henley’s vast database of proven designs, and then entered into intricate computer software programmes insuring the best possible selection for the customer.
​
We then use this propeller selection in a Propeller Drawing Program which is a parametric design/drafting tool for the preparation of detailed and dimensioned propeller drawings. The designs made with the use of this equipment are then transformed into patterns, castings and a personalised “custom built” boat propeller. To ensure the propeller design is maintained and that the propeller is manufactured in conformity with ISO 484/2 Class 2, 1 or S standards, Henley’s have invested 20 years ago in Electronic Propeller Scanning equipment.
This allows us to measure a propeller and to produce reports on the quality of the propeller to a set standard that is recognised World-wide.
This technology also allow us to repair our props to the original design and or repair props of various designers to a known standard of tolerance which produces the best efficiency’s. This gives Henley’s a distinctive advantage over others, as we are able to control the design, manufacture and the after care of Henley’s propellers.
Henley’s is also involved in a worldwide network of propeller technicians operating similar equipment, to whom we will be able to forward your propeller data and they would be able to extend the Henley’s care you deserve.
Tiger Propellers
The Tiger propeller is the most POPULAR type of bronze propeller that Henley’s supply.
​
The concept is linked to US Submarine Propeller Design. Its highly skewed profile gives exceptional smoothness and maneuverability especially in reverse, in comparison to more traditional style propellers. During trials, this type of propeller was found to perform better in the mid and top speed range of the vessels tested. Large savings in fuel consumption have also been well documented from various commercial and pleasure craft users. Manufactured in 3, 4, 5 & 6 blades, sizes from 17″ to 45″ and built to ISO484/2 Class 1 or S standards.

Flexofold 2-Blade Saildrive Composite Folding Propeller
The NEW generation of folding propellers
Taking advantage of modern composite materials, the Flexofold Composite propeller 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.
Nomminated and awarded a “Special mentioning” at the prestrigious DAME Award 2016 (Design Award Marine Equipment, METS trade show in Amsterdam, Holland).
Special features
-
Composite material immune to electrolysis *)
-
Light weight (2,8 kgs less a standard folding propeller)
-
Helical gearing between the blades ensures a syncronized folding mechanism
-
Patented mounting system absorbs impact from the centrifugal force and allows adjustment of play in gears
-
Protective cover over the gearing
-
Easy replacable build-in anodes in each blade
-
Dual shock absorbers for quitet opening of the propeller
-
Special innerhub to protect the saildrive and gearbox from the propeller impact
-
Mounting screws are pre-applied with Loctite for mounting above as well as under water
-
Water lubricated - no need for maintenance
Special features
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.
​
To be fittet on Selva saildrives when using an adpater.
