I installed the EWOL propeller on my boat, a Hallberg Rassy 45 with TMD31D engine. The propeller works very well both as a cruising speed in forward gear and in maneuverability.

Also good is the flag position that allows me to sail quickly and without rotation noise from the propeller

Ho installato l’elica EWOL sulla mia barca, un Hallberg Rassy 45 con motore TMD31D. L’elica funziona molto bene sia come velocità di crociera a marcia avanti che come manovrabilità.

Buona anche la posizione di bandiera che mi permette di andare a vela velocemente e senza rumore di rotazione dall’elica

On my current boat I have installed an EWOL propeller for several years now and I am completely satisfied with it. The propeller is light enough to be well tolerated by my sail drive. In motor maneuvers it transmits safety while sailing “disappears” allowing a perceptible increase in performance. The possibility of micrometric adjustment of the pitch even with the boat in the water and in total autonomy represents an additional added value as it completely eliminates the fear of mistaking the pitch value in the purchase of a new propeller

Sulla mia imbarcazione attuale ho installato una elica EWOL ormai da diversi anni e ne sono completamente soddisfatto. L’elica è leggera al punto da essere ben tollerata dal mio sail drive. Nelle manovre a motore trasmette sicurezza mentre navigando a vela “sparisce” consentendo un incremento percepibile delle prestazioni. La possibilità di regolazione micrometrica del passo anche con barca in acqua e in totale autonomia rappresenta un ulteriore valore aggiunto in quanto elimina completamente la paura di sbagliare il valore del passo nell’acquisto di un’elica nuova

Dear EWOL,

I just wanted to let you know, that the EWOL propeller has been fantastic during PolarQuest2018 to and around Svalbard.
Due to the robust and over-dimensioned 4 blade design, forward performance was as good as the original fixed propeller without increase of fuel consumption (3.2 litres/hour at cruising speed). Gain whilst sailing is significant and produces much less wear and noise. Reverse propulsion is most impressive and a more than useful feature when navigating in uncharted waters, where it is vital to be able to stop at once. Even though 2018 was a record year in lack of ice, we sailed along the ice edge for hours. Due to the ’round’ design of the propeller blades, contact with pieces of ice didn’t harm the propeller. The only improvement needed has been be to reduce the pitch of the blades in forward position allowing to produce more thrust at low speed, especially when beating against strong winds. Well, this has been done easily!

Since I saw the propeller on exhibit, I was confident in the design of EWOL and our experience has been more than positive. Thank you for your support.

Hello, I changed a fixed three-bladed propeller on my Gibsea 126plus, for an EWOL E3 in stainless steel. Installed in May very easily the results are interesting: no more vibrations even at high speed, gain in sail of 1.5 knots, reduction in consumption from 2.6 to 2.1 liters, and the best is impeccable reverse maneuvers. As for the price, it is equivalent to other brands. The big advantage is the micrometric adjustment of the pitch which adapts to the engine speed, when sailing the blades are facing the navigation finished drag.

Bonjour j’ai changé une hélice tripale fixe sur mon Gibsea 126plus, pour une EWOL E3 en inox. Installé au mois de mai très facilement les résultats sont intéressant: plus aucune vibrations même à haut régime, gain à la voile de 1,5 nods, réduction de la consommation de 2,6 à 2,1 litres, et le meilleur c’est les manœuvres de port marche arrière impeccable. Quant au prix c’est équivalent aux autres marques. Le gros avantage est le réglage micrométrique du pas qui s’adapte au régime du moteur, à la voile les pales se mettent face à la navigation fini le traînée.

I am a happy owner of an Ewol propeller purchased in 2009 for my Dufour 485 boat that you see in the picture. The engine is a Volvo Penta 75 turbo with Sail drive.

The propeller immediately proved to be very effective and practically has no evolutionary effect and the adjustment of the step is done with a simple mask by diving for a few seconds. The only precaution is to use an appropriate antifouling.

Sono felice possessore di un elica Ewol acquistata nel 2009 per la mia imbarcazione Dufour 485  che vedete in foto. Il motore è un Volvo Penta 75 turbo con Sail drive.

L’elica si è subito dimostrata molto efficace e praticamente non ha alcun effetto evolutivo  e la regolazione del passo si fa con una semplice maschera immergendosi per pochi secondi. Unica accortezza utilizzare una antivegetativa appropriata.

Hello my friend,

I went for trial run. The prop performance was excellent. I did have to decrease the pitch to 18 degrees to get the recommended rpm.

All is well.
Fair winds,

The choice of the EWOL propeller was made for several reasons: stainless steel construction, easy assembly, micrometric adjustment and sales department with excellent advice. Thanks to Mr. Moroni. The result with the engine in forward gear is, compared to a fixed three-blade propeller, from 200 to 300 rpm less at the same speed. In reverse, here are all the advantages of this propeller: the boat goes where we want it to go. Under the sail, I lock the shaft in reverse gear that otherwise, in neutral, would be creating vortexes in the helm. It is forgotten as the boat gains speed the feathering position helps speed, especially in light air. Gain: between 0.5 and 1 knot depending on the state of the sea.

Le choix de l’hélice EWOL s’est imposé pour plusieurs raisons: sa construction en acier inoxydable, sa facilité de montage, son réglage micrométrique et le service commercial de très bons conseils. Merci à monsieur Moroni. Le résultats en marche avant au moteur est, par rapport à une hélice fixe tripale , est de 200 à 300 tours de moins pour une vitesse égale.En marche arrière, tout l’intérêt est dans cette hélice. Le bateau va là où on veut qu’il aille. Sous voile, je bloque l’hélice en marche arrière sinon elle tourne au point mort créant des remous dans le safran. Elle se fait oublier tout en donnant de la vitesse au bateau car la mise en drapeau favorise la vitesse surtout dans les petits airs pour moi. Gain: entre 0,5 et 1 noeud en fonction de l’état de la mer.

I have an Ericson 35, that previously had a had a 2 bladed 14 inch prop that performed poorly in reverse and in heavy seas. I purchased an EWOL 15 inch prop this past year and installed it this past Spring. Initially the pitch was set too high, but after a couple of in water prop adjustments, the prop has been performing beyond expectations. Sailing speed has increased and reverse performance now exists. Cruising this summer through Woods Hole against 5 knots of current the prop proved it’s worth. The biggest factor that sold me on the EWOL was the ease of pitch adjustment, something that is hard to guess right the first time. I would highly recommend the EWOL feathering prop.

I own the Alibi 54 hi-performance sailing cat DIFFERENCE. She was built in 2010 and came equipped with folding props which had two serious drawbacks: very poor performance in reverse and if allowed to freewheel, which can happen, they had a bad habit of flying open when sailing over 15 knots causing enormous vibration and drag. I would say even dangerous for a boat that can sail well over 20 kts. I recently refitted EWOL E3 to my twin 40 hp Volvos with sail drives. Theses props are awesome! Superior handling and maneuvering, easy feathering, full reverse authority and total quiet when shifting. They’re expensive, but wow, are they great.
