IT WORKED PERFECTLY

I was able to do a sea trial with my new propeller, it worked perfectly as advertised.

THE PROPELLER DESIGNED BY EWOL HAS GIVEN AN EXTRAORDINARY THRUST TO MY BOAT

The propeller designed by EWOL gave an extraordinary thrust to my boat. Thank you for the extreme accuracy of the calculations, for the courtesy of the pleasant conversations and for the timing of the supply, a rare occurrence today.
While the new propeller was being assembled for my boat, a Comet 311s, a young sailor approached me and told me: “but this is an Ewol propeller, it’s the best in the world.” I replied: I don’t know if it is the best, but the sea will give its answer “. After a cruise that from the Circeo touched Palmarola, Ponza, Ventotene, Procida, Positano, Amalfi and Salerno Marina d’Arechi, I can say that the performance was extraordinary. With the typical load of cruising with the Ewol propeller, Volvo 20/20 engine, 5.5 knots are reached at 2000 rpm and 6.5 at 2500 rpm, 1100 rpm below the maximum. Greetings,

L’ELICA PROGETTATA DA EWOL HA DATO UNA SPINTA STRAORDINARIA ALLA MIA BARCA
L’elica progettata da EWOL ha dato una spinta straordinaria alla mia barca. Grazie per l’estrema esattezza dei calcoli, per la cortesia delle piacevoli conversazioni e per il tempismo della fornitura, circostanza oggi rara.
Mentre in cantiere veniva montata la nuova elica per la mia barca, un Comet 311s, si è avvicinato un giovane velista che mi ha detto: “ma questa e un’elica Ewol, è la migliore al mondo”. Gli ho risposto: Non so se sia la migliore, ma il mare darà il suo responso”. Dopo una crociera che dal Circeo ha toccato Palmarola, Ponza, Ventotene, Procida, Positano, Amalfi e Salerno Marina d’Arechi, posso dire che il rendimento è stato straordinario. Con il carico tipico della crociera con l’elica Ewol, motore volvo 20/20 si raggiungono i 5,5 nodi a 2000 giri e i 6,5 a2500 giri, 1100 giri sotto il massimo. Grati saluti,

THE PROPELLER HAS BEEN FANTASTIC

My yard fitted the EWOL propeller and we have been using it all August. I wanted to tell you that the propeller has been fantastic. It’s extremely smooth. The power and the pitch as delivered has been a perfect match for our engine where we get good performance in the mid range and still get excellent top speed.
Reversing is a breeze and thrust in reverse is excellent. And of course for the first time we can sail without the prop shaft spinning which is both (a lot) faster and quieter than we had before.
We had the propeller coated with PropSpeed and have had no issues with singing or strange noises.
I think your propeller is excellent and would happily recommend to anybody contemplating a conversion for a motorsailor such as ours where thrust under power is important.
Kind regards,

Working fine

I thought I would drop you a quick email to let you know that I pulled my sailboat, Exeter, out of the water last Friday and had a chance to inspect the propeller after a summer’s worth of sailing in Chicago. Attached are several photos. When the boat first was on the hard, the bottom was covered in a thin slime with no major growth. This is usual for boats in Lake Michigan. After a pressure wash, the propeller looked as shown in photo 1. After a quick, mild acid wash, the propeller looked as shown in photo 2. Looks like brand new! The only interesting thing to report was that my magnesium anode on the propeller shaft was quite severely consumed. I still may be having a stray current issue on the dock. It did its job and there didn’t seem to be any corrosion issues with the propeller.
So, overall, I am very pleased with my Orion propeller. I changed the pitch to be right on 20 degrees and will see how this works out next year. The only thing I would recommend to EWOL would be to also offer the spinner anodes on the propeller to be made out of magnesium. This would double protect the propeller for sailing in fresh water. (note: we have now magnesium anodes available in our shop online)

It is working fine and the performance seems better than the three bladed M… that I replaced. It is smoother when motoring and seems to be a little bit faster when just motoring at idle speed. I still don’t have the pitch set perfectly. At launch, I went with a 18 degree blade setting which is a little bit low. The engine (Yanmar 2GM20F), easily can rev up to 3600 and the boat speed is a little bit over 6 knots. Shortly, I will be setting it to 19 degrees and see how this works.

Marked improvement

Thank you for those valuable recommendations which I will follow carefully. We sailed for about two month with your propeller which works perfectly with a clear improvement of speed at sail and easy maneuvers in harbours. It was in perfect conditions when we took the boat out water.

Best regards

Working perfectly

The propellers are working perfectly, I have excellent experience with them, attached please find 3 pictures taken on the 14th of March 2017.

Even the Rope cutters have been a good decision, they work perfectly !

More than happy

I am more than happy with you product, the propellers have been an excellent combination with the boat and the new Yanmar 4JH80 engines. The new engines are a common rail fuel system which is computer controlled therefore it is very easy to see on the instruments even slight differences. While underway with both engines just idling over if I pull up a sail I can see the fuel consumption drop.

Where you propellers come into their own however is in tight situations like docking while travelling in tight situations , in a new marina where the tide or wind is causing problems. The thrust and instant response is amassing making docking in new places under difficult conditions a piece of cake. On one other occasion I was crossing a coastal bar when I encountered a 3 meter swell in which the boat just handled with ease at lower RPMs. I believe again the thrust engine combination was reason .

There some interesting figures come out of the boats performance by comparison of the “A…prop” and the EWOL prop At 2,500 RPMs. The EWOL props push the boat along at 9.5 knots using 3.5 litres of fuel per side.

With the A…prop although they are 17 inch in diameter the boat for the same RPM 2500 is only doing 8 knots and using 4.7 litres per hour per side.

I find the difference in handling the cat very noticeable especially when trying to position the boat in a busy marina. With the EWOL I have fingertip control at very low RPM but the A…. Prop I have to use lots of RPM to get a response.

A World Champion's comment

I am very happy with the general operation both forward and in reverse. We have a perfect compromise between speed and consumption, with few noises and vibrations.
Our boat is specially optimized for racing, the choice of the EWOL propeller was right for having the minimum amount of sailing resistance.

Sono molto contento del funzionamento generale sia in avanti che in retromarcia. Abbiamo un perfetto compromesso tra velocità e consumo, con pochi rumori e vibrazioni.
La nostra barca e specialmente ottimizzata per le regate, la scelta della elica EWOL era giusta per avere la minima quantità di resistenza a vela.

Perfect Propeller

Test passed, perfect propeller, I solved the problem of the stern moorings with ewol, I recommend it to the “alpisti” with the A42, excellent product and owner careful to take good care of the customer even after the sale, a quality that is now a rarity

Everything is fine with the propeller

Everything is fine with the propeller after having done as advised by you. Four marks to plus, good performance and regular diesel consumption.
Thank you very much, I remember it was a week-end when I needed your help – and I got it from you.
Warm regards
