Yes, our partner Naviwatt in France
has done that switch multiple times and results are very good !
I have seen comments saying that solar
power will be insufficient, and that is true. What most of people don't consider is that a sailing boat can recharge batteries not only through solar
but also with hydro-generation given by our high efficiency propeller
in recharge mode.
That is a key point because it will be enough to have wind
blowing = water
stream on the propeller
= recharge your batteries.
An EWOL prop on an electrical
powered boat can go into feathering position as needed (when the batteries are already charged for example), then she can go into recharge position when you need to recharge you batteries and then she can go to propulsion
when you need to maneuvre or there is no wind. All this from aboard...
I have a couple of examples for you:
1) Ewol is the supplier of propellers to Itsara, world's first 100% electric catamaran
, and Alibi 54' where propulsion
and power generation are assured by 2 EWOL Hi-Speed (hi-efficiency propellers) performance - Alibi Catamarans
2) Amasia is an older boat, where the diesel engine has been replace with an electric one, this boat has almost completed the world tour, the team left 1 year ago, starting from France
, then went to Cabo Verde, crossed the Atlantic, passed the Panama
strait, then Fiji
and are now approaching Madagascar
.... all this without diesel, just wind and electricity.

Take a look at this interesting video to see how the system works (multiple language subtitles available)
If you want to know more just let me know....we supply these systems pretty regularly !!
