Typical range of a yacht under electric propulsion is between 20 and 50 miles, OK at a pinch for a long weekend coastal but could be a considerable handicap offshore unless you are in one of the worlds windier places when you don't need a motor anyway which is the essence of a sailing yacht.
As ever, it's about matching the technology to the requirements.
Crossing the pond from east to west would not be such an issue in an electric drive boat. A friend has just done this in a Contessa 32.
Innefficient actually unless they are Brushless - then you have a much better form.
I think that yachties worldwide are going to have to come to the same painful admission.....they need a catamaran
We have 14kw of storage on the boat. Its kept charged by 1300w of solar in the tropics. Now we are getting towards summer we have an excess of solar power. I have to keep thinking of stuff to use electricity for

It is well over 100 miles if you want it to be but that still misses the point that only electric can regenerate when you run out. Electric range is not what the battery manages, range is how far you can go before going to port. Electric is unlimited.
Oh remind me again how fast a diesel goes when the tank is empty? Reread my post. Electric with solar has infinite range.
Absolutely wrong. Range is the distance you can go between ports and with solar that’s infinite. If you have a time related issue that’s different.
That’s time pressure, not range. A self filling tank has infinite range. If you’re in a hurry then a product with lower range but faster execution is a good option. The diesel absolutely has lower range though.
I would say the range is what you could achieve with whatever batteries you have without charging just as the range of a diesel engined yacht is whatever it can achieve with a full tank of diesel which is how boats are described.
You do have a point but it is an argument against not for as with a typical 48V 40kW hybrid motor with somewhere between 500 and 1kW solar array that's going to take quite a while to put enough in the batteries especially if you don't want to ruin them by continually depleting them to zero charge. Food and water would become more of an issue.
my catalac has 30kwh. my house only has 15!
Really? Even if you could gather more fuel as you go? Seems like a definition used to prevent progress rather than describing how far the power system could propel the vessel?
