Given a few quartering waves off the bow and some headwinds and that 40nm will drop rapidly. I would stick with our 27' C&C MkV which will go for a couple of days on on <15gal of diesel with its 8hp Yanmar single cyl diesel. With any breeze at all we could go out for a week or two on a tank of fuel. Can't beat sails for eco-friendly.

Also, saying it can cruise "without emissions" doesn't really cut it for me. Where does the charge for the batteries come from? Solar cells are fine if the weather is great, but 150sqft of same isn't going to get you anywhere once the batteries are exhausted. Have to fire up that IC engine to get a reasonably fast charge or run the prop(s). Or, if charged from the power grid, even in the majority of Europe they are still 35%, or more, fossil fuel generation. If you want to go somewhere in a boat (or more especially, a ship) you are only really going to do so with either an IC engine or sails. Think it will be a while before we actually get to a practical non-fossil fuel power source on the water (other than nuc).

Do you have any first hand experience with the Greenlines or any other electric boats like the Azura Marine?

Absolutely none. But I do have 60yr experience of sailing/boating/ships experience and being a graduate level engineer know enough to live in the real world and recognize their current limitations.
Nothing at all wrong with the Greenline and Azura boats and I applaud their efforts and feel sure they will continue to get better as the technology of batteries, solar conversion & electric motors advance. They appear to be comfortable & well made, eco-friendly boats for those who never leave the sight of land. Indeed, they seem to be an economically viable alternative as a pleasure craft for landlubbers.

Sorry......... I missed your "Great Loop" use. Could well be an excellent choice for same, though I would not want to do so in a 100% electric boat. Being stuck in port waiting for a part to arrive from Europe, even for a new boat, might get old. I would want to check out the drive system to insure it is made up with non-custom parts so they are more readily available.
Been trying to get my wife to agree to do something similar with a small diesel trawler-yacht, but she feels we are too old and would break down before the boat.

Thanks to their bank of lithium batteries and electric motors, the Greenline 33 and 39 can cruise silently and without any emissions at a speed of 7 knots and to a top speed of 11 knots. With their battery capacity of 80kWh, they have a range of up to 40nm on a single charge.
40 nanometers? That's pretty small...40 billioths of a meter.

With options, the 33 is around $400K and the 39 is around $600K.

CDG - are you an experienced sailor?
Like RVs, the bigger the boat the further ahead you have to think/plan when operating.
Hopefully you can get aboard one to 'look around'.
