I've had my Thoosa 9000 EP system installed since 2008 and it has been so much more reliable than the diesel. I would not hesitate to do long time cruising with the system. One of the factors I looked at when I first thought about installing EP was how I might do a long term motoring trip like going down the ICW down to Florida. One of the reasons I choose AGM batteries over Lithium was the easy availability of AGM replacements locally in the U.S. or elsewhere. Though my AGM bank is still going strong. The rest of the system is pretty bullet proof. I've carried some spares (like a battery charger) that I have never had to use in eight years.

My opinions.
1. Reliable - yes.
2. I would cruise.
3. Batteries keep getting better and cheaper, at 7-10% y/y.
4. All good electric solutions dont use the hull for anything on the
motive side.
Metal hulls wont matter.
Higher voltage = better efficiency.
Larger prop = much better efficiency.
