Is it possible to make a foiling catamaran, 100% electric? Going 40 knots in sprints if required?
Only a generator as absolute last resort emergency, otherwise have the entire hull plastered in the most efficient solar panels, should be possible with 20-25 kW peak on a 50' cat.
And plenty of batteries.
I am just thinking, as soon as you are planing on the foils, the drag goes down. You can choose a shorter but faster run while planing, or keeping it slow for long range, even infinite, cruise.
I am thinking something like this one, but with electric engines:
2 x 250 kW electric, 100 kWh battery, 25 kW peak solar panels?
Sure batteries are expensive, but the price is coming down. And consider all the items you DON'T need for cooling systems and other diesel expenses - put it into batteries and solar panels instead. 7000 liters fuel tank, that's about 5 tons when full of diesel. For that equivalent weight, you could have 500 kWh hours of Tesla style batteries. Even 10X more if using a better (but 4x as expensive) battery type. And the electric motors would also weight a lot LESS than equivalent diesels.
Thoughts?
