He hasn't paid for fuel in 10 years, has never run out of charge, and was inspired by a famous race across the outback. Retired industrial engineer Ziga Dorkic wants to show you how it's done — for the Earth.
Thought of you fine folks when I came across this article on aussie.zone
Well to go slow you only need very little power. But it goes up exponentially much more like with wheels. So you need to design a boat that is long, thin, light and with a large roof surface area. Basically a catamaran or a power trimaran. Then you want glass solar so it’s affordable and lasts 20+ years but that is top heavy. But theoretically with the right design solar panels are cheaper than a sail and less complex and easier to maintain than sail+motor+house battery.
But 4-5 knots (~mph) is quite easy. From my amateur calculations 6-7 knots is already hard. I mean those speeds that are sustainable for 24/7 cruising. If you have a large car battery you can go vrooom for a few hours and then slowly recharge over a few days. But my goal is really a slow but seaworthy condomaran.

If you make it comfy enough you won’t mind the slower speed.
