My Solar/Electric Catamaran


 
Edited

I've been working on this project for a couple years and it's been 3 steps forward and 2 steps back but I'm getting close.
I made a video that shows my work, I hope you like it.

Lookin' good.
I found that adding a plastic fairing around the motor's shaft greatly reduces the drag at higher speeds, so you get a higher top speed with the same motor and prop.?


I have a small trimaran, and the motor itself seems to cause more drag than the hulls. Your cat hulls are probably similar.

Interesting. So if I took off the rudder and added a fairing, the fairing could act like a rudder?

Yes, I think it would, depending on the surface area.
