So i thought this fits here, he calls the boat Helios 11 and builds it with very little experience. He docunents the adventure quite well and shares what he learns, and also shares all the plans for the boat for free.

Now I've watched the video, there is no ballast

He does end up adding ballast later. Added batteries, living stuff and about 150KG of rocks.

His takeaway was that it didn't really affect cruising speed and that he should have made a sturdier, heavier bottom hull.

Edit: he's in the process of turning it into a trimaran at the moment also for stability.
