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.

Uhm. This is not done by welding a bit or using big bolts. If done wrong, your “catamaran” will not survive a single wave, let alone the conditions of the open sea. Don’t forget how much force water has.

So if you do this on a lake, you’ll be fine, but not in open waters.
