Now, after almost 400h of work, I also believe so! The plans have some mistakes but they are precice enough and they give you a step by step guidance throughout the process. As for the tools, there always seems to be a simple, low tech way to do things. You just have to use your imagination but, I guess, this is something you start doing the moment you choose to build a boat like this.
Some friends came over a couple of days ago to help me lift the hull and place it on mounts. The moment the two hullsides, wire stitched along the keel, stem and stern, were opened and the starboard hull took shape in front of our eyes, all my doubts and fears were gone. For the first time I was certain that what I was building in my garage was the boat that would take me to the seas I dreamt of!
