The size is 11m, multihull, as a liveaboard. Probably 2-4 years to accomplish as a solo part-time careful amateur. So better to ask for skilled help to accelerate things.
The reason to build new is to get things the way I would like. Buying an existing (much older) model would likely entail so much demolition, repair and rework that it would be simpler and more pleasant to just build from scratch, using more modern materials and techniques.
I was concerned about the weather in terms how much humidity is in the air while the epoxy work is being done. But I see they build in the Philippines, for example, so perhaps that is not insurmoutable.
For the residency aspect during the project, that is not too difficult -- one just needs a trip abroad now and then to go get supplies. Or just apply for residency, if that makes sense.
But I am concerned about the "balance of power" if employing someone else, as David rightly points out. To that end, I am reading everything relevant. Thus this inquiry as to what others have done or would do.
I did look around on the web for boat builders, but most want to build with expensive foam, for that lovely Clorox bottle look. My thinking is much more classic and minimalist, so plywood/epoxy is the way to go.
I did turn up one outfit in India which looked like they would like such a project, but that seems much too iffy for me.
Where have all the backyard builders gone?
