Rolf you do very nice work! Its great that you are building a boat, most of us just talk and never do. Part of that for me is the money doesn't make sense. I can scrounge (have more boat parts than I care to admit) but the major costs of mast, rigging, beams and sails aren't going anywhere and still run $10K if bought new I guess if you built molds for the hulls, molds for the mast you could build an exotic boat for cheaper than buying, excluding labor. Would be a fun group project.
