Apologies for the curved lines that come from a wider angle lens.  Here's the body plan, all done.  These are the sectional slices of the boat, taken every 2' or so.  Since these lines show the outer surface of the boat, we will need to deduct the thickness of the planking in order to make the molds that will define the shape of the boat.  If we made a mold that went exactly to these lines, when we came to the point where we bent planking around the molds, the boat would be too big by exactly the plank thickness.  

Subtracting the planking thickness is so easy it's embarrassing.   We cut a small piece of wood, say 3/4" wide and a few inches long that is exactly the thickness of the planking.  In this case, the planking is .72" or 47/64" thick.  Don't ask.  This little scrap of wood represents a plank.  We'll call the faces that are .72" away from each other the inner and outer plank surfaces.

Anyway, we take that little scrap of wood, called a fid, and place it so that the outer plank surface is right against the station line.  We then make a little mark along the inner plank surface.  Do this all along the station and you eventually get a series of dashed lines that are exactly one plank thickness inside the station lines.  Connect those dashes and you've got yourself a line that you can pattern your molds on.  We'll be drawing those lines and making the molds over the coming week.  

While the lofting has been going on, other members of the crew have been preparing stock for the floors, the stem, the keel, the frames, the horn timber and the stern post.  Even though it's relatively dull work, it feels good to get all this stock milled up ahead of time.  We'll be making patterns for all of these parts very soon, and it'll be quick work to cut them out now since the stock is ready to go.
