This blueline lofting is printed on 24# stock and measures 42" wide by approximately 18' long. That's a substantial piece of paper. Fortunately, it can be used like a scroll, unrolling what's needed at the time and nothing more. That's particularly handy when you're short on uncluttered space (and who isn't?) So why purchase a lofting? For one, this lofting comes from Walter Simmons' shop in Ducktrap where he builds these wherries, and he is the one who drew the lofting. For another, it will help you save precious time so that you can go directly to getting out the moulds and backbone and getting your wherry set up. Your call, of course, and if you ultimately decide to loft her on your own but are a bit hesitant, then you'll want to take a look at Lines, Lofting & Half Models, also done by Simmons.
The photo above was taken prior to setting up a 15' Lincolnville Salmon Wherry. It shows body plan stations (moulds) extended to a common line which represents the surface of the building platform on which she was to be built. The photo below shows the lofting being used to verify the stem and knee and their fit to the plank keel. When you're setting up your boat, there is nothing more useful that a properly executed lofting.
