Lofting is the art, science, or craft of drawing and perfecting the lines of your boat, full size. It is far easier to correct mistakes before you make them out of wood. I learned lofting from Greg Rossel, and will never again attempt a boat without lofting it, no matter how “dependable” the plans are. It not only allows us to make the ideal curves and shapes, but it gives us exact patterns with which to make the parts.
