Having completed making the bulkheads, it is time to cut out the Longitudinals which form 2 internal “walls” bow to stern and will hold the bulkheads in place while planking the hull.
Unlike the bulkheads, the plans do not include a full size drawing to provide the shape. Instead there are a set of dimensions to give points along the hull curve. The photograph below shows bending a baton around the provided points to give the required curve.
And below is the first set of longitudinals all cut out
The first set become the template for the second set, so that the curve is identical.
