Today we began making the ribs for the boat. Seven are required to outline the basic shape and 8 additional ribs will be laminated in place after the keel and gunwales are formed. The photo below shows the half model, tracings of the various layers of it and a table of offsets developed from the tracings. In the table of offsets, the measurements on the right of each set are the distances scaled horizontal from the centerline to the outside of the hull. The measurement at left is scaled from the distance from the top edge to the keel of the model. The table of offsets is used to locate the various points in the curvature of the ribs so they can be laminated to the required shape to form the width of the hull.
