Using Schades book I am drawing the frame sections for the Guillemot but can't find the numbers in the table on page 54 which enable me to locate the deckline above the cockpit at frames 8,9 and 10. He explains that you need to do this in order to remain fair when stripping the hull by making the section above the flat cockpit line a removable piece. This makes sense but how do I get this shape?
