hey all, I'm new to building kayaks and to this forum in general, I'm currently lofting the frames for a kudzucraft curlew, and I'm running into difficulty after Ive laid out all my lines (or chines i believe they're called), when i get to the lines for the deck ridge there don't seem to be any coordinates, or even an angle measurement to draw the lines to, can someone please explain somewhat if possible? the author of the book I'm using (fuselage frame boats) doesn't seem to go into detail about this particular subject. thanks all!
