With the magic line drawn in and the line off for the topside planking calculated, it's time to take on the tricky area from the magic line down to the keel rebate (Uk) or rabbet (US). Lou Sauzedde and Ken Boyle figure out how they want the planks to run, how wide they are at the sternpost rabbet and how how many stealers are necessary to make up the greater distance below the tuck at the stern. Phew! A lot of words. It's much easier to watch how it's done. We'll also show a simple trick with a string to get a fair, pleasing curve in these lower planks.
