The easiest way to transfer the liner dimension listed is to create two marked tapes or strings that have the dimensions clearly marked as shown in the leading and trailing edges of the keel template. Locate this with a reference 0 at the keel/hull intersection. Take a sharpie and mark the keel with the locations marked on the tape. Then it is easy to use those marks as a guide to locate each of the template sections. This is how the Compukeel kits do it.
