first builds
Sounds as if you'll just have to trim the frames down until the planking does lay fair across the length. I wouldn't worry, I don't think it is too unusual a problem in scratchbuilding unless you are an expert. Interesting boat for a first build, is she a sailing or motor Fifie?
When the winds before the rain, soon you may make sail again, but when the rain's before the wind, tops'l sheets and halyards mind
