As I mentioned in my original post about the 1897 Lark scow, Bill Kerr redrew the plans for the Erieau Y.C. fleet in 1963. All the new Lark builds at Erieau Y.C. follow his plans. Peter Gilbert from the Erieau fleet has kindly sent along the Kerr plans. I chunked them into two PDF files; an instruction manual PDF and a drawing PDF.
