I am confused about the dimensions for the keel. The Materials List states you need a 3/4" X 5" X 8'6" Mahogany. However the "Layout for Outer Keel" on dwg #6 shows a 1X12 Mahogany. And if you crunch the numbers on the Layout you will need a minimum width of 6-3/4". Does anyone know which is right.
