Notes:

1. Dimensions shown horizontally are distances from the AFT SIDE of the stern transom, since the side panels fit OUTSIDE the transom.
2. Dimensions are taken from a DATUM LINE shown in red above, which is a line drawn at 90 degrees from the bottom of the stern transom.
3. Dimensions shown vertically in BLACK are distances from the Datum Line to the top of the side of the hull (before adding the gunwale).
4. Dimensons shown vertically in RED are distances from the Datum Line to the bottom of the side of the hull.
5. Draw all lines shown on the inside of the panels. Cut approximately 2mm outside the lines and plane off excess after assembly.
