Specifications

Every figure is GONG's own, read from the source linked in the last row. Weight is converted to kilograms where needed. Slenderness is computed here, length ÷ width. Board lengths are in feet and inches; widths and thicknesses in inches. Explicit source imperial figures are retained where they agree with the stored measurement. Otherwise lengths are converted to the nearest 0.1 inch and widths and thicknesses to 0.01 inch, using exactly 25.4 millimetres per inch. Volume stays in litres. Missing dimensions stay blank; calculations and drawings use the unrounded stored figures.
