Why not Cove and Bead?
For years, the state of the art in making strip-built boats has been cove-and-bead strips. Since most boats have rounded sectional shapes, i.e. the forms have a curved shape from the sheer line to the keel line, it is inevitable that each adjacent strip is oriented at a slightly different angle relative to its neighbor. If the edge of each strip is left square, this results in slight gaps in the seam between adjacent strips.
