Combining a creative use of new technology with time-honored techniques produces the signature look of Sea & Soul Nautical Chart Art. All of our topographic nautical depth charts are rendered in beautiful detail by our graphic artist using a combination of maps. The art is then laser cut and engraved in our wood shop in rural Wisconsin. Our wood workers then hand stain and assemble each chart with the water depicting the bathymetric depth contours one level below the shoreline for a wonderful 3D effect. It is this attention to detail that gives Sea & Soul products a gallery quality look and feel.
