Laser-Cut Bathymetric Charts

Below the Boat (AKA Kara and Robbie Johnson) lasers bathymetric charts, the underwater equivalent to topographical maps, out of birch. Water is shown colored blue for easy reference.

(T)he contours are laser-cut into sheets of Baltic birch and glued together to create a powerful visual depth. Select layers are hand-colored blue so it’s easy to discern land from water, major byways are etched into the land, the whole thing’s framed in a custom, solid-wood frame and protected seamlessly with a sheet of durable, ultra-transparent Plexiglas.
