According to their website, Below the Boat is the result of an unabashed love for an often under-appreciated world that lies just beneath the surface. Made in Bellingham, WA by Robbie and Kara Johnson, these bathymetric charts (the underwater equivalent of a topographic map) are laser-cut into sheets of Baltic Birch, hand-colored and then glued together to give them depth. Each chart is then wrapped in a custom wood frame and protected by a sheet of Plexiglas. They're current inventory includes both the Salish Sea and the Puget Sound, as well as a number of other aquatic areas in and around the Pacific Northwest. I've already added one to my #wishlist.
