What this video covers

Johan and Malin are constructing a structural keel grid for their boat using Sapele timber instead of the previously planned Kaya or Sippo mahogany.3:27 Johan selected Sapele for its superior strength, rot resistance, and epoxy-bonding properties, noting it performs similarly to white oak but at a lower weight-to-strength ratio.4:20 The grid design prioritizes toughness and impact resistance for potential groundings over the weight savings of a foam-core sandwich construction, adding approximately 150 to 170 kilograms to the hull.7:33 Johan uses a laser level aligned with the boat's centerline to mark precise beam positions and employs a 3D scanner to create digital profiles for each floor beam.1:03 These profiles are cut using a Shaper CNC router, with biscuit joiners used during the glue-up process to prevent slippage.16:34 The project involves sanding the interior hull to the waterline in preparation for a barrier coat, though access remains difficult in the aft sections.1:23
