Which wood to make my Kilaia?
You can use any wood that you have at hand; Pine, or even Plywood but ensure it’s marine compatible. The denser the wood you choose to use the more weighty your board will become. These higher density woods weigh much more than Paulownia or Cedar but most wood types work and the only inconvenience about a heavier board is when you have to carry it to the water.
One key consideration, regardless of the wood type, is to ensure that all glues used to construct your board are waterproof, exterior specific (marine-quality). This is very important as you do not want your Kilaia falling apart when you are riding it.
