Has anyone built a kayak using pawlonia as the main building material? I found a source here: http://clearwoodpaddleboards.com/surfboard-grade-paulownia-planks/. They have 6 x 3/4 x 8' planks. It appears to be plain-sawed lumber, with various grain. I know I'll be making a lot of scarf joints on a 15' kayak. How is pawlonia to work with?
