As I regularly seek to do, materials were sourced giving preference to rescued materials and, in particular, this boat features approximately 25% recycled power-poles that had originally gone into service in 1941. After 80 years of holding up powerlines, these poles were destined for a burn pile, and were rescued by an enterprising sawyer. The cedar was very knotty and unsuitable to use for the entire boat, however the dark strips in the boat are primarily those from this recycled material.
