How to Build a Pirate Ship from Wood? Fur, lots and lots of Douglas Fur.
From the History page "The principle wood we will use is locally grown and harvested Douglas Fir, which will form the major structure, masts and hull of the vessel. The Douglas Fir for our ship has been generously donated by the Conservation Fund from their 50,000 acres of sustainably managed forests in Mendocino California. The Conservation Fund is rehabilitating these forests to be commercially productive through stewardship management while also creating a healthy and biologically diverse forest. By employing a mix of conservation and preservation techniques the Conservation Fund is able to protect portions of their forests from logging. This preservation sequesters carbon in the forest and allows to the Conservation Fund to generate substantial income by selling carbon credits."
