I've just come back from the sawmill with a truck load of white cedar that I will be using for a boat maybe a year from now. It's mostly 6/4 10" - 20" wide, 10' - 12' long, straight grained and 90% knot free. Because it's still green I got the whole lot for $150. I am feeling very content right now. After this post I will go and paint the ends and stack it on the shady side of the barn. My question is about the sapwood. Is it usable for boats or will it rot and attract insects like most other sapwood?
