I have never seen any mention of a Lumberyard Skiff on these pages. However I have seen it mentioned on Wooden Boat Forum. Here's an informative link I found.
I see that you have found WoodenBoat Forum. Between these two forums you should be in pretty good shape. I see also that you have a lumbermill. What woods do you work with?
Welcome. What kind of Mill do you have? I have been eyeballing a Woodmizer LT40 as of late. The price is right, the hours low, and I have access to lots of logs. I'm very interested in this as my next endeavor for personal and part time use. I don't have dreams of full time sawing for profit, just enough to pay for the mill and use it for a few camps that we are working on in the next couple years.
