Back in the summer of 2007, I went to the Wooden Boat School in Maine with my granddad, and we took the Build a Shellback Dinghy class. We made very slow progress on the boat after that, and it is only now finished. The boat is made out of marine mahogany plywood, and it is just over 11 feet long. It has a mast, spars and sail in addition to oarlocks, but they do not fit on the boat in my granddad's indoor wood shop.
