The Amphora "Dragon"
When my two youngest sons were 8 and 9, we built a boat for them. They did a lot of the work. We used a Ryobi circ saw, scroll saw, and drill motor. The boys are 15 and 16 now but Dragon is now being used by my grandchildren. It looks like a Viking dragon boat. My sons sailed and rowed it on Grand Mere Lake in Michigan, "raiding" picnic sights along the shore for hotdogs and marshmellows. They also searched for treasure in the lake bottom.
