This is a modern plywood updated version of the Japanese Yamato fishing boats. The client in this case, worked in Japan and admired these boats - he was able to obtain the lines from one example and gave it to us so that we could draw up a simple plywood version. the simple flat bottomed double chine hull form is similar to some of our motor boats and is an easily driven and stable shape. She is mainly open with large lockers and a small forward cuddy. sail power is provided by a simple unstayed lug rig and she has an inboard 9 hp diesel. Along with the centreplate and skeg is stub bilge keels which allow her to dry out upright. All in all, she is a practical sea boat. Construction is ply over frame with the frames, girders etc set-up on a strongback.
