Sending you some photos of my modified version of Overnighter. The boat is built according to your description. I have made some modifications. I have lengthened the boat 200 mm. The wind-screen is moved back about 200 mm and the cabin is shortened a little. I have used 7 mm x 5 layers plywood for the hull. To finish it, I have used strips of mahogany with thickness of 5 mm and 50 mm width.
Engine: 90 HP Evinrude Mod.98
