Step 16: Gunwales, Inwales and Thwart
Start at the bow end and place one piece on the inside and one on the outside. these are your Gunwales (Pronounced gunnel) and Inwales (pronounced innul). Clamp these so that they and the sides are all as even and level as possible. Screw through all three pieces. Don't worry if the screws stick through a bit we will fix that later.
You are going to be about a foot short on each side so this is where you use the fifth piece you cut.
At this point you can remove the temporary frame and set it aside.
I wanted a bit more rigidity so I took the remaining piece of the 2 x 4 that I had used for my chine logs and transom framing measured the width of my boat at the 42inch point and cut the piece that is now about 2 x2 to fit in there and attached it with two screws per side. You can cut angles at both ends so that you get a nice tight fit. I did this by angleing the miter guage and sneaking up on the angle. It should be about 15 degrees.
Note If you are not doing this for a contest like the one I entered you will want to use a good quality adhesive for this step.
