The sheer clamp is the thin long piece of pine at the top of the side panel. The chine log is a piece of pine that runs the length of the boat were the bottom. The sheer clamp is the part that you would nail the top to. The chine log is the piece of pine that is used to nail the bottom on. The boat is 15.5' long and you can only buy the pine in 10' long sections and thats why you need to make a joint. The scarf joint is when you cutt to pieces of wood and glue them together. The way ou cut them would be at an angle the angle we used is 6''. Then you would need to glue them together with a special type of wood glue. Then you would need to press them together with clamps to make sure it stays in place...
