Proper foil shapes will have a strong influence on the performance of your sailing canoe. It is especially evident when you decide to test your speed against a class racer with an experienced sailor driving. Craig Walsh, one of my Ulua builders in Canada, shows a way to get that perfect shape:
"Attached are the pictures of the router jig for making foils that I recently mentioned. In my experience as a woodworking teacher, there are people who prefer not to make jigs, feeling that any time spent not directly working on a project is wasted. I'm of the other camp; if I can break roughly even on the labour I prefer to make a jig. It's all gravy after that."
This router jig makes a NACA 0009 foil with a two point contact router base.
Setup ready to go
First side of foil with uncut strips to hold the blank level for cutting the other side.
