just like when you're doing a preliminary diagnosis on a rare car, checking every nook and crankshaft to ensure nothing gets overlooked, analyzing a canoe's build is quite similar. you've got to refresh your knowledge on the materials and techniques used, ensuring they're up to spec. but here's a twist, just like how sometimes you might disown a car that's beyond repair, i'm curious about the sort of questions that might make you barred from participating in traditional canoe races, essentially what action or question would lead to being disowned by the canoeing community?
