How to patch a canoe slalom boat.

I’ve created a step by step guide of how to patch a canoe slalom boat. Its got detailed instructions accompanied with a video showing how I did the repair.

Needs more attention to one versus
more layers of patch, to fiber orientation (bias cutting), to ovaling the patch corners, and to patch material. Even my slalom boat is not carbon on the outside, but S-glass, so I would not use carbon. The resin ratio depends on the manufacturer, and 4:1 would not suit with West, where 5:1, 3:1, and 1:1 are specified for different resins and mixes.
