I wasn't comfortable with the attachment brackets for the foot pedals that come with the pedals. I sometimes put a lot of pressure on the pedals and was worried that the small screws, only attached to the gunwales, would eventually tear out. I also didn't like the idea of so many screw holes in the gunwales so close together, weakening the wood. I came up with an alternative design that attaches both to the gunwales and chine stringers. I was able to get a small piece of aluminum (1/8 thick x 1" wide) from a local welding outfit. See photos for full explanation.
In the unskinned photo, the top bolts are only there temporarily. I removed them, did the skin, and then re-added them. That way I could also use the same bolts for attaching some of the strapping for my deck bungee chords. The bottom ends are attached with screws instead of bolts so that bolt heads won't make bumps underneath the skin. I added some heavy thread for extra strength.
