The photo shows the location of the stainless bolts that I used. Near stations 6 and 7. If I were to do it again I would have moved them forward 4 inches or so. I think I used about 3 layers of 6oz to attach them to the hull. I also put an extra layer between the bolt and the hull the length of the foot brace.
On the next one I’m going to use Nick’s adjustable bulkhead type of foot brace. It should be more comfortable.

Hope this helps,

Lennie
