Special thanks to Neslon Highley for his permission to publish his article on Royalex canoe repair.
I’ve been doing boat repair for many years. The following PDF article accurately reflects the best methods I’ve found and that I still use for most ABS canoe repairs. I’ve used the methods for large plates over worn cracked spots on the exterior, small cracks and holes, and even restoring the inside of hulls where D-ring pads have been torn out to be able to put new D-rings in. The instructions are easy to follow. The only caveat is that the work is tedious and labor intensive, but the results are usually very good.
These instructions may seem a little complicated at first, but it really is a pretty simple repair that produces great results.
