I agree, good thing this did not happen when you were on moving water in some rapids. I had a friend break the pin on his boat when we were floating the Big Hole a couple of years back. He was pushing off the beach and struck a rock. We had a spare oar with us but no spare pin. He was able to limp the last few miles to the take out. It was spring which made for some interesting moments. We came to a couple conclusions. 1. A spare pin should be part of an emergancy kit along with a patch kit. 2. Standard oar locks are still the best option for moving water.
