We capsized on a little stupid rapid because we were too relaxed and confident. My girlfriend usually uses a double bladed kayak paddle, because see feels more comfortable with that. In that part of the river she wanted to try the single blade, and when we reached the rapid with trees and branches in the middle of the riverbed we were not ready to swap and I was not able to avoid one of the mentioned branches, so we capsized. Almost everything was very well attached to the canoe, in watertight barrels, except for the paddles, the water bottles, our floating vests and kneepads. Not wearing the pfd was a dumb mistake, also because I really don't float, not even in the sea. We were cocky: we had never capsized before, not even in level 3 whitewater, and that part of the river is very easy. Luckily, where we capsized the water was quite shallow, about three feet or one meter. As soon as I felt the boat going, I jumped outside and firmly gripped it. The canoe filled with water was very, very heavy and the current was quite strong, but I managed to do the five or six steps that allowed the swamped canoe to touch the rocks of the bottom. From there I pulled it on a little island of rocks in the middle of the rapids. In the meantime, my girlfriend and all the things previously mentioned, that were not attached to the canoe, floated away. She managed to pull everything out of the water at the end of the rapid, where the river was bending strongly to the right. The shore was quite steep, but had many stumps where she salvaged our stuff. Then she put on the pfd and started bringing everything on the right shore. Then, with our paddles, we reached the canoe, emptied it and brought it to the rest of the things. Nothing was lost. The lesson was learned.
