Oh I was definitely at the edge of my abilities, and I agree with you about practicing self rescues in conditions.
But I think it is also important to improve your paddling skills by paddling in rough conditions. I you have good technique you may avoid capsizing in the first place.
In this case we were on a trip with Atlantic Kayak Tours so I knew their guides would rescue me if neccessary, we would not have paddled in those conditions on our own. We have paddled a lot with them just for that reason.
