some of the situations I have seen missed rolls by very competent paddlers,washed onto a wave cut platform and too shallow to roll up,sucked out of the cockpit after getting thrashed by a big wave,rolling up in strong winds and the boat being blown back over by the wind,snapped paddles,stuck between rocks where there was no room to roll,plenty of reasons usually not mental issues,when I was doing my instructor training ,our instructor used to paddle,sneak up on you and push you over and keep pushing you over until you had to swim,thats how much emphasis he put on self rescue,even when you were being nice to him like offering him a chocolate bar.But it was a good way of learning not to panic,good exercise for your ears too,I can now hear a paddle entering the water from 30 mtrs away,remember guys ,just living life is full of risk,if you remove all risk ,you remove life itself.Magooch why don't you try paddling in more extreme circumstances ,your paddling skills will improve dramatically.
