Kayaking is a relatively safe sport, but all paddlers should be prepared for accidents. Safety basics section covers the techniques that are required to successfully recover once you have capsized. They are fast to learn and it is recommended you master at least them before heading out with your kayak.
After that you can learn to do braces and eskimo rolls. They are always a better option and can often prevent capsizing in the first place.
Remember that knowing how to do something in practise situation is not the same thing as actually doing it when the waves are big and you are tired. So keep practising every once in a while.
