Just so sad, my father is an experienced canoeist and kayaker, I spent many many holidays plonked in the middle of an open canadian on rivers and seas and only capsized once. I think it was carrying too much weight so could have easily just sank having taken on little water 
I'll never forget once talking to a family where the woman was wearing her LIFE jacket back to front so she would have drowned had she capsized as it would force her on her front!!!
I'm not into canoeing or kayaking but have a very very very healthy respect for water, the unseen currents and undertows, I am so glad that I have that awareness and have witnessed many careless attitudes towards the sea at beaches I would like to see far more education about water and to be careful of it.
