When i was learning to surf in Cornwall a couple of years ago. There ware warnings all over about riptide and i just stupidly ignored them thinking this fairly large wave would be easy enough to ride in on (bear in mind this was probably my second day of surfing and i could barely stand on the board). I rode it in a little bit and fell off. I went under water and got pulled back by the riptide, my board followed and smashed me in the face dazing me and i 100% disorientated in about 10ft of water - i really thought i was going to die. Riptide is so much more dangerous than people think it is.
