Snuck up behind a Hammerhead at Scarbs. When I was a few metres away he tried to dive too quick, his tail came out of the water so couldn't get traction and I ran into him. No damage done but did feel sorry for scaring him.
Also had a big Hammer at Lanno surfing the same swell I was riding at main break. I was going like stink to stay on the wave and remember the spay coming off his dorsal fin as he came in from a 45 and shot straight under the board and out the other side. I was maxed out speed wise and this thing left me for dead (maybe I should re-phrase that

). At no time did they ever feel a threat, it's when you run from most predator species that they'll come after you.
