That's the last 3 times out on my ski and I've seen a huge shark each time, this latest one was about 1km behind Green Island and I reckon 14 foot long (or bigger) with a 3 foot long Tuna dangling from it's side foul hooked.. I would say someone lost a decent fish this week end and it ended up on the side of this shark. I think he wasn't real happy about the freeloading Tuna as he was swimming fin out of the water and at a fair pace.Again I tried to get pics but by the time I get my camera out and pointed it had gone deep. And I didn't feel comfortable waiting around to see if he was going to resurface as he may have wanted a matching jetskier on the other side to the tuna.
