Went to the same place again yesty morning, and the same thing happened...paddled out to the nice spot then the blowie turns up and starts buzzing us, so we paddle up to a less inspiring peak and it follows us, so we catch the white-water in and walk back to the first spot and after 5mins it shows up back there?
This isn't the only time it's happened, 1st time one bit 'ol mates toe half off, another time i was changing the prop on a boat and 4 of them were after my ears, 3 times at this spot.
FYI, these critters are about 3ft long with a parrot fish like beak ( ivory so i'm told) that can bite though a hook...a big hook!....we call'em bolt cutters for a reason!!.
The Japaneze love'em, it's a delicacy there, expensive too, ...Gotta have a good chef tho, one that knows what he's doing.

Set Drum lines?
