Bottom line: "Forgetta 'bout it."
The trips out to the Faralon Islands are long and expensive and there's no guarantee that there will any sharks or that, if there are, there will be any visibility. Chumming and baiting is forbidden.
I don't know of any local divers who have ever gone out there.
We dive year round with the knowledge that they're somewhere in our area and have adopted the idea of not messing with them and, so far, they've returned the favor.
That said, you'll be coming at a GREAT time to get some GREAT diving in around the Monterey area.
