Three miles offshore of the Farallons seems swimmable, but unfortunately it’s a breeding ground for great white sharks.

Open water, cold, waves. Even an expert swimmer wouldn’t have much of a chance.

There is a video out there of a killer whale mom with a calf at the Farralons.

A great white shark moves in to get the calf but the mom bites and kills the shark.

When I’d ride my bike to the top of Pacifica it was possible to see those islets, 26 miles away on a clear day. There was a marker up there that pointed to them, right by the old Nike Missile site.

Yes, I'm thinking that was the area where the tour boat witnessed the confrontation between a great white shark and a killer whale (orca). Interesting show.

I would say it is not swimmable. The currents are unbelievable. The Golden Gate is one of the worst spots. I have seen large boats at full throttle make little headway against the current.

If the water was bad enough to sink the ship then I imagine it'd make it hard to swim anywhere. Plus it was March so the water would be pretty cold.

Water temperature of 0^∘C doesn't help.
