The BBC reckons that could have made it.
If the trio had left at midnight and had paddled hard to the north, then the strong currents could have worked in their favour.
"If they hit it exactly at midnight, the beautiful thing is that we see that they would have been sucked out towards the Golden Gate Bridge," Dr Hut told BBC News.
"But the moment they were close to the Golden Gate would have been the moment the tide reverses.
"And that would give them a moment of slack tide, in which they could have reached marine headlands in the northern site of the Golden Gate Bridge."
