Boisa has still not commented publicly on the disaster and has refused media interviews, but is reportedly cooperating with the investigation. The police interview further revealed that Boisa admitted to having a shot of whiskey about two and a half hours before the boat sank. The autopilot detail may or may not be relevant to the cause of the boat's listing and sinking. Per the Chronicle, autopilot on a boat like this is simply a steering aid, and does not prevent collision or any other sort of problem. Or, as another experienced charter boat captain noted early on, the stability of the Volare could have been compromised simply by the captain not being vigilant about the even distribution of his 19 passengers.
